Making various crafts and creating products from metals, wood or glass requires some necessary tools. Among them are files. They can be of various types. Today we will focus on the features of triangular models.

Characteristic

Such construction devices, which are more often referred to simply as triangles, are considered quite popular along with the flat and round varieties. So, they can be used in the same majority of cases where other types of files are used.

Triangles represent a simple structure, in which the working part looks like a metal section with notches … Moreover, their shape can differ significantly. The rod, made of metal, attaches directly to the handle.

The basic requirements for the manufacture of these types of files can be found in GOST 3749-77. There, among other things, the requirements for the material from which such products are made are fixed.

It should belong to the hypereutectoid group, since only such bases can be subjected to the necessary hardening.

Views

This file is produced in various designs. All of them can be classified into several main groups, depending on the type of notch.

Let's consider each variety separately

• Single cut . These models are most often used in the processing of inner corners of non-ferrous metals, but they are often taken for other purposes. This type is quite common. The notch itself is presented in the form of small teeth, which are placed in a certain sequence. As a rule, high-carbon steel or special iron alloys are taken for its manufacture. In any case, the metal must undergo a special heat treatment, which allows you to maximize the level of hardness.
• Cross cut . Such varieties are produced with a special cross structure, which must be placed at a certain angle (the main part is at an angle of 65 degrees, the additional part is at an angle of 45 degrees). These triangular files are most often purchased for deep processing of corners, which are made from cast iron, steel or bronze base.
• Arc, point models of notches . These types of files are taken when working with products made from various types of wood. Moreover, they can be used for both roughing and finishing work.
• Stamped notches . These types of triangles can be purchased for leather and rubber materials, so they are primarily used in carpentry rather than plumbing.

Special attention should be paid to a special type of triangular tools - diamond-coated models. Similar patterns can be produced with different types of notches.

Products with this application are coated with special diamond grit . These triangles are mainly used in the processing of glass surfaces; they are also often used for working with hardened steel, ceramic objects, and especially hard metal alloys.

Dimensions (edit)

Triangles can be of various sizes. They will be determined by the type of work being done. Cross-sectional shapes and measured lengths are also different.

But most often in hardware stores samples are presented with a working part length of:

• 150 mm;
• 160 mm;
• 200 mm;
• 300 mm;
• 350 mm.

Appointment

Triangles are widely used in the processing of a wide variety of materials. They allow you to carefully cut off the top layer, while making translational movements. With the help of such tools, it is quite possible to remove layers of old paint and various stubborn dirt.

Models for metal are sold separately, which allow for the most thorough and deep processing of these surfaces. They are made from the hardest and most resistant materials. Most often they are made with a diamond coating.

In addition, they are suitable for turning various parts to give them the required dimensions. Triangles are sometimes used for simple sharpening of other construction tools, including hacksaws, stylet, and stripping contacts in electrical equipment. With these files, you can easily polish metal surfaces.

Choice

When choosing a suitable triangular file, it is worth taking into account some important selection criteria. So, remember that it is necessary to correlate the dimensions of the tool with the dimensions of the material that will be further processed.

Moreover, in the process of filing, the entire working surface of the file should be used at once.

Also keep in mind that according to the number of the notch, the device is selected depending on the size of the allowance to be removed … So, for rough processing of surfaces, they most often take models numbered 0 and 1. For finishing, you can purchase sample No. 2, and for finishing filing, use samples No. 3, 4, 5.

Before buying a triangular file, pay attention to the material from which it is made. An excellent option would be models made of high-quality steel base, while its surface must be additionally coated with special protective compounds that will significantly extend the service life of the tool.

Pay attention to the handle of the products. A file with a wooden handle is considered the most convenient for a person. It will not slip out of the hand during long processing. As a rule, ash, maple, linden or birch wood is used to create this part. Pressed paper can also be used.
