Circular saw for wood: features of choice

A circular saw, popularly known as a circular saw, is a multifunctional device that is actively used for sawing, mainly wood or some kind of building materials. It is also often used in summer cottages, performing a large amount of assigned tasks. The name of the tool indicates that the workflow is carried out with a circular disc. In principle, the designation circular also implies the operation of a circular mechanism.

If you need to buy a circular saw for wood, how to choose it and what important points should you pay attention to? Fortunately, the assortment and price range allow you to select the tool that will satisfy the client’s needs in terms of performance and cost requirements.

Circular saw for wood is designed for longitudinal and cross cutting of wood and its derivatives. Indeed, this process itself is quite laborious. It is the use of a circular saw that can reduce time costs, as well as provide a high quality cut.

The tool can be used for cutting plastic, organic glass, multilayer joints. Also, circular saws have been used for cutting metal.

Main parameters requiring attention

How to choose a circular saw, what are the main characteristics to consider when buying? You need to rely on the basic requirements for the tool: accuracy of settings and safety of operation, especially at home.

Safety rules when working with the tool

Considering that a circular saw is a rather dangerous mechanism, it is necessary to ensure safety when working with it. Therefore, first of all, you need to adhere to the following rules:

  • Use eye and hand protection.
  • Use a guide bar to prevent the disc from seizing.
  • Remove the disc only with the tool turned off. It is advisable to disconnect the saw from the electricity.
  • Comfortable rubberized handles. Their shape does not matter. When choosing a saw, hold the tool in your hands, feel it. Note for yourself how comfortable it is for you to hold it. Make simple movements with the saw in hand to see if you will be comfortable working with this tool. These steps will help you choose the right working tool.
  • Pay attention to the location of the electrical wire. It is important that it is located at the back of the saw. Indeed, often, during the operation of the tool, the cord gets under the cutting element.

Additional useful functions

Among the frequently encountered and useful additional functions of the circular saw, the following should be noted.

1. Immersion in the cut material. Very useful when cutting solid slabs. The saw blade with this function can move in a vertical plane, so you can start cutting not from the edge, but right from the middle of the plate.

2. Disc speed control. This function of the circular saw can be realized mechanically or electronically. Different materials require different cutting speeds to ensure smooth, burr-free cuts. Variable speed saws are more versatile.

3. Fast disc braking increases the level of security.

4. Smooth disc start also improves safety by eliminating the dynamic jerk when starting the engine. This is especially important for powerful electric motors. It also reduces the load on the electrical network and device mechanics.

Five. Built-in backlight and laser marker greatly increase the comfort of use, and improve the cutting accuracy.

Powerful saws are equipped with devices for fastening to any frame. Thus, the saw is stationary, and cutting is carried out by feeding the material to be cut to the disc. This is a very useful function if you have to cut large volumes, calculated in cubic meters.

How to choose a circular saw

Selection in general is carried out according to the following rules:

For example, for accurate sawing of chipboard or boards, you will need a simple circle with frequent teeth, of which there should be about 100 pieces on the disc.

For breaking up a slab, which is rich in hard knots, a reinforced disc with a minimum of cutting edges (24 pieces) is better suited, which will cope with unforeseen difficulties, but in this case there will be no smooth cut.

The size of all discs is always designated the same. These are two numbers, the first of which indicates the diameter of the disc itself, and the second the diameter of the central hole on the disc, i.E. Bushing diameter, for example, 160×30. Therefore, to acquire it is enough to know these two numbers.

Food type

The current technology allows the production of battery flooring. They are more mobile, safer and in terms of technical characteristics are not inferior to network counterparts. Charging the battery takes about half an hour.

Battery voltage may vary. The highest figure for Dewalt parquet flooring is 54 V.

Most cordless tools spin faster than mains powered tools. Perhaps the highest revs are found in Bosch and Devault parquet floors. Network models are appreciated mainly for their lower price.

The length of the cord for a professional circular saw should be about 3-4 m. Ideally, the cord is located at the back and has a long and stiff entry sleeve. Otherwise, there is a high chance of accidentally cutting the wire.

Application and benefits

First of all, you need to understand for what purpose the parquet is purchased. Almost all tools on the domestic market are professional. Household parquetry is produced by BlackDecker, they are also among Bosch products. They are distinguished by their compactness, lighter weight, high rotation speed, but they are designed for light use.

The key purpose of the parquet is sawing wood. Of course, other power tools can also cope with this task, but the circular is able to easily and quickly make a flawlessly even cutting line, both longitudinal and transverse, evenly and at an angle. Also, the parquet can cut plastic, chipboard, laminate, plywood, etc.

Some manufacturers, such as Dewalt, produce consumables that can easily cut wood with nails. Others cope with slate, stainless steel and aluminum. The type of material to be processed depends on several parameters: power, speed of work, size of the saw blade, number of teeth.

When choosing a parquet, it is necessary to determine the required cutting depth. It depends on the disc diameter, density and workpiece width. You also need to understand whether the parquet will work with the guide and how often. For regular use, the Dewalt circular with molded sole and track slots is suitable.

Cutting depth

Three classes of circular saws are conventionally distinguished:

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

How to choose a circular hand saw?

When buying a tool, you should focus on a number of specific parameters:

  1. Engine power. The higher it is, the faster and with less effort you can cut. In addition, large-diameter cutting blades can be installed on powerful saws (from 3 kW).
  2. Cutting depth. There are 4 standard sizes that you need to select based on your needs.
  3. The hand-held circular saw for wood can have an adjustable cut tilt.
  4. Stationary chip removal system or the ability to connect a vacuum cleaner. A very convenient option that allows you to work with virtually no dust and debris in the workshop or at home.
  5. The start lock is an important safety feature to prevent the tool from being switched on accidentally.

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 Germany in the XXIV century. Electric saws became widespread only in the 20th century.

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, cut a quarter. 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 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. Align the riving knife with the blade so that it is on the same line as the blade. In case of 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
