How To Use A Circular Saw Correctly

How to cut a long board in half

The circular saw also handles very long materials. For this, it is necessary to carefully prepare the workplace. It is required either to put the slats under the board, or to saw on the trestles. The technology is almost the same.

The bottom line is to allow the end of the board to fall slightly during the cut, but not lose the position of the circular saw. At the end of the work, the piece to be sawn off will simply fall to the floor, which will be the end result. The main thing is that the board does not fall off before it is completely cut.

Sticky tape for sawing

In order to avoid chips on the material, and the veneer retains its original appearance, you can use adhesive or another molar tape. It will not leave marks on the wooden board, and will also protect the tree from visible mechanical damage.

The tape is attached in the place where the cut will pass. Next, you should carefully cut the board, after which you can remove the molar tape. It can only be dismantled away from the cut and at right angles. The main thing is not to pull the tape up so that the plywood does not delaminate.

Make a cut without stopping

It is advisable not to stop while cutting wooden parts. The circular saw should run smoothly through the material and not interrupt. Otherwise, bumps and cuts will remain on the boards, which will interfere with the further use of the tree.

The movements should be smooth and soft so that the disc does not become dull and runs smoothly on the board. It is also advisable to check the length of the cord in advance. If it doesn’t reach use an extension cord. Otherwise, the tree will also be cut unevenly.

5 tips on how to properly cut wood with a circular saw

The circular saw is a versatile tool for cutting all kinds of parts and elements. To carve wood with this tool, you need to familiarize yourself with some rules that will facilitate the work and help you safely saw the object into small parts. 5 tips on how to properly cut wood with a circular saw will greatly simplify the task of repairing.

How to cut a window in a piece of plywood

Sometimes the boards need to be sawn inside, cutting out the so-called window from the common part. But this must also be done with the observance of special rules. First, you need to mark a point at the cut. It should line up with the corner and middle parts of the circular disc. During the whole process, the marked line of the cut should be slightly to the side.

The main thing is to smoothly lower the circular disc into the plywood so that a return blow does not occur. Further, at full power, you can directly cut. Completion of work can only be carried out when the tool is completely stopped.

How to cut a small piece of board without the goats

You can easily use a circular saw to cut small pieces. To do this, you can not even use the goats, but simply put the board with an edge on the toe of the leg, the shin will serve as a support. Next, it is worth drawing the cutting line, aligning the tool on it and cutting.

The main thing is to maintain a safe distance from the incision to the leg. It must be more than 30 centimeters. At the end, the element to be sawn will simply fall to the floor, where the client should lie in advance under the sawdust.

The circular saw is suitable for cutting elements of any complexity and shape. It is necessary to follow the rules and requirements for safety, so as not to spoil the material and not injure yourself. Therefore, tips will help you avoid mistakes when sawing wooden planks with a circular saw. They must be adhered to, then the work will be done efficiently and without defects.

About the quality and result of work

Everyone loves that the work was done conscientiously. How to work with a hand-held circular saw correctly and achieve a high-quality result?

Pay attention to the longitudinal and lateral balance of the saw. The cutting efficiency is directly dependent on the correct balancing of the machine. Any misalignment causes inconvenience, stress and severe fatigue during work.

The quality of the disc sharpening also greatly affects the process of work. This is especially true for low-power models. You can sharpen a disc in many places, the main thing is to do this before starting work.

The need for sharpening is determined at a number of points:

  • During work, you need to apply more forces than usual (this is not drinking water);
  • The edges of the cut begin to burn;
  • Frequent engine overheating.

If you let this moment take its course, then tool breakage is not far off. This will be eloquently indicated by the smoke coming from the saw and the smell of molten insulation.

Benefits of electric circular saws

Various types of circular saw blades.

There are models of saws that, during operation, control the load on the tool, protecting it from overheating, and are able to control the speed of the mechanism.

Most circular saws are equipped with an overload indicator and brush motor. Replacing discs is very safe due to the built-in quick braking system and blocking the engine of the device.

A range of electronic saws allows to measure the number of revolutions during sawing when the blade is moving. This function allows you to work not only with wood, but also with plastics and some soft metals.

advanced models are equipped with an electronic soft start system. Thanks to her, such tools quickly gain momentum at an even speed.

It is very difficult to get injured in this case, since such models have a protective cover from the saw teeth. It smoothly, without jerking, moves away from the disc during the start of work. Some tools of this kind are equipped with a pendulum cover and an infeed roller.

Many models used for both professional and domestic work are equipped with special outlets for connecting a vacuum cleaner. Despite the reduced maneuverability, such a tool lasts longer, since the number of negative factors is significantly reduced.

How to use a circular saw correctly

Thoughts about purchasing a circular saw arise when a large amount of work is required to cut timber or boards along the material. Of course, you can use a hacksaw or jigsaw to loosen the boards if you wish. The masters will masterfully cope! However, if cutting with straight lines is required, then a circular saw is required for such work. This power tool is used for cutting wood as well as plastic and soft metal.

It would seem that the question of how to use a circular saw is quite simple and the answer to it is clear. However, not all so simple.

A little about the available teeth

Circular saw dimensions.

When choosing a saw for the job, the characteristics of the teeth must be considered. This is necessary because a specific material requires its own type.

Circular saw blades with standard teeth are used for soft woods and plywood.

For hard rock or chipboard, special carbide teeth are suitable. In addition to the special shape and more, they have victorious soldering.

For chopping work, such as ripping boards, a disc with a small (up to 24) number of teeth is suitable. The smaller there are, the larger their size. Accordingly, the blade will cut faster, but the cut will be rough.

For fine cutting, discs with teeth up to 36-48 units are suitable. Working with hardwood material or planks with nails will require 54 trapezoidal discs.

The inclination of the teeth can be positive, such that it cuts wood. A disc with a negative tilt is used for clean cutting of aluminum and plastic.

Types of circular saws

Types of circular saws.

For domestic needs, manual options are quite suitable, capable of transverse, longitudinal and oblique cuts. They are distinguished by their maneuverability, lightness and relatively low cost.

A number of models allow you to cut not only from the end, but also anywhere thanks to the special plunge function. Due to the ability to tilt relative to the slab, such models cut material at different angles.

The base plate of such a tool is made by a stamped method (suitable for domestic purposes) or cast (for a professional tool).

For large volumes of work, you will need a stationary circular saw with a box-type bed. They have been used before. Modern models are made very compact, which allows them to be placed on work surfaces, such as workbenches.

For professionals, more massive tools are needed, which are placed directly on the floor of the room. They are able to influence the cutting depth thanks to the movable work table. The disc remains stationary during operation. Thanks to this, the possibilities of the circular saw are greatly expanded.

If the work is often carried out with variable load, then combined options are suitable. They differ from manual ones in that there are special mounts in their case, which make it possible to work stationary on any horizontal surface. In this case, the saw is fixed with the disk up.

What you need to know about the circular saw?

Circulars are simple. They consist of a base plate and the actual saw. The base plate is constructed from aluminum alloy or stamped steel. There are three types of circular saws: stationary, hand-held and combined.

Before starting work, the maximum cutting depth should be determined. This moment is the main criterion when choosing a hand saw. It makes sense to ask for what purposes a tool is needed: for professional or for household needs?

Also in this case, the size of the tool matters. Generally, a medium-sized circular saw is preferred for its agility and ease of use. For a significant amount of work related to clapboard and thin boards during the construction of a house, a stationary large-sized circular saw is required. Smallest tool suitable for thin rods.

A single-phase circular saw with a power of 220 W can easily cope with summer cottage and household work.

For large volumes, three-phase instruments (380 W) will be required. According to safety rules, they must be grounded.

A circular saw. How to cut it

The main stages of working with the tool:

  • Set the minimum depth of cut by adjusting the blade downward.
  • Fit the guide to the size of the part by measuring the length from the edge of the blade to the edge of the foot. Mark up the material.
  • Make the initial cut 35 mm.
  • Continue cutting without stopping all the way through the blade.
  • Use duct tape at the cut to avoid chipping.

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.

Selection criteria for circular saws

Decide on the amount of work and the required tasks, then decide on the appropriate type of tool. Check the technical specifications of the circular saw before purchasing.

  • Circular saw power. The indicator affects the thickness and density of the material with which the tool works.
  • Circular saw weight. Directly depends on the selected power. Determine which is more important to you: performance or speed. Since a more powerful tool is heavier, which means your hands will get tired faster, more often a break is required.
  • Cutting depth of the circular saw. The small diameter of the saw blade will not allow you to work with a large workpiece, and with a large diameter you will not get a surface cut. Choose discs according to your task.
  • Circular saw speed. Affects the types of materials the tool works with.
  • Work at an angle. Depending on the specific model, the circular saw is capable of cutting at an angle of up to 60 degrees.
  • Sawing metal. A tool that has the ability to work with metal workpieces is considered multifunctional and has a number of advantages over an angle grinder. High productivity and cut quality, no heating of the element and no sparks during operation, the ability to cut metal at an angle. But don’t forget about the high price of a disc for metal.

Types of jobs

The scope of the circular saw depends on its size and type.

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:

  1. 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 blade size in such saws is 160 200 mm.
  2. 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:

  1. Standard. The model is designed for cutting wooden blocks with a density of up to 85 millimeters.
  2. Mini saw. A small circular device weighing up to 2 kilograms and a power of up to 800 watts. Used for cutting thin wood.
  3. 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.
  4. Diamond. This type of equipment is designed for cutting hard materials such as 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.
  5. 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 millimeters;
  • Large from 70 millimeters;
  • Average 55 millimeters;
  • Small from 40 to 46 mm.

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.

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 have a rather heavy weight over 10 kilograms and high power 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 a stationary function. They are successfully used in home workshops.

Types of jobs

The scope of the circular saw depends on its size and type.

Device and principle of operation

The design of the circular saw is pretty simple. The device can be manual, or stationary type, combined models are also found.

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

A circular saw

Cutting boards and bars is carried out by rotating the discs, which have special covers that protect against injury during the working process. The cutting part is triggered by a trigger. Circular equipment allows you to process large volumes of wood.

How to work with a circular saw?

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 models

The circular hand saw is an efficient and safe tool. But still, the use of such equipment requires compliance with some operating rules:

  1. 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.
  2. 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.
  3. 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.
  4. 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.

What can be done with a circular saw

The principle of operation of this unit is based on the rotation of the cutting disc by an electric motor. The saw design is presented in two versions: manual or stationary. An important difference between these two versions is that the force from the engine to the disk in the stationary model is transmitted through the belt, while in the manual model the disk itself is fixed on the shaft. The saw can cut wood both along the fibers and across them, produce a quarter cut. The tool can be used to saw off soft metal, plastic, if you use special discs.

Setting up the circular saw

Before starting work, you should:

  • Put the disc;
  • Make sure that it is securely fastened;
  • Make sure that the protective cover opens freely and returns to its original position when the handle is released;
  • Check the correct installation of the riving knife;
  • Make sure that the saw is working properly by holding it in the ON mode for 10 seconds without load.

It is quite easy to adjust the saw before use. This requires:

  1. Adjust the position of the guide slot on the table and disc using a vernier caliper, aligning the guide slots on the blade. When checking the tooth in the front and back of the blade, the difference should not exceed 0.05 mm
  2. Check the parallel stop with a slot or slot. Here the offset should also not be more than 0.05 mm.
  3. Make sure to align the riving knife with the blade so that it is on the same line as the blade. In case of a mismatch, a more accurate adjustment is achieved by rotating the washers
  1. Tighten the mounting bolts securely to protect the table and the machine from vibration

What is a circular saw for?

It is designed to cut softwood and hardwood boards with a moisture content of no more than 50% and a thickness of no more than 64 mm. It is allowed to cut plywood, aerated concrete, chipboard, asbestos-cement and cement-particle boards.

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.
  • Do not overload the tool by doing work that is not intended for it.
  • If the on / off key is broken, do not use the tool.
  • When changing accessories, making adjustments and other work, the tool must be disconnected from the power supply.
  • Storage of the tool should be done in places that are hard to reach for children and pets.
  • Remember to periodically service your tool.

Circular and circular saws as indispensable helpers in your farm. How to saw and tune the tool?

The forerunners of modern automatic saws were tools made of stone, bones, on which jags were applied from one edge. The beginning of this instrument was laid in the fourth millennium BC. They are used both in household work and in the creation of various works of art.

Then stone and bone were replaced by copper, iron, steel. The first power saws appeared in the XXIV century in Germany. Electric saws only became widespread in the 20th century.
