How to cut siding plastic and metal: tool choice

Having decided to independently finish the facade of the house with vinyl or metal panels, it is necessary to study the technology of this process. It is relatively simple, and in the instructions attached to the material, each stage is described in detail and schematically described. But it has very little information on how to cut siding plastic or metal.bending. recommended tools with brief explanations are simply listed. In fact, make them a flat and neat cut without creases, cracks and crushing the profile is very difficult. Therefore, you need to not only choose the most suitable tool, but also know how to use it correctly.

Regardless of manufacturing material, siding panels have a complex figured profile. One of their longitudinal edges has a castle, and the second is the response part, snapping into the groove, and a strip with an ozium for fastening to the frame. The visible part of the panels is embossed and can consist of one, two or three or three identical waves. And their thickness does not exceed 1.2 mm.

It is the convex relief in combination with a small thickness and the presence of hard multilayer locking areas that causes difficulties when choosing a tool for cutting siding. As practice shows, for each type of saw, different devices are more convenient.

The facing panels, depending on the installation site, have to be cut in the following ways:

disk, plastic, thick, walled, pipe, polymer
  • along the entire lamella to fit its width to the cornice in the upper part of the wall;
  • across the lamella to obtain the desired length;
  • at an angle for facing the pediment and its design along the slopes;
  • manufacturing curly saws for installation around the openings and protruding elements of the facade.

In each of these cases, you need to choose how to cut siding will be more convenient, easier and faster than all.

Dobges for decorative design of the cladding have even more complex form. And if the neat edge is not very important when cutting the panels, since it will hide in the grooves of the finish, then the appearance of the inhibits should be impeccable.

Cutting tools. Analysis of effectiveness when working with siding

Experts recommend cutting plastic with the same tools that are used for cutting metal products. Therefore, we will deal with them in relation to each type of panels.

This tool is mentioned in all siding installation instructions. They say that before cutting siding vinyl or metal, you need to lay a flat rail on it along the marked line and several times with pressure, draw a knife with a pressure along it. And then turn the panel over the resulting groove.

These conditions can only be fulfilled on a flat plane, pressing the panel to the solid base. The curved relief of siding will not allow you to make a neat cut across the panel, it will be especially difficult to cut the material in the castle part. Therefore, the knife can only be used for longitudinal cut and provided that the marking does not occur on the crest of the wave.

Kryazuvka for metal

A hacksaw or saw with a very small tooth is suitable only for transverse cutting due to the small length of the working sheet. This tool has too many disadvantages that do not allow it to use it with large volumes of work.

  • Low speed and high labor intensity of cutting.
  • The difficulty of cutting the panels along and at an angle.
  • The impossibility of making curly cutouts.
  • A flexible canvas goes away on bends and multi.layer areas.
  • You can cut plastic siding only at a plus temperature.

Choosing how to cut metal siding, a hacksaw for metal can be borne in mind, but all the cuts should be hidden by inputs, since they have not too even and neat view.

Scissors for metal

Like other manual tools, scissors cannot be used when working with plastic in the cold season, since when cutting them the material may crack. And this is not the only condition for achieving a good result. It is also recommended to choose scissors with a minimum thickness of the cutting parts and not allow them to complete close close.

The latter condition is easily feasible in even single-layer areas, but, cutting the S-shaped castle, you have to make a great effort, as a result of which the blades of inertia are closed, and a crack is formed in front of them.

The quality of the tool is also of great importance. its acuteness, the absence of a backlash between cutting canvases, comfortable handles.

But there is always a risk of cracking panels, their crushing in the places of bending of the relief, flattening of the castle profile. Especially if you cut thin metal or fragile plastic of poor quality.


An electric jigsaw is one of the most functional tools when it comes to how to cut siding. But for effective and accurate work, several conditions are required.

  • The saw should be small. for working on metal or special for plastic.
  • You must first choose the optimal speed of the file.
  • We need an assistant who will press the panel to a tough basis, preventing it from vibrating under a working tool.

When sawing a metal siding with a hand hacksaw or an electrician on the edge, bulletin can form on the edge. They must be removed with sandpaper.

Circular Saw

Cocking the siding panel in a straight line along or across you can also with a disk saw with a cutting circle. It is more convenient to make transverse cuts in a stationary tool, longitudinal and diagonal. manual.

But a heavy disc saw requires work experience and dexterity: it strongly presses its weight on the panel, which at high speeds vibrates significantly vibrates. If you do not fix it, the tool will take aside from the marking. In addition, the setting itself partially closes the saw of the saw.

When you need to choose how to cut plastic sofits, additional elements and vinyl siding panels, it is best to stop on an angle grinding machine (corner grinding). The following recommendations will allow you to get a perfectly smooth and unexpected edge:

  • The part must be well fixed or held to avoid vibration and movements;
  • The tool is better to take small, light, with low power;
  • The diameter and thickness of the disk should also be minimal;
  • The corner grinder is used at small speeds, holding it exactly perpendicular to the cut plane.

What’s The Best PVC Pipe for Underground Usage?

As for the metal panels, manufacturers do not recommend the use of a corner grinder for cutting it, since hot sparks fly during its operation, and the metal is very heated with the destruction of the facial stained layer, which can further lead to corrosion.

However, experienced finishes argue that the risk of such damage is minimal, if you choose a disk for metal with a thickness of 1.2-1.5 mm, work at low speeds and slowly, preventing the metal overheating.


This is a relatively new multifunctional power tool that can replace several highly specialized. Its peculiarity lies in the fact that the rotational movements of the engine are converted into oscillatory, so the cutting nozzles do not spin, like that of the same corner grinder, but vibrate with a small amplitude.

When cutting a renovator, sparks are not formed, the edge does not heat up, therefore, if you choose how to cut metal.screen, you can’t find a better tool. He can easily cope with vinyl panels. Of course, his speed of work is lower than that of a corner grinder, but the quality is higher.

Corner grinding nozzles. Types and features. Application

With proper use of an angular grinding machine, this device becomes a universal tool that is processing any material. In this case, the main factor is to choose the right nozzles for a corner grinder.

With the help of corner grinder, you can perform many different operations using different wheels and nozzles: to rip, sharpen, polish, and also perform other types of work where you can use the rotational movement of the tool.

Types of nozzles

There are many different devices and nozzles used when working with an angular grinding machine. Consider their main types, design features and application.

Cutting discs

These are the most common nozzles, which are produced by many types. With them, you can process any material. Popular of them were discs for metal, stone, wood.

  • Cutting disks for metal differ in diameter and thickness. In diameter in the retail network, you can find discs with a diameter of 115. 230 mm. The thickness of the discs ranges from 1 to 3.2 mm, depending on the diameter. These dimensions also depend on the speed of rotation and the load attached to them.
  • Stone processing discs differ from other species only by abrasive materials from which they are made. The remaining parameters are similar.
  • Wood wheels. The use of such discs is very dangerous, if you work inaccurate, you can get an injury. Such discs are essentially saws. It is forbidden to remove a protective casing from an angular grinder. It is better to use a disk for sawing wood with a small tooth, and do not use a large feed. The best use of such nozzle for angular grinding grounds is the use of special devices for inpatient fixation of the corner grinder.
  • The diamond disk is universal, since they can cut off any material. Such nozzles have gained great popularity in the cutting of tiles, stone, concrete and granite. For each material, you can choose your own disk. Some models have a cutting edge with slots, and other solid ones, as well as they come with small or large diamond spraying, depending on the purpose. For example, the discs for cutting stone are solid, and for cutting concrete with transverse slots and small spraying.

In appearance, it is difficult to determine why the disk is intended for, so when buying it is necessary to familiarize yourself with the characteristics of the disk indicated on the packaging.

Polishing and grinding

There are many types of such circles. They can be cloth, spongy, felt and with a change of grinding.

To work with them, it is necessary to use special pastes with small abrasive, as well as various liquids. Small amatery circles are used for stripping and rough grinding. The use of disks for grinding makes it possible to bring the surface of any material to the desired roughness. Such nozzles for corner grinder are used to polish the car body.

These discs can be divided into the following types:

  • Twisted balls.
  • Sharped abrasive.
  • Pitable diamond.
  • Roofed balls are used for peeping stone and metal surfaces when removing the old cement solution or dried paint. Sharoshka consists of two steel cups. Steel wire brushes are located along their perimeter. Depending on the type of processing, the wire may have a different diameter.
  • Sharpenic wheels serve to sharpen the cutting tool, cleaning welds. Most often, such nozzles are used on low.power grinder, since it is more convenient to work with such disks. Speaking disks differ from cutting models in shape and thickness. In the middle part of the disk there is a recess that allows you to sharpen a flat surface of the disk. Its thickness is usually at least 5 mm.
  • Pitable diamond disks in design are similar to sharpening circles. The difference is that the diamond disk works only with its peripheral part, on which there are cutting edges. As well as a diamond roller disk is not suitable for metal processing. It serves for peeling stone, concrete and other similar materials. For the peeling of a frozen cement mortar, a diamond disk is suitable as possible.

The nozzles for corner grinders much increase the functionality of the grinding machine.

Corner grinder is widely used in construction and many other areas. And together with various nozzles, they become universal equipment.

Wood for grinding nozzles

A grinding machine can be used to polish a wooden surface, tree clippings. For this, special types of nozzles are used for certain types of work. Before starting surface processing, it must be marked.

After grinding, circles from the disk remain on the surface. This is noticeable after covering the surface with varnish or paint. This is the peculiarity of the work of the corner grinding. Therefore, it is additionally necessary to walk on the surface with a grinding skin manually. You need to work on wood with a corner grinder carefully, without making great efforts, do not use thin circles, correctly perform their fastening.

To make the right choice of nozzle for corner grinding, consider their specifics and different modifications.

Druming devices

This category includes two types of nozzles.

A hard drive can completely replace a manual rubbish

To perform gross processing of logs during the construction of a house, processing pillars for fencing, such a nozzle will be an indispensable assistant.

The features of its use are:

  • It is allowed to use only with a grinding machine equipped with a second additional handle. For safety reasons, the corner grinder must only be held with two hands.
  • It is allowed to remove the protective casing, since the body of the nozzle is whole, and the probability of its destruction is very small. However, protection against flying chips is required: mittens, glasses, clothes.

How to understand the disks for corner grinding grounds for metal

For high.quality metal cutting, it is not enough to choose a corner grinder, you must still competently choose a disk.

Using various nozzles for corner grinding, you can cut, clean not to polish the metal, in addition, some other materials. Among the variety of metal disks for a corner grinder, to make the right choice is sometimes difficult even to a professional.

This article will help to understand the types of consumables with work.

Classification of interchangeable nozzles angular grinder

For their functional purpose, nozzles for corner grinders are divided into:

  • Cut.off. The most common type of discs used in grinder. They are used to cut materials from various density of non.origin. Circles to perform work with different materials, differ in design not by cutting method.
  • Grinding is not polished. Applying them, the surfaces of the details give mirror smoothness in other words, remove irregularities.
  • Sharpes are not pendant. ?The cut.off circles for corner grinder also tried the intertulovsky disk for giving. Purpose. sharpening the tool is not cleaning parts from paint, rust not other layers.

Cut.off circles

Based on the type of sawed material, several types of cutting consumables are distinguished:

Wood disk for corner grinder, Bosch 125 mm. For cutting metal. Corner grinding wheels (corner grinder) for metal, concrete and. Designed for cutting metal products. Diamond end.grinding cup for concrete for angular grinding grinder Intertool milling mills in concrete Intertool. They differ in thickness not by the external diameter.

The smallest is a cutting disk for an angular grinder one hundred twenty.five mm, and the largest is two hundred thirty mm. The thickness varies from one to 3.4.5 mm. The not just the diameter of the disk, the thicker it is. However, small nozzles have any thickness. This dependence between the diameter is not thick, due to the speed of rotation.

The design is not a way to use such nozzles, are completely identical to the consumables for metal, the difference consists in the abrasive materials used for their manufacture.

Wolf. Work with the use of sawing changing elements according to wood, very dangerous are not fraught with a person to obtain injuries. What are the wheels for corner grinders on wood. This design is a thin metal disk with sharp teeth.

When rotating, it easily and simply cuts wood. However, when it is jammed, an angular grinder can be pulled out of the hands of an employee, under the influence of which he can be injured.

To avoid such incidents, when cutting a tree, it is recommended to follow the following instructions:

  • It is strictly forbidden to remove a protective casing from an angular grinder.
  • You need to use a replaced element with a small tooth.
  • You can not use a powerful feed, since when jamming, the tool will inevitably fly out of hand.
  • If you want to saw wood of large sizes with a powerful corner grinder, special mounts (equipment) should be used for it.

Disk for corner grinder for wood: how to correctly. Diamond disk. It is virtually universal, which can cut materials of any hardness from the softest, to the hardest. Most often, consumables of this type are used in the cutting of reinforced concrete, porcelain tile, and stone not tiles.

For various types of sawed material, diamond disks of various designs are used.

By the design of the cutting edge, there are nozzles:

Drill for corner grinder (corner grinder) on wood Plastic aerated concrete. Safe cutting

Look at my site, find out how just a saw disk for a corner grinder (angular grinder) on wood.

The role of an example is diamond replaceable elements for cutting concrete, which have a cutting edge divided into sectors, not spraying from small diamonds. In contrast to which, discs for stone work, are a continuous circle.

In appearance, it is almost impossible to determine the purpose of the diamond consumable, so in the purchase, you should carefully study the packaging. Another criterion is the number of teeth.

For longitudinal cutting with an angular grinding, a saw wooden disk with a smaller amount is required, for the transverse. Grinding wheels for corner grinders for wood: them. Abrasive circles disk on wood for corner grinders, Bosch 125 mm.

Cut.off, metal circles, an abrasive circle for stainless steel, a cutting circle on aluminum. All information about this tool is displayed here.

Grinding and polishing models

A lot of consumables are produced for corner grinding, allowing you to polish not polish various surfaces.

In the manner of the coverage, discs are divided into:

In addition to its own grinding coating, together with many replaceable materials, it is necessary to use finely amplous pastes.

Gross surface grinding, is carried out when using finely grazed grinding circles. The final polishing is carried out with a cloth or felt nozzle.

Sharp and roller nozzles

For peeling of various surfaces, interchangeable elements of various configurations are available.

Twisted balls. Metal circles for angular grinder are indispensable if desired to clean the surface from the old paint in other words. A twisted ball consists of steel cups, with brushes made of steel wire installed on their edges.

The diameter of the wire depends on the required rigidity of the brush. Idialniya disk for corner grinders drank non.lime teeth on plastic I did not. The tougher the balls, the thicker the wire.

four.5. Sharpits. They serve for rough processing of metal products, such elements of course to clean the welds, as it is also called to tighten the tool.

Buy wheels and circles for corner grinders (corner grinder): prices, characteristics, reviews. To pick up more than 200 software stores and widespread sharpening circles of small diameters.

Since it is more convenient for a small corner grinder to carry out such work.

It is easy to distinguish the sharpening nozzle from the detachment, thanks to a large width (two or more than five mm.) not a deepening on the inside, because of which, of course, to tighten the tool with a flat side of the circle.

How to cut a corner grinder?

Transportation of disks; 2. External disca of the disk; 3. The diameter of the circle must correspond to the permissible corner grinder; four. Compliance with the maximum permissible revolutions; 5. Use of the disk for its intended purpose; 6. The use of a “non.fresh” disk is not acceptable; 7. Inspection of the workplace; eight. Hanging parts of workwear; 9. Position with a cut; ten. Provide for the rebound of the tool; eleven. Direction of rotation of the disk; 12. Try not to deepen the edge into the depths of the cut; 13. Adhere to a given trajectory of disk rotation; fourteen. Turn off the corner grinder when changing the position; fifteen. When changing the disk, de.energize the corner grinder; 16. Grind only the disk provided for this; 17. Use a protective casing when working; eighteen. When working with a corner grinder, always be with glasses.

Consider each of the listed points, and remember that each of them is important at least the other.

Transportation of disks.

Typically, the entire tool is in one box, without fail, take a separate compartment for disks that does not allow strikes on them. Which can lead to damage not noticeable by eye.

External disk examination.

Before installing, make an attentive visual examination of the disk for the presence of a broken, you can slightly beg, and if it is broken, it will immediately be revealed, of course, such a disk is not allowed to use. If there are potholes on the cutting edge, it is better to reject, the cost of the disk is penny, and the consequences can be the most deplorable.

The diameter of the circle must match the permissible corner grinder.

The corner grinder indicates the maximum allowable diameter of the circle used. Never set a circle more than indicated in this meaning.

Compliance with the maximum permissible revolutions.

Both on the corner grinder, and on the very cut.out circle, there is a marking pointing to the maximum permissible turnover per minute. On a corner grinder, this is the value of the spindle rotation, on a circle. at what maximum speed it can rotate. In the first picture, the result of non.compliance with this rule. That is, if the forty rotation of the spindle is 10,000 rpm, then the circle should be equal or large, but in no case no less.

Using the disk as intended.

What is meant here? The fact that the disk intended for cutting metal is not permissible for cutting stone, glass, marble, tiles, porcelain tiles, for this there are special discs with diamond tips on the teeth. And vice versa, a diamond disk is not permissible to cut a metal pipe. It is also not permissible to install various mills on the corner grinder, saws. a visual consequence in this picture: and in a conditionally named second picture, the man sawed the tiles with a cutting disk for metal, in addition, without a casing. I don’t do tile work, so I don’t know what speed of rotation of the cutting disk should be when cutting the tile, on the forum one of the specialists indicated that no more than 3000 rpm, and by itself a special disk for this. What led to an unfortunate man who was neglected by this rule themselves.

It is not acceptable to use the “non.fresh” disk.

What does that mean? I found, for example, a disk in a garage or under the bathroom, or where. break it and throw it out, that’s the whole fairytale, not to jerk fate for anything!

Inspection of the workplace.

Also not unimportant nuance, cutting out pipes in the apartment of workplaces, in the toilet, in the bathroom, in the kitchen. Inspect the first. PARTOVO for the absence of hanging wires, ropes. It is no secret that people like to be tied to pipes, so you need to remove it away from sin, you will be intact. Some kind of crap for a rotating element of a corner grinder, it will fly out of her hands and you won’t have time to blink.

Hanging parts of workwear.

I think it’s not worth it to explain what can be fraught with. The buttons are fastened, the holes are sewn up, the fringe on the legs, no sleeves.

Position with a cut.

Clear stump, when dismantling, you try to get by the least amount of cuts, but never, you hear never being on the trajectory of the disk, no matter what you are, you will not provide for everything, there are all sorts of cases. The next point to the place.

Provide the rebound of the tool.

Just in case, provide where the tool can fly off if it “bites” the disk. And if you are not sure, do not do the cut to the end (the pipes are often in suspense), leave a small jumper, you can always break the gas key with the help of a gas key. Do not relax, at the end of the cut, hold the corner grinder tight.

Direction of the disk.

Who cuts like, a matter of habit, and sometimes otherwise there is no way. The video clearly shows that I cut. sparks on myself. This is not very convenient, but there is much less likely that the disk will “bite”, and if it “bites”, then the corner grinder will fly from the cutter, and not on it. So think about the amenities in this case.

Try not to deepen the edge into the depths of the cut.

Well, here regarding the pipes of large diameter, do not deepen the cutting edge more than necessary, less likely that the disk will break.

Hold the specified drive trajectory of disk.

This condition is unequivocal to execution, no changes in the trajectory of rotation, that is, how to cut, in the same position it is necessary to finish the cut. And one more point, if there is no professional skill, you should not try to get into an unfinished car for a second time, and in no case do not insert a disk and then turn on the “start”, don’t go straight to the grandmother. the saddle is waiting.

Disconnect the corner grinder when changing the position.

I made a cut, you need to change your position, turn off the corner grinder, wait for the stopping of the disk rotation, only then move. Took a different position, made, turn on the angular grinder. This is the only way, not otherwise. If health is expensive, otherwise you can stumble.

When changing the disk, de.energize the corner grinder.

Be sure to remove the fork from the outlet, install another disk. It is not appropriate to be lazy here.

Grind only the disk provided for this.

To cut the threads, it is necessary to remove the chamfer along the edge of the pipe, often “slop” to install the grinding circle provided for this, and in vain, pulling it with a cut.out circle, you will become thinner, which is not good, fraught with the same “vulgarity” for pieces.

How to cut pvc pipes

When working with PVC pipes, it is often required to cut them. One of the advantages of PVC is that they are easy to cut with a wide variety of tools, which relatively simplifies the work. For pvc cutting, you will not need special devices or complex tools. To cope with the task well, you can use various tools, including hacksaws, pipelines and end saws.

  • Also, instead of a vise, you can use another type of clamping device to fix the pipe in a certain place on your workbench. Use what is available.
  • So that you have a sufficient gap, clamp it a few centimeters from the cut. If possible, you can clamp on both sides of the cut, but holding one side a few centimeters from the line of the alleged section will make it completely safe.

Make a mark where you need to cut. With the help of a permanent marker, clearly indicate where you are going to cut the pipe. Do not worry that the ink will remain, later you can wipe them with medical alcohol if the appearance is so important.

Put a hacksaw with teeth to the pipe. Place the hacksaw on the mark and hold the handle tightly, then with the help of the other hand press on the upper part of the hacksaw, pressing its teeth into the pipe. You need to start sawing from the right place in order to avoid extra unnecessary backwater.

Sew the pipe confidently. Start the cut, carefully following the process so that the hacksaw does not go from the mark that you put on the pipe initially. Drink quickly enough so that the incision is deepened, but not so much that the teeth jumping the cut that you perform. You must be able to cut PVC relatively quickly.

  • Sometimes, for the use of scissors type pipelines, extremely strong hands are needed and it would be easier to use a saw of any type. The acquisition of a locking.type cutter will greatly facilitate your work.

Place the pipe in the lower part of the pipeline made in the form of a crescent. To insert a pipe into it, the pipeline has an open rounded edge, and when you press the button on its handle, the blade comes out from there. Mark the desired section of the cut, then to start the section, insert the pipe into the receiving opening of the pipeline.

Pull the blade on the pipe. To get a blade, press the trigger handle on the pipeline handle and cut the pipe in half. For stability when cutting, hold the pipe with the other hand. You should not be overstrained at the same time.

Consider the use of the User and saw for more accurate cuts. The saw can be used for PVC products when you need to perform many specific, small cuts. Use a dentate saw suitable for the section of the section and based on the availability of endings. If in doubt, select a standard wooden blade size of 10 teeth 2.5 cm, which is found in most endings. Although, this will depend on a particular brand and the type of a purchased saw.

Place the PVC pipe under the blade in the right place of the cut. Speed ​​is the easiest way to use in the world, since when it is used to use a fishing line for a cutting trimmer for your convenience, it will be previously noted next to it. You cannot miss.

Fasten the pipe using a clamping device. Run the blade and reduce the speed to the average. Upon completion of the cut, the process can be easily repeated, when necessary, performing additional cuts.

Scabble for metal.

The most common way. The only drawback. The cut can turn out to be a curve to avoid this, it is advisable not to saw immediately, but to turn the pipe 3-6 times. It will look approximately like this:


The fastest and most convenient way after scissors. But the cut can also turn out a little oblique on sewer pipes with a diameter of 50 mm. Here it is also desirable not to cut right away, but turn the pipe 2-3 times. If you need to saw off the pipe with a diameter of 100 mm or more, then first you need to drill a thin drill (2.5-3 mm) a number of holes to insert a jig.

This method is suitable only for thick.walled water pipes.

If the cut is still not very even or not straight, the end of the pipe can be treated with a grinding skin. And at the end of the sewer pipe for better docking you need to remove the chamfer, this can be done with a knife, but it is more convenient for the same grinding skin.

Conclusions and useful videos

The video presents calculations and shows a workshop on performing a cut of the pipe at angles 45º and 90º:

For each individual installation case, you can choose the most convenient and less costly method of cutting. The specific choice depends on the material of the pipe, its diameter, wall thickness.

Using simple marking methods, you can get a fairly accurate angle under which you need to cut the workpiece. At the same time, referring to a complex calculation methodology, it is possible to cut at non.standard angles with high accuracy.

How to cut metal.plastic pipes correctly?

Cutting metal.plastic pipes requires experience. Only after cutting several tens of meters of material in the hands does confidence appear, and the movements are brought to automatism.

In the case of cutting pipes, the golden rule applies: “measure 7 times, cut 1 time”. It is better to spend the extra 30 seconds on checking the accuracy of the mark than to spoil the material with an incorrect cut

To get two from one pipe, you need to perform consistent operations:

  • Make a mark where a cut should be made. It is important that the mark is strictly across the pipe, and not at an angle. Then the blade will pass perpendicular.
  • Fix the pipe using a clip of pipeline. Some models capture the part with a spring, others are installed by lowering the rod, and in the third you just need to lay the material, and you will need to hold it with your hands.
  • Make sure that the mark strictly coincides with the blade. If this is a roller pipeline, it makes sense to conduct the first turnover of the tool to check the accuracy of the installation.
  • Cut the pipe: click the ends of the knot handle, click on the trigger, lower the roller roller roller roller roller roller roller roller shows. it all depends on the chosen pipeline model.

A distinctive feature of cutting metal.plastic pipes, in comparison with sharp polypropylene products, is that the accuracy in this case is very important. The polypropylene pipeline will be connected using high temperature, the plastic will melt a little and thus hide all possible inaccuracies.

But in the case of metal.plastic pipes, this will not happen. The ends are mounted in special cuffs and each mm of inconsistencies threatens with loose fit and the occurrence of leaks. We brought detailed instructions for the installation of metal.plastic pipes in the next article.

After the cut, you need to blow the resulting segment. The chips of aluminum or plastic, which remained inside the pipe after installing the entire system, can disable equipment that is connected to the pipeline, or cause a blockage to occur.

Conclusions and useful videos

With such a wide range of building tools, both manual and electrical tools choose a pipeline that will cope with its function, but will not cost more than the heating system itself, is a very real task.

Knowing what varieties of devices, as well as having become acquainted with the most popular models, you can easily choose and buy equipment for working with metal.plastic pipes.

Write your opinion and recommendations under this article, add unique photos of your model of pipe scissors or the cutting process itself.

Than and how you should not cut polypropylene?

In addition to the above specialized pipelines, polypropylene pipes can be cut:

One “but”. The edges of the pipe as a result of using these “improvised” tools are torn. This is not only ugly, but also unacceptable.

Before soldering, the pipe ends must be cleaned from all burrs and leveled, otherwise the connection will turn out to be fragile. Such aggressive cutting almost always leads to problems on a mounted pipeline in the future.

It is not recommended to use corner grinder. Due to the high speed of its disk, the polypropylene pipe will begin to heat up and melt. A similar situation can occur when using an electric lobe, if you turn it on to the entire power.

These tools should be used to cut plastic only in extreme cases, when there is nothing at hand.

If the plastic pipe has to be cut with a hacksaw, then it is necessary to do this by installing it in the knock, it is extremely recommended to cut it on weight, it will be difficult to get an even neat edge

Regardless of the chosen tool, it is impossible to press it on a polypropylene pipe when cutting. This applies to the use of both corner grinders and professional pipelines.

Efforts should be increased gradually, otherwise the plastic can simply crack. With severe pressure in the pipe walls from PP, invisible to the eye of the destruction, which will then lead to a gust of pipeline.

There is another argument against a strong pressure of the cutting tool on a pipe made of polypropylene. deformation in terms of geometry. The walls in the place of such pressure begin to remember, which is why the cut in the cross section from the circle turns into an oval. And the end of the welding with fitting should be perfectly round. Then you have to straighten it with a calibrator, which will require time and effort.

In order to prevent the bending of the walls, a couple of round bars of wood of slightly smaller diameter should be inserted into the cut pipe. The knife will have to pass between them when cutting polypropylene. So the plastic will definitely not bend, but will be spread as it should.

It is categorically not to use a strip saw or circular for cutting. Polypropylene is too soft and at the same time too fragile for them. On the one hand, the pipe can be pulled out of the hands, and on the other, without chips and cracks at the site of the cut, it will definitely not cost here.

It is also not recommended to use pipelines intended for pipes from metals. Their knives are made of other material with slightly different characteristics.

They will not cut plastic, but tear. The exception is only universal tools for all types of pipelines. But they cost a lot, this is more option for professional plumbers.

The choice of pipeline. mechanical VS electric

In everyday life, it is recommended to use a manual cutting tool for one.time work. It costs cheaper than electric and easier to use it.

If you need to make several cuts to install the water supply in a private house or apartment on a site from a riser to any plumbing, then this is just the perfect choice. However, with large volumes of effort and time to cutting the pipes, a lot will take them.

Hand pipelines are driven exclusively due to the muscle strength of the installer. if the plans are independent of the independent installation of long pipelines in the cottage, then it is worth acquiring a power tool

Electric equipment will cost more than a mechanical analogue. But it greatly facilitates and accelerates the process of cutting polypropylene pipes. The edges as a result are more even. There is no need to apply efforts to press the handle in this case, you just need to keep an electric pipeline exactly along the cutting line. Errors are practically excluded.

Any power tool for work requires food. If the problems (electricity to the newly erected house have not yet been connected or accidents are constantly taking place), then it is better to prefer a manual pipeline. We will have to work hard and attach strength, but the installation of the water supply and sewage will be executed on time without delay.

Manual pipeline has compact dimensions. Often a bulky electric counterpart to bring to an already mounted pipeline to make a note into it, it is simply impossible. But with hand scissors to perform such a cut will turn out without problems.

An alternative to both of these pipeline options is electrical equipment with a removable battery. A similar tool weighs only 1.5–2 kg. The electric drive facilitates the cutting process, but the socket for connecting such “scissors” does not have to look. The battery usually has enough of a couple of hundred cuts, which is enough for a full working day.

How to cut plastic pipes for the water supply: options

To figure out how to cut plastic pipes for water supply and sewage, you must understand what materials they are made of. That is, by and large you can answer immediately-it will be a hacksaw for metal, a sharp knife, an angular grinder with a cutting disk or a pipe scissors. But each individual case is fraught with certain nuances that you need to know even an amateur plumbing.

For a water supply, sewage and heating in the sanitary product market, you can find several types of polymer pipes:

  • Polyvinyl chloride pipes known as PVC.
  • Metal.plastic flexible pipes with reinforcement.
  • Pipe from stitched polyethylene for water supply and heating.
  • Polypropylene pipes with and without reinforcement.

PVC pipes. how to cut them

Polyvinyl chloride pipes, known as PVC can have a diameter of 50 to 400 mm, mainly used for sewage and ventilation. Polyvinyl chloride pipes relate to materials designed for low pressure, but have rather hard walls. For small diameters as a cutting tool, as a rule, a hacksaw for metal is used (diameter no more than 200 mm). In this case, a universal cutter can be called a corner grinder with a cutting disk for metal (as an exception, you can use the concrete disk with winning segments or diamond spraying). If you need to cut the pipe more than Ø 200 mm, but there is no way to connect to ≈220 V, then again it is done with a hacksaw, cutting off the workpiece in a circle.

In order for the cut end to the pipe to have 90 °, the fishing line for the trimmer cut is outlined by a marker. this helps to adhere to a right angle and not go aside. The cut, as a rule, turns out to be torn. melted pieces of plastic chips will stick out in different directions and will not allow you to insert the pipe into the bell through a sealing ring or rubber reduction. Therefore, the cut should be cleaned with a knife, and sometimes it is even necessary to make an external chamfer. this is relevant in cases where fittings and pipes from different manufacturers.

Metal.plastic flexible pipes with reinforcement

Now we will figure out how to properly cut plastic pipes with reinforcement, known as metal.plast. The image at the top shows two metal.plast bays. these are composite material made of polyethylene, aluminum foil and glue (there are manufacturers who do not use glue, but in this case, it does not matter). Diameters from 16 to 32 mm are used in household needs, which allows you to fragment them with a hacksaw for metal, corner grinding with a small disk, knife or plumbing pipe scissors.

Despite the fact that you can use any of the above cutting tools, there is still a difference, and significant. All these cutters, with the exception of corner grinders and hacksaws for metal, are very pressed against the walls during fragmentation, and the pipe is flattened. This suggests that further manipulations with metal.plast can only be done after cutting the cut with a special tool. For experienced plumbers, this procedure means delay for only a few seconds, but for beginners in such situations it is best to cost a corner grinder or a hacksaw for metal. After circumcision on the plastic, there are burrs that need to be scrape (do not cut!) with a knife.

They are very similar to metal-plast in the appearance and structure of the walls of the pipe PEX-A, PEX-B and PEX-C, but there is sewn polyethylene and reinforcement have a slightly different quality. Since we are now not talking about the technical characteristics of water pipes, we simply limit ourselves to the fact that the conditions for cutting PEX remain exactly the same as for the usual metal.plastic.

Pipe from stitched polyethylene for water supply and heating

Now let’s fire about the same stitched polyethylene, only without reinforcement. In this situation, the pipes have a characteristic feature of restoring the form after damage. This means that if such a pipe is cut with a knife or scissors-pipe cutters, after flattening it will take a characteristic rounded shape. In fact, in this case, any of the tools that was mentioned above is suitable as a cutter. But for a beautiful, even angle, it is better to cut the place of fragmentation with a marker.

Polypropylene pipes

It should be understood that PPR pipes differ not only in diameter, but also in the structure of the walls. So, the marking PPR PN10 and PN16 indicates the lack of reinforcement, and the marking PN20 and PN25 suggests that the pipe is reinforced with aluminum foil or fiberglass. For cutting polypropylene pipes, as a rule, they use pipe scissors, which are sold complete with a soldering iron for PPR, and they can also be bought separately. But we should not forget that the capabilities of the scissors are limited by the diameter of the PPR and they are usually used for pipes not thicker than 40 mm.

On an industrial scale, gas pipelines with a diameter of up to 1600 mm are laid and, of course, there can be no way to do with scissors or corner grinder with a trimmed disk. Therefore, the cutting of polypropylene pipes of large diameter is performed by a special pipeline. For example, for one.time cutting, scissors with a chain drive are most often used, as in the upper photo, but for laying industrial pipelines, it is undoubtedly better to use cutting tools with electric.
