What Is The Difference Between A Circular Saw And A Circular Saw

3 signs of a good circular saw for metal About how the circular saw for metal differs from its counterparts, according to what criteria it is classified, how much it costs and what tasks it performs, let’s talk further.

Classification of circular saws

The second criterion is the cutting depth, again determined by the size of the blade. So circular saws are divided into 3 groups:

4 to 5 cm (sheet metal cutting);
From 5 to 7 cm (cutting metal, profiles, small pipes);
From 7 to 14 cm (professional equipment for bulky or thick materials).

The third classification criterion is the power of the instrument. There are also 3 groups (for household work, universal and professional models):

Up to 800 W;
800-1200 W;
More than 1200 watts.

All models, regardless of power, allow cutting workpieces from both sides. Sometimes it is not possible to cut straight away, so a circular saw is suitable for thick workpieces.

The fourth criterion is disk rotation speed. For household models, the indicator is about 3000 rpm, for professional models it exceeds 5000 rpm.

In addition to the listed criteria, there are geared and gearless devices. The former have a transmission between the electric motor and a six-speed gearbox, while the saw blade is on the shaft of the latter. In the latter, the toothed blade is fixed immediately on the motor shaft. The advantages of gear models are the ability to adjust the cutting depth, blade tilt. The advantages of gearless circulars are compactness, lower weight and cost.

Another classification criterion is the way the saw is positioned in the workplace. There are stationary circulars mounted on a fixed bed. This makes it possible to cut long or wide material. Examples of devices EinHell TC-TS 2025 U, Hitachi C-10 RE, domestic Spec SRS-2000. The cheapest models cost 13-17 thousand rubles.

The many differences between some saws and others make it difficult to choose the right model. Further advice will be given on choosing, as well as some models of circular saws for metal will be considered.

Tool features

Circular saws are a type of circular saws. It is used for cutting metal sheets, rods, pipes, fittings. Powered by an electric motor. The tool is submersible, that is, it cuts metal not only from the edge of the material, but from an arbitrary point.

The design of the product is such that it can be easily disassembled when replacement or maintenance of parts is required. The only item requiring regular replacement is the cutting disc. It is made of tungsten-doped alloy steel. Although the need to change the disk is dictated by the frequency and intensity of work.

What Is The Difference Between A Circular Saw And A Circular Saw

The introduction of an electric motor and the ability to replace the reciprocating motion of the cutting blade with a circular one decades ago made the circular saw for metal a kind of innovation. Today, a powerful mobile device has overshadowed well-known analogs like a hand-held hacksaw.

Manufacturers produce models for the right or left hand. Some models are universal, that is, the user independently chooses on which side the handle is located. Circular saws are used in many areas of production, construction, as well as household needs. Equipment is selected according to a number of criteria for specific purposes.

3 signs of a good metal circular

About how the circular saw for metal differs from its counterparts, by what criteria it is classified, how much it costs and what tasks it performs, let’s talk further.

Among the equipment that allows you to cut metal, the circular saw stands apart. According to the principle of operation, it resembles a grinder, only the working element is not an abrasive, but a toothed disc. Further, what is the difference between a circular saw for metal and analogs, by what criteria it is classified, how much it costs and what tasks it performs.

Equipment selection criteria

Power. The parameter is largely influenced by the size of the saw blade. The larger the diameter, the higher the power and the more productive the tool. For household purposes, a network device with a power of up to 800 W and a price of no more than 8 thousand rubles is suitable. (for example, Skil 5330 LA or Sturm! CS 5060 MS), for regular professional work from 1500 W (Kolner KCS 190 / 1900T for 5000 rubles).
The ability to adjust the intensity of turns. A tool with this function will accurately cut metal of any thickness, since the speed of rotation of the disc can be increased or decreased. Example Bosch GKS 55 GCE for 20-22 tr.
Cutting depth. Models with an indicator up to 50 mm will cost 5-12 thousand rubles. (Makita HS 201 DWAE), from 50 to 100 mm, depending on the manufacturer (Evolution Rage-230 with a cutting depth of 84 mm for 32,000, Interskol DP 190/1600 M from 6 thousand rubles), over 100 mm for higher prices (for example, Makita 5143 R, 130 mm, for 45-50 tr., Messer CS 320 with the same indicator, 52-54 tr.).

Stationary models are much more expensive than manual ones, although they cannot be said to be more versatile. However, for small household chores, it makes no sense to buy a bulky frame with a saw at a price of 50 thousand rubles, when you can get by with a manual analog for 5-7 thousand.
Finding good equipment at a bargain price is easy if you follow the recommendations above. The variety of circular saw blades allows you to find a tool for any wallet. The considered equipment for cutting metal is much more efficient than grinders, so it makes sense to overpay a little and never worry about the possibility of damage to the workpieces.

A circular saw

Due to their ecological and aesthetic properties, wood products, as in the old days, do not lose their popularity today. In order to turn a piece of wood into a product, circular saws of various modifications are used. The circular saw is designed for cross-cutting and longitudinal cutting of both hard wood and softer ones. Also, the power tool copes with sawing various wood-shaving materials, such as chipboard, fiberboard, MDF and sheet plywood brands FS and FSK.

The main criterion by which the best saw is selected. This is its power, since it is impossible to use a low-power tool for sawing hard wood, for example, for oak blanks. Material processing is carried out using a blade with sharp teeth, which, rotating at maximum speed, cuts the workpiece.

You don’t have to be a professional to figure out how to work with a circular saw. The tool is quite simple to operate. It can be customized to perform a specific task. To do this, you need to set the depth, width and angle of the cut. Some models provide for setting parameters, as well as replacing the saw blade. Manually, without the use of locksmith keys. The powerful motor tool can be equipped with a soft start system and can be protected against accidental starting. The saw operates from a 220 V network, although some time ago models that work on rechargeable batteries appeared.

Choosing a circular saw for your home

Like all power tools, circular saws can be roughly divided into two categories: household and professional. A professional tool, as a rule, is more durable, accurate, reliable and has a long service life. But this does not mean at all that only specialists work with it, it will be convenient when doing woodwork for everyone who knows how to handle a power tool.

When choosing a circular saw, it is necessary to pay attention to the diameter of the blade, on which the cutting depth depends, as well as to the rated engine power and the number of revolutions per minute. It is important to consider the balance between motor power and blade diameter, since a large diameter blade designed for deep cuts will only work correctly with a powerful engine. For example, a disc diameter of 210 mm is capable of cutting 45 mm of material, and in order for the engine not to overheat when working with such a circle, its power must be at least 1 kW.

In total, all circular models are divided into three groups according to engine power: low-power. Up to 900 V, medium. 1600 V and with the highest power. Over 1600 V. The most powerful models are distinguished by long service life, accuracy, high performance. But if a saw is needed to solve certain tasks in everyday life from time to time, then, as a rule, a tool is chosen from the first two groups, low or medium power.

When choosing a circular saw, it is necessary to decide for what tasks this power tool will be used. Become familiar with the characteristics of the tool, what power it has and whether the blade is suitable for the required cutting depth for balanced saw operation. The brand under the name of which the tool was released is also important, well-known manufacturers produce circular saws, which are distinguished by a long service life, and contribute to the high-quality performance of work.

Circular saw for wood: features of choice

A circular saw, popularly known as a circular saw, is a multifunctional device that is actively used for sawing, mainly wood or some kind of building materials. It is also often used in summer cottages, performing a large amount of assigned tasks. The name of the tool indicates that the workflow is carried out with a circular disc. In principle, the designation circular also implies the operation of a circular mechanism.

If you need to buy a circular saw for wood, how to choose it and what important points should you pay attention to? Fortunately, the assortment and price range allow you to select the tool that will satisfy the client’s needs in terms of performance and cost requirements.

Circular saw for wood is designed for longitudinal and cross cutting of wood and its derivatives. Indeed, this process itself is quite laborious. It is the use of a circular saw that can reduce time costs, as well as provide a high quality cut.

The tool can be used for cutting plastic, organic glass, multilayer joints. Also, circular saws have been used for cutting metal.

Application area

The main purpose of the tool is work with wood and its derivatives of different classes, plastic and metal products. That is, it is a multifunctional device with which you can perform work of any complexity within the framework of the household and backyard economy.

Saw blade features

Which saw blade for wood to choose and what to be guided by? Saw blades are classified according to the material for which they are designed. The main difference between them from each other is that the number of teeth, the frequency of their location and shape are different. The gaps between the teeth smooth out vibrating movements, noise during operation, as well as expansion that is observed when the metal surface is heated. All the necessary information about the cutting characteristics is usually indicated on the surface of the disc itself.

If you plan to work with materials of different classes, then it is advisable to purchase cutting elements separately for each surface to be treated.

Before choosing a saw blade, pay attention to the number of revolutions. This parameter should correspond to the revolutions that the circular saw performs. If you plan to work with boards that may have nails on their surface, then it is better to purchase a disc with the FWF designation. This will protect the teeth from damage.

A little tip: cutting thick boards, branches can be done with household tools. The sawing process is carried out on both sides.

It is also important to pay attention to the disc diameter. It is indicated in millimeters, indicates the cutting depth:

Households use to work with material with a thickness of 40-50 mm;
Medium can do any work, cutting depth 50 65 mm;
Professional work requires more productivity, the cutting depth is 140 mm;
The size of the disc and the diameter of the seat matter. Small discs are used in household tools and are designed for one-time work.

When choosing a saw, you should pay attention to the diameter of the discs that can be used with a particular model of tool.

Main parameters requiring attention

How to choose a circular saw, what are the main characteristics to consider when buying? You need to rely on the basic requirements for the tool: accuracy of settings and safety of operation, especially at home.

Replacing the saw blade

With active use, the tool may fail. In this case, the saw blade must be replaced. This need arises in situations where you need to replace the disc to work with different material. The replacement procedure largely depends on the mechanism with which the saw is equipped. Some models require special keys. Others have a device for securing the shaft in a certain position, which makes it much easier to change the disc.

Idling

High saw speed and high-quality blade ensure a clean cut. It also matters what material you will need to work with. There are small nuances that are worth paying attention to. The frequency of rotation and the ability to adjust the operating modes of the saw. This parameter is important when cutting plastic products, since they have a tendency to melt at the edges from exposure to high temperatures.

Considering the main characteristics of the tool, you yourself decide which circular saw to choose for summer cottages or home use. Below are additional options that can assist you in choosing such a tool:

Accidental start blocking button. It provides control of the cutting element, which guarantees safety during the working process.
Soft start function. Protects the tool at the time of starting from power surges.
Electrodynamic brake. Momentarily stops the rotation of the disc at the moment the trigger is released. Prevents damage to the workpiece, and is also a preventative measure against injury. This is due to the fact that when the disk is jammed, it can continue to rotate.
Ability to work at an angle. The allowed angle parameters are 30 55 degrees. This is achieved by adjusting the position of the platform in relation to the saw blade.
Sawdust removal mode. A blow-off system can be used at the cutting site. Some models allow the connection of a pump and the use of a container for collecting wood waste.
Base plate characteristics. Cast parts are installed on professional tools. The stamped metal is resistant to impact deformation. The thickness ensures the reliability of the tool. Base plates are required for attaching accessories and accessories. Also, the presence of a base plate is important for the ability to set the tool in a stationary position. This requirement applies to powerful units that can be used without a special table.
Inspect the location of the carbon brush replacement unit. If access to them is open, then the repair of the tool can be done by hand, if necessary. Some circular saws have a brush wear indicator.
The presence of a battery. Some models are equipped with a battery, which allows using the instrument in places where the use of electricity is impossible or has certain difficulties. You can also use cordless circular saws when traveling or where you don’t have access to a constant power source.
The electronic device that the saw can be equipped with greatly facilitates the workflow. Here you can also mark the laser pointer, which shows the cutting location, allowing you to get a smooth cut of good quality. Therefore, in essence, the electronics take over your responsibilities related to speed control, working speed and ensuring the permissible tool load.

Which circular saw is better, electric, cordless or electronically controlled, it’s up to you. After all, this choice depends on the amount of work, the frequency of using the tool and its purpose. It should be noted here that electronics are found only in professional grade instruments and in some medium power models.

How does the circular work?

Fast straight cut. The circular saw is designed primarily for sawing softwood or hardwood materials. The circular saws only in a straight line. With its help, many construction, carpentry and joinery tasks are solved: sawing boards and beams (both longitudinal and transverse), furniture boards, plywood, laminated chipboard, you cannot list everything. With a special disc, the circular is able to cut non-ferrous metals. Some models have a speed adjustment function that allows you to successfully cope with sawing various plastics.

Circular saws rating: top 5

The circular saw is a compact, powerful tool designed for sawing workpieces from a variety of materials. This can be wood, metal, laminate, drywall, plywood or OSB.

Suitable for construction work in summer cottages and apartment renovation. The circular is indispensable for those who like to do housework with their own hands, as well as for professional builders.

Types of circular saws

Circular saws are hand, table, stationary, battery, cable.

Handhelds are ideal for a wide range of household tasks. They are characterized by ease of operation and transportation, compactness and high performance. When working with this type of tool, the material (workpiece) being cut is stationary.

Desktop and stationary are designed for professional construction work and cutting large blocks. They are distinguished by high power, high precision, increased disc diameter and many additional functions. The saw remains stationary, the material being cut moves along the blade.

Table circular saws are suitable for precise cutting of materials at different angles. Sawing capacity 4070 mm.

Stationary models are complemented by a cast or welded bed. The work table is made of aluminum / steel / cast iron sheet, which has a special slot for the disc and ruler guides for convenient and accurate cutting of the material. They have a reduced noise and vibration level, and often have a built-in dust collector. Sawing capacity 50140 mm.

Cable tools operate on mains power and have a limited wire length. They are characterized by high power. Cordless circular saws are battery operated and mobile. They are easy to use and standalone. Often equipped with LED backlighting for easy operation in the dark. The disadvantage is the lower power than that of cable saws.

When working with plunge-cut circular saws, the cutting disc can only be lowered from under the special protective cover after switching on. This improves the accuracy of cutting and positioning of the tool. Sawing capacity 1075 mm. Used for cutting openings in furniture and other purposes.

Any saw can be fitted with a diamond or carbide blade. Diamond blades are designed for cutting stone, tiles and ceramics. Solid carbide discs are suitable for metal work.

How to choose a circular saw blade

When choosing a circular saw blade, pay attention to:

Which circular saw or miter saw to choose?

Are you looking to make a cute table to match your couch but can’t decide between a miter saw and a circular saw?

Don’t worry, read our comparison guide to find out all the differences between the two saws and decide which one is the best for your task.

Some people think that one of them is better than the other, others that there is not much difference between them, and one can replace one saw with another. Nevertheless, each of them has its own characteristics and it is better to use the saw exactly for its intended purpose.

So let’s first take a quick look at the advantages and disadvantages of both types of saws.

Miter saw

What is a miter saw?
Cross-cut is a tool for precise, mainly cross-cutting, cutting of a workpiece. Most miter saws are small and portable. Unlike stationary miter saws, you can pull it out and set it on a temporary base by placing a drop mechanism (sometimes called a drip mechanism) over your workpiece. The blade sizes most commonly used for miter saws range from 8 “to 12” (20-30 cm).

What is a miter saw used for?
You can use it to create cross cuts on a workpiece in one quick motion. But more importantly, you can do it at your chosen angle. It is the best choice when you need to cut trims and moldings.

Pros
The miter saw is useful when you need precise cross-cuts in your workpieces. This saw is also a great option for miter cuts.
This is one of the main competitive advantages of this saw over other types of saws. Most importantly, the miter saw is one of the safest.

Minuses
Despite all the advantages, a miter saw is useless when you are about to cut large workpieces. While it is the best choice for cross-sections, trimming can be ineffective with long cuts (over 15 centimeters).
Miter saws are a luxury rather than a necessity.

A circular saw

Also called circular saw, this saw is equipped with a toothed or abrasive disc that allows you to cut various materials in a rotary motion around an axis.

What is a circular saw used for?
The circular saw is commonly used in a variety of woodworking projects. However, the cutting tasks depend to a large extent on the type of blade that is mounted on the circular saw. This saw can be produced for both left and right hand. During operation, the circular is largely based on that part of the structure in which the engine is located.

Pros
Circular saws are very compact, making them easy to move. Usually, you transfer the circular saw to the workpiece, and conversely, in the case of miter saws, you take the material where the saw is already installed.
These saws are capable of making long rip cuts.
Minuses
This type of saw is much more difficult to use than a miter saw. A circular saw requires more skill and a lot of experience is required to use it.
From a safety standpoint, a miter saw is a better choice than a circular saw.

What is a circular saw and how is it different from a circular saw?

A circular saw is a tool without which it is difficult to imagine modern construction work, whether it is the construction of a residential complex, whether it is the renovation of a country house or an apartment. In terms of cutting accuracy, productivity and maneuverability, it is an order of magnitude higher than other electric saws.

Why do you need a circular saw?

This powerful tool is needed when it comes to the many cubic meters of material listed above and the accuracy of straight cuts. All circular saws are similar in design and differ from each other in power (read performance), cutting thickness, and additional options that determine the applicability, safety, and ease of work with the tool.

We say circular saw, we mean circular

Yes, it’s very simple. Circular saw or circular saw. These are the old names for an electric circular saw, a flat metal blade with teeth on the outer edge for cutting wood, drywall, laminate, plastic and soft metal, and used on machine tools or hand tools. This is how the specialists of the Ataka trading house, the owner of the trade mark of the same name, explained to us, in more detail here

Saw blade design

It is a flat bed with an electric drive and a vertically mounted saw blade, as well as a saw holder (handle) with a power button. There are also auxiliary parts: sawdust collector, guides and hinges, etc. The bed is pressed against the cut plane, and the rotating saw blade, plunging into the material, cuts it.

In terms of power, circular saws are divided into 3 categories.

Immersion in the material (for example, when cutting solid slabs), when the cutting wheel can move vertically, cutting is not done from the edge, but from the middle of the blade.

Adjusting the angular speed of the saw blade. This feature allows you to ensure smooth cuts on different materials.

Saw blade braking. Increases tool safety.

Smooth start, when the jerk is eliminated when the drive is turned on, especially powerful. Safety is also increased and mechanical stresses on the saw blade are reduced.

Illumination and laser marking. The comfort and accuracy of processing increases.

Possibility of mounting on a stand (only for powerful circular saws). This option is very useful in case of large volumes of work.

Circular saw blades differ in tooth height, cutting profile and tooth frequency and are divided into 2 categories: for soft materials and for metal. The first ones have teeth inclined in the direction of rotation (positive sharpening angle), the second ones with a negative sharpening angle.

Rules for the selection of saw blades.

Light circulars cutting depth less than 55 mm. Lightweight compact saws with a power of up to 1000 W (they are also called parquet floors) are not often found.
Middle class saws cutting depth from 55 to 70 mm. This includes most of the models on the market. Their power is 1200-1800 W. These tools are capable of sawing thick boards, have good performance and are not gigantic in size. This is what a mass buyer needs.
Heavy saws with immersion depth from 85 to 100 mm. Powerful circular saws with a disc over 230 mm in diameter are mainly used on construction sites, that is, wherever it is required to saw massive thick workpieces.
Carpentry circulars able to cut to a depth of 130-160 mm, or even more. It is a tool for solving specific tasks such as cutting very thick materials. Such saws are gigantic in size, heavy in weight, have very high power and in some cases require a three-phase network.

Power. This parameter depends on the number of revolutions required for specific work, speed and depth of cut. For simple household purposes, a tool of small (up to 1.2 kW) and medium power (up to 1.8 kW) is suitable, for larger-scale works from 2 kW.
Cutting depth. Most often it is up to 60 mm, up to 150 mm for professional equipment.
Disk speed. The maximum hardness of materials that can be cut with the selected tool depends on it. The higher the speed, the more power the circular saw consumes and the less likely the blade will jam.
Disc diameter. The outer diameter determines the cutting depth (up to 350 mm). The inner diameter of the disc depends on the size of the power shaft of the tool (up to 32 mm); in case of mismatch, an adapter ring can be used.
Body material. It can be high strength plastic or metal.
Work at an angle. The depth of cut is indicated at a right angle, this value is considered to be the main one. Sawing at angles of 45 and 60 degrees is used less often, the ability to adjust them provides convenience when cutting in hard-to-reach places.
Ergonomic handle. Choose the model that fits your hand most comfortably: this way you protect yourself from injury and increase the accuracy of the cut.
Additional functions. These include:

Smooth start for greater cutting accuracy;
Immersion, when the cut needs to start from the middle of the bar (material);
The ability to connect a vacuum cleaner to collect sawdust;
Laser mark that forms the cutting trajectory;
Start blocking to prevent accidental switching on of the device;
Adjustable disc speed and quick braking for increased safety.

Diameter: Must match exactly to the design of the tool, otherwise the work will be unsafe and ineffective. With a smaller blade, fingers can get caught under the protective cover, with a larger blade, it simply will not fit on the saw.
Tooth Frequency: For soft materials, a wide-toothed blade is suitable for a smooth and precise cut. The fewer the teeth, the more hard the material will be cut. Average quantity 4080 pcs.
Teeth inclination: for cutting wood in the direction of rotation, for cutting metal in the opposite direction.
Sharpening angle of teeth: positive (15 to 20 degrees) for wood, negative (0 to 5 degrees) for metal.
Tooth configuration: determined depending on the task. The combined cutter (Combi) is a universal option. The trapezoidal cutter (TCG) is suitable for processing non-ferrous and soft metals, wood and plastics. Replaceable with increased lateral slope (HiATB) for easily splitting materials. Replaceable without tilt (ATB) for processing composite panels, plywood, longitudinal cutting of wood. Flat (FT) for soft and hard wood.
Circular Saw Spindle Speed: This parameter determines the allowable blade diameter for efficient tool performance.
Purpose: manufacturers offer special blades for cutting various materials, as a rule, they have all the necessary characteristics. Only the outer and inner diameters remain to be determined independently. This greatly simplifies the choice.

With an electric motor power up to 1.2 kW (for infrequent cutting of a simple, thin blade (up to 45 mm) with discs with a diameter of 130-160 mm).
With a drive power up to 1.8 kW (cutting depth up to 60 mm with discs up to 200 mm in diameter).
With a power of 2.0 kW and more, with discs up to 350 mm in diameter for cutting even sheet metal and the ability to attach to a workbench, i.E. For more professional use.
