In appearance, a reciprocating saw resembles a drill. She has an elongated body, a handle, a working trigger at the index finger. There are several types of reciprocating saws. If you are looking for rational ways to use this equipment, this article is for you.

Types of Reciprocating Saw Blades

The right blade is used for different types of work. In its choice, the size of the blade, the type of sharpening, the pitch of the teeth and other parameters are important.

woodwork

To cut wooden structures, it is enough to use a hacksaw marked with the HCS symbol. These saws are made of durable steel, they cut well in soft and hard wood, particle board and fiberboard. The length of the cutting element does not exceed 40 cm.

For sawing soft grades, a dusty chrome vanadium steel blade is used. And for ordinary wood, files are usually suitable, in which there are the same pitch of teeth. Wide pitch tines are recommended for hard, dry wood.

For metal

For metal processing you need to have a blade with HSS marking. It is made of high-speed steel, intended for the work of aluminum, sheet metal and profile. The blade has a length of up to 29.5 cm.

With the help of such a blade, through cuts are made. Some saws use bimetal. For cast iron blades, a special diamond coating is applied to the bimetallic alloy.

For aerated concrete

For cutting tough and porous materials, materials marked HM, CV should be used. The same group includes a blade used to saw specifically for certain types of concrete, as well as steel, tile, fiberglass and fiberglass.

per brick

To work with different types of building materials, HM hacksaw blades are used. They are made of hard and durable alloys with the addition of carbide or chromium. If you need to cut a stone, an ordinary blade is not suitable. For this, a blade with a very hard coating is used.

For plastic

For precise and precise cutting of plastic products, M-shaped files are used. When working with plastic, it is necessary to use a cooling lubricant: this will reduce the heating of the working material and prevent a fire. Heat can be reduced by selecting a low cutting speed.

Reciprocating saw tips

It is a useful and necessary tool for any master, because it simplifies a lot of work. There are several tricks that make working with tools easier and more efficient.

Quick Cut

To speed up sawing, the tool is held at a slight angle to the surface to be cut. This reduces the coefficient of friction and speeds up the process. By pressing the sole firmly against the surface, vibrations can be reduced.

Straighten a bent blade

Sometimes the cutting blade bends during operation. You can level it using a hammer and a flat board. You should equalize by tapping the blade along the entire length, without falling on the cutting teeth.

How to use long blades

To make a cut, you need to bend the end part with pressure.

How to extend blade life

To make the blade last longer, you need to firmly press the soleplate to the surface of the material. To make your job easier, it is recommended that you choose saws with an adjustable shoe height. Of course, you have to work with suitable blades.

A reciprocating saw is a great help when working with many materials. In order for it to serve for a long time and give a good result, you need to choose the right canvas and follow the safety rules.
