What is the difference between a circular saw and a circular saw

What is a circular saw and what is the purpose of this tool

The circular saw is called a specialized type of tool, which is designed for cutting wood flat and sheet materials. Such materials include laminate, plywood, fiberboard, particle board, and many others. In addition to working with wood, the device can also be used to cut soft metals and stone, which requires replacing the cutting element disk or circle.

The tool has found its application in specialized establishments involved in the manufacture of furniture. In addition, carpenters are particularly interested in the tool, because it can be used not only to cut wood straight, but also at different angles. Circular saws are also found in garages at home craftsmen, where the device in question replaces the stationary circular saw.

Circular saw advantages

Why many people prefer these circular tools? They have a lot of positive aspects, for which they are valued by professionals.

  • The circular saw makes cuts in wood very quickly and copes well with large quantities of wood.
  • Makes a smooth and accurate cut along a specified path.
  • Manual circular tools are compact in size and lightweight. They can be carried to a more comfortable place when needed.
  • Since the circular saw works from the mains, it does not emit harmful emissions, has no contraindications for work. The circulator can be operated even in rooms without ventilation.
  • These circular saws make little noise. They are easy to use. Long service life and high productivity.

Basic Types and Characteristics of Electric Circular Saw

The number of teeth matters when choosing a circular saw. This is the parameter that will determine what kind of material can be handled most effectively with the circular saw. Regarding this characteristic, there are models:

  • 50 teeth. This model is also called combined flat. This circular saw is sold in many stores in Ukraine (Kiev and other cities). It is chosen because this model combines 40 beveled teeth (for cross-cutting) and 10 flat teeth (for longitudinal work). Circular saw teeth are arranged in blocks of five. Such models are quite handy, as they perform even cutting of different types of wood.
  • 40 teeth. The universal circular saw of this model perfectly copes not only with longitudinal but also with cross cutting of materials. This circular saw while working with plywood leaves almost no chips. It is easy to buy this device. Circular saw models from different manufacturers will vary in price, but by the features of the work are all about the same.
  • than 60 teeth. These circular saws are designed exclusively for cross-cutting. The teeth are shaped like a regular triangle. Usually this circular saw has from 60 to about 100 teeth.
  • Less than 40 teeth. These circular saw models are only longitudinal. They can have from 10 to 40 teeth with big gaps between them. This allows for better chip and debris removal during operation.

An important indicator is how many teeth in a circular saw cut simultaneously. If the index ranges from five and up to seven, the circular tools will create a clean and even cut. But they also heat up faster. For thick and tough materials circular saws are used with three teeth working simultaneously.

The shape of the teeth of the circular saw, their sharpening and the degree of inclination are important. All this will affect the cut. As you can see, there are different combinations for any given application.

Circular saw blade angle can be positive or negative. The higher the positive slope, the quicker and faster the tool will work. It does not need much effort to use. Circular saws cut more precisely and accurately with a small positive tilt angle. There are special model markings for this characteristic.

  • FTG. This variant of circular saw is used for longitudinal work, where the speed is important and overheating of the disc is harmful.
  • ATB. The bevel angle in this case can vary. This circular saw makes it possible to make quick and qualitative cuts in a short period of time. However, the endurance of the blade is not the highest.
  • Hi-ATB. The circular saw is used for chipboard, laminate and other similar materials. Also suitable for plywood or wood that can split. Tooth angle 30 to 40 degrees.
  • ATB/R. Combined options, when one circular saw has teeth for two types of cutting (along and across).
  • TCG. Here the teeth alternate in size in a circular saw. These are the high and low flat versions. Suitable for cutting fiberboard, for example. Have a high durability.

Table-top and hand-held circular saws are available in terms of design. The latter are more compact and lightweight. They are easy to transport and are often in the arsenal of home craftsmen. And stationary circular saws are used in factories when working with sturdy wood in large volumes.

Important parameter will be the coating of the circular saw. Many manufacturers create different coatings that are designed to keep the circular saw blade from overheating, prevent it from rusting, help with cleaning, etc.д. The most common saw blade coatings are nickel, teflon, aluminum (alloy).

What is the difference between a sliding compound mitre saw and a circular saw?

Trimmer and circular saw. saws are very popular, and in carpentry and furniture workshops you just can’t do without them. But often inexperienced users don’t even know that they are in fact different from each other. these are different tools. The fact is that outwardly the saws are similar, and they perform the same function. Sawing the workpiece with the disc. Both saws have a flat blade with teeth on the outer edge. It is installed on the axis of the electric drive. The work consists in the fact that the disc rotates and makes a cut in wood, plastic, laminate, aluminum.

That’s all they have in common. And now let’s talk about the differences.

  • Circular saw. Manual or stationary device. Working with a manual circular saw, the user spends a saw along the line of cutting material. In a stationary circular saw, the workpiece is pushed using a parallel stop, achieving the desired width. This is how one cuts slats, cuts off unnecessary material to size. The circular saw cuts the board along and across the wood fibers. The saw head and blade are tiltable in both directions of rotation so that a diagonal cut can also be made. But remember, the maximum cutting depth is considerably reduced (by 1,2-1,5 times). Circular saw has the ability to adjust the depth of sawing, which allows you to make a selection of grooves in the workpieces.
  • The mitre saw has another name. pendulum. Its design difference is that the saw blade swings with the motor, resembling the measured oscillation of a pendulum. Installation is supposed to be stationary. on a table, workbench or even on the floor. The saw is firmly secured using clamps or bolts. Trimmer motor works in three axes together with a cutting disk. Particular precision is given to the pivoting angle. The degree scale is extremely precise and in very expensive models has no errors and indicates the smallest degree of rotation.

Trimming circular saw of wood craftsmen is also called “trimming”, which means that it saws at a set angle, i.e. precisely at a trimming angle. Thanks to trimming, carpenters and furniture makers get a neat connection of parts at an angle. without gaps and curvature. Sawing mitre cuts. this is the end facing.

So what do we get when we compare these two saws, the crosscut saw and the circular saw?

  • Same cutting principle. both with the disk mounted on the axis of the electric drive. Cutting head with blade can be tilted in both saws. cutting along and across the grain of the wood. also.
  • The way of cutting is different. Trimmer and the workpiece is fixed on the surface, and in the circular saw we either guide by hand along the cutting line (manual), or push the workpiece (stationary);
  • Cutting possible: with a circular saw along and across fibers, with a trimmer.only crosswise;
  • Cutting width. the circular saw has no limitations (we just drive the blade as long as necessary) and the possible width of facing depends on the size of the saw blade.

It turns out that a circular saw (for cutting long parts) and a mitre saw are both needed in the workshop. for precision bevel sawing. Sometimes craftsmen buy universal equipment: facing and circular saw for dacha in one machine. This combination saw has an upper table (on top, above the motor and disc). It is good in that the upper part of the disk saws straight long cuts, and the lower part. Ends in the exact degree of angular trimming of the edge of the workpieces.

What characteristics of circular saws to consider when buying

The first parameter that is important when buying a circular saw. is its type.

  • Handheld circular saws are small in size and weight. They are good for cutting fixed or stationary surfaces, and can be used in the home.
  • Stationary circular saws. are powerful and productive machines that are used in production. They are suitable for quickly cutting large quantities of material. Combination models can be used both as a hand-held tool and as a machine tool. Their purpose. production.

Other parameters also affect the capabilities of the circular saw.

  • Saw blade speed: the higher the speed, the more accurate the cut and the less likely the saw will wedge while working. When working with hard types of wood high speed is mandatory.
  • The power of the saw determines the cutting speed. The more powerful the tool, the faster it will work. Among circular saw models power gradation up to 800 W is encountered most often (small power saws, for home or occasional use), from 800 to 1200 W (medium power, quite suitable for production purposes), over 1200 W (high power saws, related to professional equipment).
  • Diameter of disc size, it is calculated both on external and internal size, in professional circular saws it can be up to 230 mm and more.
  • Tilt adjustment: when choosing a circular saw it is necessary to remember that not all models have the ability to cut at an angle. There are those models, which allow sawing the material strictly at an angle of 45 degrees, there are also those that allow sawing at an angle of 60 degrees. Most saws also have adjustable cutting angle on one side only. If you want bi-directional adjustment, you need to check this when buying: such models exist, but not many.

In addition to the main characteristics responsible for the quality and reliability of the saw, you should pay attention to additional features for ease of use:

  • Disk speed regulation. allows you to choose the best mode for working with different kinds of materials.
  • Mains or battery powered.
  • Soft start. a feature to avoid overheating and failure of the saw motor.
  • Built-in laser level, with which you can check the accuracy of the direction of the saw.
  • Locking against accidental start. A useful function, especially for household saws.

And, of course, you should pay attention not only to the combination of basic and additional parameters, but also to the cost of the equipment. A quality tool does not always have to be very expensive, but you should not choose a saw in any price range if you plan to actively use it.

Applications and benefits

First of all, you should understand for what purposes you buy a parquet flooring. Almost all tools on the domestic market are professional. Household floor saws are produced by BlackDecker, and they are also available from Bosch. They are distinguished by their compactness, lower weight, high rotational speed, but are designed for non-intensive use.

The key purpose of a parquet is to cut wood. Of course, other power tools can cope with this task, but the circular saw can easily and quickly make a perfectly smooth line of the cut, both longitudinally and transversely, evenly and at an angle. Also the parquet can cut plastic, chipboard, laminate, plywood, etc.п.

Some manufacturers, such as DeWALT, produce consumables that will easily saw wood with nails. Others are good for slate, stainless steel, and aluminum. The type of material to be cut depends on several parameters: power, operating speed, saw blade size, number of teeth.

When choosing a parquet, you must determine the required cutting depth. It depends on the disc diameter, density and width of the workpiece. You also need to understand whether the parquet will work with the guide and how often. For regular use, the DeWALT circular saw with a molded sole and grooves for the guide is suitable.

Cutting depth

There are three classes of circular saws:

  • Light: 40-50 mm, suitable for short cutting of sheet materials, soft wood. Designed for home craftsmen;
  • Medium: 50-65 mm, universal models;
  • Heavy: up to 140 mm.

Professional solid tools

This classification is arbitrary, i.e.к. It varies from manufacturer to manufacturer. There is no such thing as a Makita with a shallow depth of cut.


The blade speed affects the permissible density of the material to be sawn and the cleanliness of the cut. For household needs 1500-4500 rpm is enough. Higher speeds are required for consistent work.

Average rotational speeds of the leading manufacturers, such as Makita, Metabo, DeWALT. 5000 rpm. Some of the fastest circular saws are available from Bosch with a maximum speed of 6250 rpm.

If possible, it is better to choose a circular saw with adjustable speed, as high speed is not always needed. For example if PVC is cut too fast it can start to melt.


The harder the material and the deeper the cut, the more powerful the circular saw has to be. The most simple circular saws have a power of 600 W, the professional saws have a power of up to 2,5 kW. The higher the value, the heavier the tool.

Some market leaders (DeWALT, Metabo, Bosch) achieve high performance with little power by increasing the speed of the disc and reducing its thickness. This makes the parquet saw lighter.

DeWALT pays special attention to the level of tooling that is used for the job. For simple gadgets, you need a more powerful handheld tool.

Power Type

Current technology makes it possible to produce cordless floor saws. They are more mobile, safer and in technical specifications are not inferior to their mains counterparts. It takes about half an hour to charge the battery.

The battery voltage can vary. DeWALT saws have the highest value at 54 V.

Most cordless tools spin faster than cordless tools. Bosch and DeWALT power tools perhaps have the highest RPM. Mains models are valued mainly for their lower price.

The cord length of the circular saw for professional use should be about 3-4 m. The cable is ideally positioned at the back and has a long and rigid inlet sleeve. Otherwise, there is a great chance of accidentally cutting the wire.

Circular saw blade

The number of teeth of the circular saw determines the cleanliness of the cut and how hard the material can be sawn: the more of them, the cleaner the cut and the more difficult the task will be to cope with the saw.

A large-sized consumable requires a powerful motor and high torque.

Thickness is another factor. Thin blade coupled with high RPM makes good cuts at low power. The thickness also affects the weight and durability of your parquetry. Thinnest consumables in Metabo, DeWALT and Makita circular saws.

Serious manufacturers try to reduce vibration. DeWALT makes special anti-vibration slots to this end, allowing the thickness of the disc to be reduced to 1mm.1.7 mm.


The base plate rarely gets the attention it deserves. And for nothing. Because the functionality of your circular saw depends on it. Cast aluminum alloy platforms are considered the best. They are lighter and retain their shape very well.

Additional features

Smooth start: when any tool is turned on, the voltage rises sharply above the rated voltage. Such a spike can cause a network reset. The soft start function allows you to gain speed smoothly, reducing the load on the gearbox. The result is a longer service life of the saw. The power tool also has a gyroscope effect at high speeds. The occurring force is not always directed at the right point. Smooth startup ensures better control of the tool at higher speeds.

Constant electronics: if the saw hits a patch of tougher material, a nail, etc. п., or the workpiece is fed in faster, cutting quality and speed remain the same, and jamming of the consumable is almost entirely avoided. Constant electronics are available on Metabo, Bosch, DeWALT heavy-duty parquet trucks.

Unintentional start protection: the button to be pressed simultaneously with “Start” prevents unintentional start-up. The Bosch Parquet is equipped with a two-way safety switch.

Sliding clutch: if the blade gets stuck in the workpiece, the clutch releases the motor shaft and prevents the motor from overheating.

Overvoltage protection: if there is a sudden voltage drop or if the windings overheat, the circular saw’s power supply is cut off, preventing a breakdown.

Angle and depth of cut adjustment: These parameters in modern circulators are quickly, accurately and reliably adjusted with special mechanisms.

Changing accessories: consumables are changed quickly with a quick-action release lever or a key.

Ideal cutting: parallel stops and guide bars ensure this. The latter are attached by means of an adapter, as on Metabo, DeWALT, etc., or directly. Some models have a laser marker. The Bosch parquet is equipped with Cut Control and Guide Rail to help you cut in a straight line.

Dust extraction: Sawdust is either collected in a bin as in Bosch or extracted with a vacuum cleaner as with Metabo, DeWALT parquet tools.

Good view of the work area: Preferably the platform design provides a clear view of the cutting line.

Ergonomics: weight, size, shape and position of the handles are important for comfortable operation. They should be rubberized, non-slip.

Safety guard: all circular saws have a spring-loaded guard. It only opens at the beginning of the cut and closes at the end.

On today’s market there is a wide range of manual circular saws. The first place belongs to circular saws of large manufacturers of power tools: Metabo, Bosch, Makita, DeWALT.

How to cut a board evenly with a circular saw

Unlike a stationary pendulum saw, a circular saw is more difficult to make a straight cut. It will not be a problem if the board or bar is narrow, but for sawing wide workpieces or when making a longitudinal cut, you need to know how to make the cut as accurately as possible. To do this you need to stick to the following sequence of operations:

  • There must not be anything under the piece of material that you will be sawing. The circular saw blade must not cut into anything else. For example, never lay a board on a concrete floor. use a sawhorse or cut-off machine table instead.
  • Mark out the fishing line on which the saw blade should pass. Use a tape measure, ruler or square to check.
  • Adjust cutting depth. Blade should barely protrude beyond the workpiece. For example if the workpiece is 40 mm thick the cutting depth should be 45-50 mm.
  • Check the blade guard. It should lift gently when the saw is lowered onto the workpiece, and immediately close the working part when it is lifted.
  • As you begin to cut, look at the front right-hand edge of the blade and align it with the mark on the material.
  • Look to the right hand guide kerf of the circular saw when cutting at right angles, and to the left hand guide kerf when cutting at 45 degrees.
  • Start cutting the material. Keep your eye on the guide at all times to make a straight cut.
  • Hold the base of the saw flat on the material at all times.
  • Push the saw hard enough for it to cut, but not too hard so as not to overload the engine. It is a good idea to cut the hardest types of wood with as little force as possible.
  • After you finish cutting, make sure that the blade guard is in the closed position.

Circular saw or coping saw which one to choose?

You want to make a nice table to go with your daybed but you can’t decide between the mitre saw and the circular saw?

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

Some people think one is better than the other, others think there is not much difference between them and one can replace one saw with the other. But each has its own special features and it is better to use the saw for its intended purpose.

Let us first take a brief look at the advantages and disadvantages of both types of saws.

What is a circular saw: types and applications

Among the cutting power tools there are two or three that will never be superfluous in the household. Such lucky people include the circular saw, or, as it is abbreviated by craftsmen. circular saw. Circular saw. it is an electric circular saw, it saws with a disk with teeth. Originally, this type of circular saw was conceived only for cutting wooden sheet materials. These include plywood, chipboard, laminate. But if you replace the blade with the appropriate saw blade, the saw can easily cut other materials such as non-ferrous metals, plexiglass, plastic, stone, concrete, tile.

About what you need a circular saw for, what kinds of circular saws exist, and where they are used, you will learn from this article. I will talk about the features of the structure and work of the circular saw, the different variants of its design, as well as what parameters you need to pay attention to, choosing it for home or professional tasks.

Yes, it’s very simple. “Circular saw” or “circular saw”. is an obsolete name for an electric circular saw, a flat metal disk with teeth on the outer edge designed for cutting wood, drywall, laminate, plastic and soft metal, and used on machine tools or hand tools. That’s what experts from the Ataka trading house, the owner of the brand of the same name, explained to us, more here.

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