How To Use A Hand-Held Circular Saw

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.

How To Use A Hand-Held Circular Saw

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 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.

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.

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 3-5 mm.
  • Continue cutting without stopping all the way through the blade.
  • Use duct tape at the cut to avoid chipping.

Here’s a stupid question. All my life I sawed with stationary circulars. And here I bought a hand saw (because it is more convenient to carry it with me), but I don’t know where it’s going to be. For example, you need to cut a 6 meter board lengthwise. how is it more convenient to fake the board?

. Can be screwed with self-tapping screws, only below the plane of the board and not along the course of the disc. Saw off and unscrew. Well, if there are no clamps, and they don’t import into the country.

Why also a stupid question?

Why cut a board? Wide board, for example.

I fastened it with an ordinary narrow wedge at the end of the board, narrow so that it does not stick out above the board

And in the middle there are two turning bars with a beveled edge so that the wire does not cling. The table top was two fifty planks and six rectangular supports hammered together. There is nothing tricky.

When cutting a 6-meter fifty with a width of 15-40 cm. As a rule, there is no need to fasten the board with a hand circular saw. its own weight is enough. Put a couple of bars under the top board so that the next board is not grabbed by the disc. and forward, except. I don’t want to.

From personal experience.

And there is no special need to fix the 3 meter high.

I have an even simpler question (from the category, help a teapot): How to cut a 3-meter board across, into 6 slabs of 50 cm each. Suppose I marked everything with a pencil, how to fix it on the desktop with improvised means to cut and the board did not run away? Especially the last meter?

If there is a desktop and it does not allow you to do this, then this is a dining table. Make a normal editing table a la fest and use it with pleasure. "Holes are made of a convenient diameter for the handle of a shovel or rake, in a square-nesting way every 100mm. (96mm in the original). I restrain with such a clamp."

I look at the bourgeoisie everywhere these holes are so that it is more convenient to brush off the chips?

This is for fixing the processed material.

I’ll be a little bored, you’re sorry if you already know

When size is important, measure and mark each piece just before cutting. The disc eats up a few millimeters. This must be taken into account when setting the saw-blade along the markings. Of course, if you just need six more or less identical fragments, you can neglect.

Sorry again, if this is self-evident for you.

Why is that? The first workpiece is carefully marked and cut, then all the others follow it as a template. And you don’t need to pencil, just touched the template with the disk and go.

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.

Operation Algorithm

Hand and stationary circular saws have a similar working principle. But hardware management has some differences.

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.

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.

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 number of electronic saws allow the sawing to measure the number of revolutions while 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.

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.

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 open the boards if you want. 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.

Circular saw layout.

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.

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. As a rule, a medium-sized circular saw is preferable due to its maneuverability 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.

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 it 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 overheating of the engine.

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.

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;
  • Verify correct operation of the saw by holding it in the ON mode for 10 seconds without load.

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

  • 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
  • Check the parallel stop with a slot or slot. Here the offset should also not be more than 0.05 mm.
  • 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
  • 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.

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.

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.
