How easy and quickly cut the thread with a dwarf

The fact is that on sale today there are two main types of this tool. details in the table below.

However, the price of such a device is quite high, and objectively, then the power tool is intended for professional activities. That is, for one.time work, it is simply impractical to buy it.

So, it turns out that if you need a one.time cutting on the pipe Klupp, it is more profitable to purchase a hand tool. Let’s look at what to pay attention to.

Why is the device intended

Most often, home craftsmen acquire a dwarf to create carvings on pipes. If you do not know where and how to cut the carvings of Klupp, then the tool is used to solve the following problems:

  • Cutting threads on the pipe frame of prefabricated structures. It can be racks, garage shelves, greenhouses or greenhouses, arbors or garden pavilions, benches and chairs, tables.
  • When assembling the internal system of pipeline supply of water in the hot water, CVS from galvanized pipelines, pipe from alloys and stainless steel.
  • When installing heating systems on the same pipes for joining and joining cast iron, bimetallic, aluminum or steel radiators.
  • When constructing an internal gas pipeline at home.
  • When working with nodes and elements of home.made devices and metal equipment, as well as with thick.minded PP or PNDs.
  • In tanks to create threads on internal highways or on drainage tracks.
  • When drilling a well on the site. to combine drill rods.

Inexpensive dwarfs are sold in manual or electric versions.

The choice of tools

We note in advance that you can cut the thread in different ways. You can work both manually and machine. In the first case, as we have already noted above, it is necessary to have a set of tools for creating threads, in the second work they work on a lathe. It is recommended to cut the thread manually if your task is to process only a few parts. For example, when assembling plumbing equipment, the creation of household pipelines and t.D.

The processing of parts on a lathe implies the performance of large.scale tasks. A person with experience on equipment of this type is able to cut the thread on an industrial scale, up to hundreds of parts per hour, and sometimes more. However, you are unlikely to need such performance.

Most often, a set of hand tools covers all the everyday needs of home craftsmen. With their help, you will also be able to cut the thread correctly and efficiently, only time and effort will leave more.

The set of equipment mentioned above is mainly represented by taps and dies, as well as various additional details.

Features of taps

Taps are called cone.shaped or cylindrical details, which are designed to cut internal threads. In particular, with their help, threads are performed on pipes, nuts, small washers, various kinds of clamps and even flanks.

It is quite convenient to use taps. They consist of the working and back. The working part has a unique shape and diameter. Special incisors or teeth with some step are applied at its edges. The teeth during rotation cut the metal in parallel with the removal of the chips.

The back side is made in a certain form, which facilitates the fixation of the tap on the working tool.

A variety of taps for domestic use

Taps with the possibility of cutting threads without shavings are also used, but much less often, because they are more expensive.

Blacks perform the first passage, remove most chips and form rough grooves for the thread. This is not a full.fledged thread, but the preparation has already been completed. models are extremely rare. They are intended for finishing the rough grooves, cleaning them and forming the workpiece for clean thread. taps are used mainly in the manufacture of complex parts.

The last sample is a final tap, forms a threaded thread of exact sizes and shapes ready for operation.

By the type of action performed, taps are divided into:

Note that with taps, as well as dies, you can cut the thread of different sizes, directions and shapes. It all depends on the selected equipment model.

Features of the dies

The dick is called the cutting tool, which is used in the external thread. The simplest example of the presence of an external thread is a bolt. While an example of internal carving is a nut.

The dies are flat, from the side they strongly resemble large goals or clamps for machine cartridges. Only inside the dick is a cutting nozzle with several rows of twisted incisors.

threads, design

Dies can have different shape, type of assembly and dimensions. There are both round models and square. Some options are completely whole, others can be disassembled and replaced by the cutting nozzle.

The cutting part consists of three working zones. Two zones that are located at the edges consist of teeth, while the internal zone is responsible for the removal of chips and adjusting the direction of rotation.

It is thanks to the inner zone that the dicks have a self.tightening property. That is, after several rotations on the pipe, the plug is fixed.

Then it can be rotated without pressure, since it will be delayed in the direction of carving formation. While taps must be rotated with effort throughout the process.

Varieties of dies, in fact, are similar to varieties of taps. If you bought a large set of tools, you will surely get several such details at once.

I cut the thread on the pipe Lerka, or Klupp.

To cut the thread on a pipe with a diameter of 15 (it is 1/2 ″, it is half a inch), I usually use the leerka in the lurk holder, which I put on the prepared cut of the pipe, the side that has the edges, due to its length, it plays the role of the guide, What is important for a uniform hook Lerke. I slightly crush my hand to the end and rotate behind the intelligent key, clockwise

It is not always possible to use the guide side, this is due to the fact that the cut of the pipe for some reason is made very close to the insert into the riser, then you do the entry from the side of Lerki. In this case, you need to be more attentive, hold the Lerk perpendicular to the axis of the pipe, otherwise the thread can go crookedly and will plug the pipe through the fourth on the fourth. Actually, if the chamfer was removed throughout the diameter evenly, then the entry will go evenly, respectively, and the whole thread.

You can cut the thread and the dwarf, but usually the pipe of this diameter is used on the wiring, and it is not possible to use the cake due to massiveness.

On a pipe with a diameter of 20 (she is 3/4 ″, it is three quarters of an inches), I cut the thread with a klipp, although just in case I have a three.quarter lurk in the lurk holder. Out of the same considerations as in the above paragraph.

And pipes with a diameter of 25 (it is 1 ″, it is also an inch) and with a diameter of 32 (it is 1 1/4 ″. She is also inch with a quarter), I cut only ducks with a screw-trip. This is due exclusively with the complexity of this work. Using the dwarfs, the process is much simplified, facilitated and accelerated.

In the photo, in addition to Lerki and Klippov with the Gate, he imagined that I use a threaded connection for the tightness of the thread, namely, a universal, plumbing sealant and plumbing linen. After I cut the thread, I put the sealant on it, trying to distribute evenly on all the turns, and after that I wind the lin, I tell (and show) in another article, I will leave the link below.

Compounds are not only threaded.

In my profession, it is necessary to connect polypropylene with cast iron, when installing sewage. Basically, this compound is carried out by means of a transition rubber cuff, which you insert into a sealant, you insert a cast.iron pipe or fitting into the bell, and already insert a fitting or polypropylene pipe that is smeared with sealant into it. Due to this, the compound is hermetic.

The photo shows a helicopter, different in thickness, it is also used when installing a sewage system, by ramms into a gap between the above materials described. The use of the hood is convenient in that you can dissolve it and choose a strand of the required thickness. Its use is relevant in the case when the transition cuff is not suitable in size, such cases are not frequent, but still meet.

Use of Klipp

Cutting Klupp is a modification of a conventional dick, equipped with an additional device for organizing a direction and rattle, in order to simplify the cutting method. The KUPP market is usually offered in the form of a set of tools for cutting threads.

When using Klipp, it is necessary to act in this order:

how to use thread command in solidworks

one.install in the ratchet rifled KUPP the diameter selected from the set; 2.Process with lubricant chopped and cutting parts of the pipe and dwarf; 3.put on a device for the direction of Kulapp (guide) to the end; four.rotating the rattle clockwise, cut all the steps of the thread; 5.In the process of rotation of the device, continue to lubricate the trimmed and cutting parts of the pipe and Klupp.

The causes of defects. How to avoid defective products?

The condition for marriage when cutting may be non.compliance with one of the following rules:

one.The diameter of the processed pipe must correspond to the diameter of the manufactured thread; 2.use only good devices sharpened, clearly specified; 3.It is necessary to lubricate the product and the device with machine oil (special fluid for thread) both before cutting the thread and during operation; experienced specialist should perform work.

It can be concluded that for reliable and dense connection of various plumbing equipment to tubular water supply, heating or sewage systems, as well as pipes among themselves, it is necessary to adhere to the rules described above, with strict execution of which the probability of defects is significantly reduced. To facilitate the implementation of these rules, it is recommended to have a set of special tools for cutting.

Hand Clipp

Hand.handed pipe carving. the usual tool of plumbers and plumber. They can cut a new one or drive away the existing thread when installing or repairing the pipeline in the apartment and in the country, basement or well. Unlike a classic dick, Klupp allows you to do this work in uncomfortable and inaccessible places.

The disadvantage of the manual dwarf can be considered quite great efforts on the handles. With standard housing and communal pipelines ½ and ¾ inch threads, you can cope without special skills, with large diameters of time for cutting, it can be significantly and disproportionately larger. Accordingly, the effort increases the force of the handle or rattle lever, therefore, with diameters above one or one and a half inches, manual ducks are practically not used.


Revobona.stringed dicks are divided into the following categories:

The former are designed, as a rule, for pipes of small diameter. They are equipped with a long handle or involve the use of a divorce or suitable on a caliber of an ore key. Such a tool is simply put on the pipe and twisted with a key. Plumbers value simple manual dwarfs for taking up little space in the bag. But cut the thread on a caliber pipe with a more inch with such a device is a very time.consuming process.

In this case, their counterparts with “rattles” handles come to the rescue. You can use a universal universal “loot” key. When moving in one direction (say, clockwork), he fixes the dwarf, like an ordinary nut, twisting it. In the opposite direction, the lever moves freely, thus the thread is cut by reciprocating movements, which consumes less strength.

Such devices are convenient when installing parts of the pipeline near the wall itself, where it is impossible to rotate the handle in a circle.

Professionals for the sake of saving effort and time prefer to use automatic electric circups, outwardly similar to a corner grinder, in which the gearbox is modified in a pipe holder and a dick. The kit usually includes several collapsible dies of different calibers. In fact, the price of the entire set depends on their number. In addition, the kit should include a special clamp, which allows you to fix the device on the table or workbench.

The principle of cutting threads on different types of surfaces

Algorithm for applying threaded turns on pipes:

  • If the pipe is not new and has already been in operation, it is necessary to clean it of dirt or paint;
  • fix the pipe motionless;
  • in the place that will be processed, apply olifa or oil;
  • put on a dwarf on the pipe, turning the locking screws at the same time;
  • reduce the guide dies close to the pipe, gently hitting the handle of the clamping ring with a light hammer with a light hammer;
  • consolidate guide guests with a locking screw;
  • In the same way, install and fix the cutting dies, focusing on the cutting of the required diameter of the chopped pipe;
  • Clutching the dwarfs forward, rotate it clockwise;
  • It is recommended to cut threads gradually, without jerking, slowly, making a stop after half a turn so as not to bend the pipe;
  • To remove the dwarf from the pipe of the dick, it is necessary to dilute.

After the manufacture of turns, you must try to combine the made thread with the return part. You can continue work only in the case of proper interaction of elements. In the case of processing the old pipe, the chopped thread should be examined for the presence of through slots. If the cutting is applied to a worn tap pipe, it should be held by a gas key so that the force applied during the rotation of the dwarf is reimbursed.

Manual threaded.cutting dwarfs, like every tool, requires constant care. The long service life is ensured only in case of proper use of the mechanism. Therefore, after operation, it must be disassembled, cleaned of contaminants and lubricated. At the first signs of the cuts of the incisors, they must be changed to other form and sizes.

Inner appearance

Cut the inner thread on the pipe with a special rod called a tap. He, in turn, is inserted into a special cart. The tap consists of the front (fence) part, which is located at its end, the calibrating part (middle of the head) and the tail of a square profile for normal retention in the device.

I must say that when crossing the metric system to the inch, three types of taps must be used, which are cut at different depths.

The technology of cutting internal threads involves the following sequence:

  • The tap needs to be selected by the step of the cut on the element, which will be screwed into the pipe.
  • Next, the tap is inserted into the cart;
  • The tap is exposed strictly along the longitudinal axis of the pipe so that everything is cut smoothly and without bevels;
  • Clutching an element for cutting together and the end of the tap need to scroll the cart;
  • Cutting is made to a marked depth with a small margin.

The process itself is much better to be performed on the machine, where the tap is inserted into a three.cubic cartridge, and the element in which the cut will be made is fixed on the mobile bed. In this case, the exact coincidence of the axes is guaranteed. Manually this is much more difficult to do. But if the connection is not very responsible, then you can not bother.


Due to the simple design, manual sets of dwarfs for cutting threads are reliable. All their elements are made of durable metal, which withstands significant physical activity.

Compared to electric counterparts, this equipment is characterized by smaller dimensions, mass and most importantly, it allows you to work where there is no electricity or its use is not recommended or even dangerous! Such a dwarf is perfect for creating threads in, slagged places.

As a rule, pipe manual threaded.cutting circuits are offered in sets, which is especially convenient when conducting installation and repair work on pipes of different diameters.


A tap- a tool for cutting the internal thread, is a bolt of tool metal, with formed cutting edges and chips.For the manufacture of internal threads in viscous materials, several taps (2-5) can be used, which differ in the height of the profile (to reduce the cutting force).Taps for cutting threads in through and deaf holes, have constructive differences (in taps for deaf holes, the entry part is shorter).Modern taps are made of high.speed steel or solid alloy.In plastic metals, it is possible to form a thread by plastic deformation, without cutting, respectively, such taps are called rolleries.Tap is the main tool for cutting the internal holes manually.To reduce friction and prevent the tap jacket, its thread is performed with reverse cone (tagging).

In the market, in a universal store or a network supermarket, you can find a tool with any name, including copied, similar and consonant with any of those given and similar. It is also impossible to turn away from such a product also, in plain packaging, a very high.quality contents may contain a very high.quality.

We have very well figured out what is a tool with such an unusual name. KUPP. In addition, we also examined how to choose it and how to use it. We hope that all the information published above will be useful to you in the case.

Well, if you want to know more about this device, then pay attention to the video in this article.

Despite the fact that there are no locksmith skills, you can cut the thread with your own hands. For this, special devices are used, through which the work is performed in a matter of minutes. When repairing the water supply, the issue of fixing the products often arises. In this case, the dwarf is used. the tool with which the thread is cut.

How to cut an internal thread?

In some cases, an internal thread is required, which can also be cut when using a hand tool. Often, a tap is selected for such work, which consists of three main parts:

The fence is used directly at the time of cutting, the caliber directs the tool and ensures its vertical position. The tail is required in order to fix the dick in a special holder.

The internal thread can be formed as follows:

  • The pipe is fixed in an upright position.
  • Temor processed workpiece are lubricated.
  • The device is placed strictly vertically, after which several rotations are made clockwise, and one against.

At the time of operation, add oil from time to time. Due to this, a smooth course of the tool is ensured.


There are two options for applying pipe pipe depending on their position, which can be motionless in various technical structures, building facilities, and mobile, placed in a clamping tool. In the latter case, a vice is often used, the disadvantages of which include the possibility of damage to the surface and deformation of the shape of the parts.

Leading world manufacturers produce special nipple clamps with an extensor headstand, which is inserted into the pipe. During the rotation of the rod associated with the extensor, the head increases in volume and is reliably pressed against the internal pipe walls, while not the part is fixed in the vice, but the clamping nipple itself.

Threading operations on transported pipes by means of Klipp are carried out in the following sequence:

  • Cut the pipe at right angles, trying not to leave the burrs. To accurately withstand the angle of 90 degrees, wrap the shell in the place of the part with a tape from any adhesive material or a fixed strip of paper before combining the ends, after which they cut the workpiece exactly along the edge of the template.
  • Fix the part in a vice, leaving a free end of about 100 mm, apply a special oil from the cylinder on the edge and put on the workpiece of the curtain leerka, pre.placed in the ratchet mechanism.
  • Pulled out and rotate the stagnant finger of the ratchet to the working position in the arrow.
  • Press on the circus nozzle on the side and begin a slow rotation of the device with regular supply of oil to the working area. During the work, only special branded oil is used, which washes off the chips, and does not stick it to the turns, worsening the quality of the cut.
  • They continue to rotate the rattle until the Lerks find themselves in the same plane with a pipe end. this is the standard length of conical thread.
  • After the passage, they rearrange the stopped finger at the arrow in the position of the reverse and rotate the head in the opposite direction, completely twisting, after which the cutting is ready for work.

The advantages of Kulapp in front of a simple dick

The dice is made of expensive instrumental steel. over, only incisors should be especially durable, because it is they who form the thread. And Klupp, as we have already noted earlier, is also a dick, but without expensive and non.functional elements. Inexpensive holder, as well as durable incisors. that’s all that is required in this case.

It would seem that it is illogical to consider the tool as a budget alternative to the dick: on the market you can find ducks, the cost of which is measured by thousands of dollars. But do not forget that inconsistent inconsistent elements.

What is the savings at all? On consumables. As for the tool, its cost is so high for the reason that it makes the process of cutting the thread less tedious and more convenient.
