Any owner has a minimal set of tools. It is individual for everyone, but everyone has a hacksaw for wood and metal. Its main parts are a handle, a frame, a canvas.

Elements of a hacksaw: what are the main parts

The instrument has become popular also because of its structure. Outwardly, it resembles the letter C, to the ends of which a cutting blade is fixed. This tool contains the following elements:

1. Pen. Modern hand saws have handles that are made using two-component materials. This allows for a longer tool life. The shape of the handle is made in such a way that it is very convenient to use it. Usually it is located either at the top or on the side. In the first case, the tool is used to work in places where it is difficult to get close.
2. Frame. It takes on the main load. It is she who extinguishes all vibrations that arise during work. Modern hacksaw frames are made from a wide variety of materials. Very often, an element is installed on the tool that regulates the tilt of the blade, which allows you to work in places with difficult access. Frames are made in two versions. They can be solid or have the ability to move apart. It is possible to put a canvas of any length on a sliding frame.

3. Canvas. To cut metal, it is made from very hard alloys. It is very thin and fragile. There are many small teeth along the entire length. The work requires special care. You need to buy a canvas that is hardened. If it is not there, then it will fail very quickly. The element with sparse teeth is more efficient. A high-quality cut can be provided only by the one in which the teeth are often located. Recently, bimetallic blades began to appear on the market.

Scope of application of the hacksaw

Tools are made not only by hand, but also electric. Their main task is to cut metal. Naturally, you can make grooves with them, as well as much more. The canvas is made of various materials, therefore, its properties may be different. A locksaw's hacksaw is available not only for sawing metal parts. By changing the type of blade, you can cut objects made of plastic, ceramic or plexiglass. Among the entire range of hacksaws, there are three main types:

1. For household use. Such models are the most common. They are ideal if you need to do something that is not very difficult. They are very easy to use. To fix it, you need to insert it into the grooves and tighten the special screws. The main thing is to remember that the canvas should be well stretched so as not to damage it during operation. Such hacksaws are much cheaper than the others.
2. Hand tools are also of a professional type. They are used when you have to work for a long time, and the cut must be clean and even. A feature of such tools is a convenient handle, as well as a mechanism for quickly changing the saw element. If you need to cut something very often, then it is better to use just such models.
3. Hacksaw handle. The appearance of this tool resembles a staple. They do not need to have great physical strength to work. It is used exclusively where it is simply impossible to crawl with the usual variety. Due to its design, it is permissible to install broken blades in a locksaw.

In the assortment of shops you can find hacksaws, which depend on electricity to work. Their productivity, of course, is much higher, but in terms of mobility and autonomy, they are much inferior to mechanical types.

Features of using a hacksaw

To work the tool comfortably, you need to stand in front of the vice with a half-side. The left leg should be in front. It is she who is the supporting one. The handle rests on the palm of the right hand, with the thumb it is held on top, and the rest is wrapped around the bottom. Place your left hand on the front end of the hacksaw.

When working with a saw, it is usually held horizontally. Movements are smooth, you should not pull. The scope of the tool is needed such that the entire length of the blade takes part in the process. As a rule, two-thirds of the length is involved in the working rhythm.

A typical hacksaw speed is up to sixty strokes per minute. Moving is meant moving forward and backward. At the same time, when working with hard metals, the speed decreases, and soft ones are cut faster.

When the hacksaw goes forward, you should press on it, it comes back easily. Its strength must match the hardness of the metal under the saw blade. The harder it is, the more pressure is needed. Under normal conditions, 0.1 millimeter of the thickness of the web has a pressure of one kilogram. At the end of the process, when the part is almost cut, the pressure should be loosened.

Hand tools, as a rule, do not need cooling after work. To reduce friction, grease is applied to the cut.

If the blade is not tight enough, then the tool is often pulled to the side. This can negatively affect not only the evenness of the saw cut, but also the integrity of the cutting element itself. If this happens, it is best to back off and start a new cut. If you try to fix a cut that has gone to the side, it will lead to damage.

Incorrect hardening of the hacksaw blade contributes to tooth breakage. This can happen if the tool is pressed very hard or if the metal is interspersed with harder particles.

If even one of the teeth breaks, it is better to immediately change the blade, because others will break behind it. You can use the old one, but then it will need to be restored first. To do this, the nearest teeth are ground near the broken tooth. It will be enough to grind off two or three. After this procedure, you can use the canvas again.
