How To Use A Circular Saw
Nuances of additional functions
Modern models of circular saws are safe equipment with high technical parameters. Many devices are equipped with additional features that make your workflow much easier:
- Slip clutch. Such a device avoids injury if the disc is jammed. The clutch can significantly reduce the shock when the rotating mechanism stops.
- Smooth start. This feature allows the disc to pick up speed without jerking. Soft start protects the mechanism from jolts, which has a positive effect on the operating life of the engine.
- Overload protection. When the engine reaches critical indicators, the mechanism is automatically turned off.
- Support for the required disk rotation speed. Power is automatically added under load when cutting dense materials. This function protects against a decrease in the disc speed.
- Accelerated braking. The disc stops abruptly when the shutdown button is pressed.
- Lock start buttons. This function prevents the instrument from turning on if the switch is accidentally pressed. It is usually installed by simultaneously pressing two keys.
All models of circular saws have a function for setting the cutting depth. When buying equipment, it is recommended to pay attention to the convenience and accuracy of fixing such an adjustment.
Hand models
The circular hand saw is an efficient and safe tool. But still, the use of such equipment requires compliance with some operating rules:
- Electrical connection. When using the saw in areas remote from the mains, an extension cord is often used. It must fully match the power of the circular instrument. Before connecting it, check the integrity of the cable insulation. When connecting the saw to the mains, make sure that the switch on the device is off.
- Fastening material. Wood to be cut should be well fixed on a flat surface. For this, the material is placed on a workbench and fixed until it is completely stable.
- Setting the cutting depth. The required indicator is determined using a special scale on the instrument. When cutting a bar, the disc must not protrude beyond the material, otherwise the workbench may deteriorate. Therefore, it is recommended to fix the cutting depth slightly less than the required value.
- After setting all the necessary parameters, the cutting mechanism should be set in motion. Cutting should only be started when the blade is rotating. The movement of the saw along the material must be smooth and even.
At the end of the working process, the hand-held circular tool must be disconnected from the mains.
Circular machine
Stationary circular saws are equipment for daily use. Such professional machines are capable of processing a large amount of wood per day. They are quite heavy. Over 10 kilograms and high power up to 2500 watts.
Circular machines are used mainly in production for industrial purposes. The cost of such a device is quite high. Some small models of circular equipment also have a stationary function. They are successfully used in home workshops.
Stationary models
The use of circular machines has its own operational features. To cut wood you need:
- Set the switch on the equipment to the off position. Only then can the cable be connected to the electrical network.
- Raising the handle, adjust and fix the cutting height of the disc according to the size of the material prepared for cutting.
- Check the position of the guide bar and saw blade. Their location must be parallel to each other.
- Start the circular saw and make a longitudinal cut of the wood material. Sawing one board should be done in a single approach.
Using a stationary circular saw
After processing all the material, turn off the switch on the equipment, which stops the rotation of the blade, and disconnect the tool from the mains.
Classification of types and sizes
Circular saws are divided into two classes. Household and professional. The equipment differs in power, size and saw blade diameter:
- Household models are small equipment weighing 4 to 5 kilograms, which is usually used for cutting wood at home. Equipment power. No more than 1800 watts. The size of the blade in such saws is 160. 200 millimeters.
- Professional circular saws are designed for processing large amounts of wood. They are able to cut beams up to 85 millimeters thick. The weight of such equipment exceeds 8 kilograms, and the disc diameter is 250 millimeters. Professional saws have a higher power. Over 1800 watts.
Household circular saw model
Several types of circular saws are produced:
- Standard. The model is designed for cutting wooden blocks with a density of up to 85 millimeters.
- Mini saw. A small circular device weighing up to 2 kilograms and a power of up to 800 watts. Used for cutting thin wood.
- Submersible. Equipment is used to cut holes inside the tree. The design of such a saw consists of a mechanism that contributes to the vertical immersion of the blade.
- Diamond. This type of equipment is designed for cutting hard materials. Stone, ceramics or tiles. The working mechanism of the device consists of a diamond disc, which will allow cutting to a depth of 55 millimeters.
- Rechargeable. Such a circular tool has low power and rather compact dimensions. The device is powered by a rechargeable battery and is often used in the construction of wooden houses.
Circular saws are divided into four types, depending on the immersion depth of the blade:
- Professional. From 65 to 140 mm;
- Large. From 70 millimeters;
- Medium. 55 millimeters;
- Small. From 40 to 46 millimeters.
The number of teeth on the disc is of no small importance for the quality of the cut. The smaller there are, the lower the performance of the circular equipment. For large-scale wood processing, special carbide-tipped cutting devices are used.
Types of jobs
The scope of the circular saw depends on its size and type.
How to work with a circular saw?
A circular saw is a special equipment designed for even cutting of boards or wooden beams. The use of the device requires some knowledge and skills. To understand how to use a circular saw, you should familiarize yourself with its principle of operation and operational capabilities.
Hand circular saw
These electric saws are designed for precise, straight cutting of wood materials of small thickness. The handheld circular device is small in size and is most commonly used for home use.
Small-sized equipment for sawing wood is necessary for the interior design of houses. Often, hand-held circular saws are used during renovations to cut laminate or wall decoration material.

Features at work
A hand-held circular saw cannot be classified as a carpentry tool, highly equipped with electronics. For example, only some models have electronic speed control, as this function is not particularly important for woodworking.
modern professional tools have a system that maintains a constant blade speed during operation. Its task, regardless of the load on the motor, is to maintain speed.
Models with an overload protection system monitor the temperature of the motor windings and, if necessary, shut down the machine. Expensive professional equipment is equipped with this function.
Almost any saw can be equipped with a guide rail, with which you can achieve high accuracy in work. They are supplied by tool manufacturers as optional equipment.
Some models can be converted from a hand saw into a stationary installation. To do this, it is enough to screw the protective cover of the disc to the workbench table or long board with special clamps.
How to use a circular saw
How to work with the tool correctly:
- When working, do not use clamps, vices, or other methods of rigidly fixing the workpiece. It is unacceptable to hold it with your hands or body.
