Technical Files

Technical files are the largest group of files, also known as locksmith files or shop files. These tools are designed for filing metals and hard plastics. They are mostly used in metalworking and machining of metal castings, hard plastics, laminates, etc.

Construction of technical files

Technical files are simple in design. Their parts are the working part and the handle. On the working part, technical files have densely cut blades of different shapes. There are four basic types of cut: single-row, unidirectional and multi-row, bi-directional and single-row, multi-directional and multi-row. The surface density of the cuts is determined by their graduation, which gives the number of blades per 1 cm. The working part of files is made of carbon tool steel. Technical files are available with wooden or 1- or 2-component plastic handles.

Types of technical files

According to the basic classification of files according to their pitch, we distinguish between the following technical files numbered 0-5: 0 - coarse, 1 - coarse, 2 - medium, 3 - fine, 4 - double fine, 5 - silk.
