How to use a circular saw

Design and principle of operation

The design of a circular saw is quite simple. The device can be manual or stationary, and combined models are also available.

Regardless of the type, the equipment consists of a saw and a base plate. The last element is made of durable steel sheets or aluminum alloys. The main purpose of a circular saw is accurate and high-quality longitudinal cutting of wood.

A circular saw

Cutting boards and bars is carried out by rotating disks, which have special casings that serve as protection against injury during the working process. The cutting part is driven by a trigger mechanism. Circular equipment allows you to process large volumes of wood.

Recommendations for working with a circular saw

Reading the instructions for the tool is not interesting, it is difficult. The manufacturers themselves are often to blame for this - they write in complex language, small font, and write things that are too obvious. As a result, buyers often rely on intuition rather than rules. Due to ignorance of basic rules, equipment fails prematurely, or even worse, the user is injured.

Classification of types and sizes

Circular saws are divided into two classes - household and professional. The equipment differs in power, size and diameter of the saw blade:

Household models are small equipment weighing from 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 quantities of wood. They are capable of sawing beams up to 85 millimeters thick. The weight of such equipment exceeds 8 kilograms, and the diameter of the disk is 250 millimeters. Professional saws have higher power - over 1800 watts.

Household model of a circular saw
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 wood. The design of such a saw consists of a mechanism that promotes vertical immersion of the disc.
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 disk, which allows cutting to a depth of 55 millimeters.
Rechargeable. Such a circular tool has low power and fairly compact dimensions. The device runs on a battery and is often used in the construction of wooden houses.

Circular saws are divided into four types depending on the depth of the blade:

professional - from 65 to 140 millimeters;
large - from 70 millimeters;
medium - 55 millimeters;
small - from 40 to 46 millimeters.

The number of teeth on the disk is of no small importance for the quality of the cut. The fewer there are, the lower the productivity of circular equipment. For large-scale processing of wood, special cutting devices with carbide tips are used.

Types of jobs

The area of application of a circular saw depends on its size and type.

Hand circular saw

These electric saws are designed for precise straight cutting of thin wood materials. The manual circular device is small in size and is most often used for work at home.

Small-sized equipment for cutting wood is necessary for interior decoration of houses. Hand-held circular saws are often used during renovations to cut laminate flooring or wall finishing material.

Circular machine

Stationary circular saws are equipment for daily use. Such professional machines are capable of processing a large amount of wood in a day. They have quite a large weight - more than 10 kilograms and high power of up to 2500 watts.

Circular machine

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 the function of stationary use. They are successfully used in home workshops.

What can you do with electric circular saws?

Electric circular saws allow you to process wood and wood-based products in different ways, which depend on the type of tool chosen.

Types of work with a hand-held circular saw

The following types of work can be performed with a hand-held circular saw:

trim multiple workpieces laid in one plane;

trim wide boards using a rip fence that cannot be cut on a pendulum saw;

trim boards when laying floors;

trim the workpiece at an angle, without a guide and with its use;

perform longitudinal sawing of the workpiece at an angle;

align the unedged board along a pre-drawn line;

choose a quarter in a board or timber;

cut sheet materials using a guide rail;

By changing the equipment, you can use a circular saw to cut metal profiled sheets;

cut plexiglass and various types of plastic;

Place the hand saw in the table and use it as a stationary circular saw.

Working on a circular saw

Working with a circular saw (stationary) is slightly different from working with a hand-held unit. Using a circular saw you can do the following:

cut and trim wide workpieces, both with a straight cut and at an angle;

perform longitudinal and transverse sawing of wooden panels;

cutting wood-based sheet materials;

open the board at an angle;

sawing an unedged board.

Types of work with a miter saw

You can do the following with a miter saw:

trim wood blanks at any angle relative to the edge;

trim the workpiece at an angle to its face;

a miter saw with a broach allows you to cut wider workpieces;

Operation algorithm

Hand-held and stationary circular saws have a similar operating principle. But equipment management has some differences.

Manual models

A circular hand saw is an effective and safe tool. But still, the use of such equipment requires compliance with certain operating rules:

Electrical connection. When using a saw in areas remote from the power supply, an extension cord is often used. It must fully match the power of the circular tool. Before connecting it, you should check the integrity of the cable insulation. When connecting the saw to the network, you should check that the switch on the device is turned off.
Fastening the material. Wood intended for cutting should be well fixed on a flat surface. To do this, the material is placed on a workbench and secured until it is completely stable.
Setting the cutting depth. The required indicator is determined using a special scale on the instrument. When cutting a block, the disc should not protrude beyond the boundaries of the material, otherwise the workbench may be damaged. 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. Start cutting only with the disc rotating. The movement of the saw along the material should be smooth and even.

At the end of the work process, the hand-held circular tool must be disconnected from the network.

Stationary models

The use of circular machines has its own operational characteristics. To cut wood you need:

Set the switch on the equipment to the “off” position. Only after this can you connect the cable to the electrical network.
Raise the handle to adjust and fix the cutting height of the disk according to the dimensions of the material prepared for cutting.
Check the position of the guide bar and saw blade. Their arrangement must be parallel to each other.
Start the circular saw and make a longitudinal cut of the wood material. Cutting 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 that stops the rotation of the blade and disconnect the tool from the electrical outlet.

How to use a circular saw?

The quality of work performed with a circular saw depends, contrary to popular belief, not only on the tool itself, but largely on the type, quality of workmanship and the degree of wear of the disc.

Therefore, before starting work, you need to make sure of two things - the serviceability of all mechanisms and the compliance of the equipment used with the desired result.

Fixed components of the technological process should be securely fixed. The next stage is the correct choice of mode and installation of the appropriate user settings. In addition to the rotation speed, it is important to adjust the depth of cut, especially when using hand and combination tools, which can damage the bearing surfaces under the lumber. Now you can proceed directly to the work.

Important! It is better to saw the workpiece along the guides of the bed or sole, or, as a last resort, according to preliminary markings or a pointer beam, if provided for by the design.

To make the cut smooth and neat, the disc is immersed in the material gradually and fed forward slowly, otherwise the teeth will “gnaw” rather than cut. While performing work, you should quickly analyze all emerging difficulties and inaccuracies - this will help to quickly eliminate them, for example, by making changes to equipment settings.

Safety precautions when working with a circular saw

Working with circular saws poses three types of danger:

electric shock, injury from moving equipment, and damage from sawing by-products, which can include sawdust, chips, and even broken blade teeth.

To prevent all undesirable consequences, you should adhere to the following simple rules:

carry out preliminary monitoring of the technical condition of equipment;
turn on the power of the device immediately before performing work and turn it off immediately after completion;
be sure to install protective covers and connect a system for removing sawdust and shavings;
wear protective clothing and personal protective equipment; concentrate on work as much as possible, abandon it if you feel unwell;
Carry out regular cleaning of tools and cleaning of the workplace.

Following these simple recommendations will protect you from mistakes and make working with a circular saw easy and safe.

Nuances of additional functions

Modern models of circular saws are safe equipment with high technical parameters. Many devices are equipped with additional functions that make the work process much easier:

Slip clutch. This device allows you to avoid injury when the disk jams. Using a clutch, you can significantly reduce the shock when stopping the rotating mechanism.
Smooth start. This function allows the disc to gain speed without jerking. A smooth start protects the mechanism from shocks, which has a positive effect on the service life of the engine.
Overload protection. When the engine reaches critical indicators, the mechanism is automatically switched off.
Supports the required disk rotation speed. When under load while cutting dense materials, power is automatically added. This function protects against a decrease in the disk speed.
Accelerated braking. When you press the power off button on the device, the drive suddenly stops.
Locking the start buttons. This feature prevents the tool from turning on if the switch is accidentally pressed. It is usually installed by pressing two keys simultaneously.

All models of circular saws have a function for setting the depth of cut. When purchasing equipment, it is recommended to pay attention to the convenience and accuracy of fixing such adjustments.

Safety precautions

Using a circular saw requires caution. To prevent accidents from occurring during the operation of electrical equipment for cutting wood, basic safety rules should be followed:

Before connecting the device to the network, you must make sure that the equipment is turned off;
While working, use protective equipment - gloves, glasses, clothing;
do not allow water to come into contact with the instrument;
do not use the circular device in places with high levels of humidity;
equipment can be moved or lowered to the floor after shutdown only when the disk is completely stopped;
prevent engine overheating;
exclude access to the instrument for children;
cutting boards should not contain foreign objects - bolts or nails;
Before work, check the reliability of fixation of the material.

Proper use of a circular saw will allow you to accurately cut any number of boards with high quality. And compliance with all operational requirements will completely secure the work process.
