For repair work or during construction, a tool is needed that can work with wood quickly and efficiently, ensuring it is evenly cut. Such a tool is a circular saw for wood, to work with it quickly and conveniently. But we can not think that all the saws are the same, it is enough to buy the model you like and 2 interchangeable cheap discs, then start the work. In fact, everything is much more complicated; when choosing a saw, one should pay attention to its power, technical characteristics, conditions of work with the equipment.
Scheme of using the saw.
Special attention should be paid to saw blades, because it depends on them what material can be processed, what quality the cut will turn out. All canvases differ in the material used, the shape and size, the pitch of the teeth, and other important parameters that affect the quality of the cut. Today, manufacturers offer a large selection of wood processing equipment. When buying, you need to pay attention to what materials and types of wood disks are intended for.
When choosing a power tool for working with wood, attention should be paid to the selection of the cutting blade. It depends on him, with what material it will be possible to work. Before choosing the disc diameter, it is necessary to take into account the rotational speed, the maximum and minimum speeds.
For the correct selection of the saw blade, it is necessary to pay attention to the following parameters:
Band saw blade profile.
When the saw blade and the saw blade are selected, you should immediately decide which material will be processed, for what kind of work you need a tool. Today, manufacturers offer a wide range, but all models are designed for specific work, so the choice should be given maximum attention.
For example, the rotational speed can be highly dependent on which raw materials require processing. From the frequency depends on the selection of the diameter of the canvas. The following data should be considered:
The dependence of the disc diameter on the equipment rotation speed:
The larger the diameter of the saw blade, the smaller the rotational speed for the saw. This must be taken into account during the selection of equipment and its components.
The dependence of the cutting speed on the selected material:
The shape of the teeth of the saws without tacking.
When choosing a tool, it is necessary to take into account the fact that the saw teeth have different shapes, sizes, and can be used at different speeds of work. As an example, we can consider the following characteristics:
It must be remembered that all manufacturers on saw blades must indicate the required parameters. You can easily determine what kind of equipment is needed to perform the planned work.But besides speed, thickness, speed and other indicators, it is necessary to remember that circular saws are of different types, not only hand saws. It is necessary to determine the tale for which tool the specific saw blade is made.
When asking how to choose saw blades for wood, you need to pay attention to such parameters as the shape, size of saw teeth. Today, manufacturers offer such disc models for saws intended for wood processing:
Disc shapes for circular saws.
For a manual circular saw, it is recommended to use a saw blade with a beveled tooth, which is great for a variety of construction work. With such a tool, wood can be processed in the transverse or longitudinal direction, soft and hard wood, cutting of panels, beams, which have nails, metal brackets and other fasteners of small thickness, is also possible. Such circular saw blades for wood are considered to be the best, since the field of application is wide, and preparatory work (for example, removal of nails) may not be required. The cost of saw blades is not very high, it is usually about 2 times lower than for specialized ones.
Variable teeth discs are used for hand saws, with which composite panels, wood plates, plywood, solid soft, hard wood can be processed. Cutting is possible in the transverse and longitudinal direction, the tooth itself has a positive front angle of 15 °. Such a disk is perfectly applied not only with a hand tool, but also with circular saws.
To ensure thin kerf, if the wood is used is massive, difficult to work, you can use special discs with variable teeth. They have a positive right angle and a so-called feed stop. The job is easy and fast, you can process materials that even have knots, which often causes many problems even when using expensive disks.
In some cases, when preparing finishing materials from abrasive, exotic wood, for the production of panels special discs are required that are able to cope with such a task qualitatively and quickly. For this, there are special blades with a variable tooth with a slope of 15 °. The cut is provided in the transverse direction, they can be used for format-cutting, conventional circular saws. It is possible to process such material as soft, hard, high-quality and expensive wood, laminated MDF panels with a thickness of 30 mm, chipboard with a thickness of up to 50 mm.
If you plan to work with a manual circular saw with exotic wood species, you can also use a disk with carbide taps and a straight tooth.
In this case, it will be possible to cut the material along the fibers, while the circular saw is excellent not only with exotic species, but also with very hard dry or wet wood, soft and wet.
When choosing a saw for work, special attention should be paid not to the parameters of the equipment itself, but to the characteristics of the saw blades. It depends on him with which wood the saw can handle, what working conditions are possible. For example, there are disks that cope with almost any type of raw material, but they cannot be called universal, since they are not suitable for exotic breeds.
