According to GOST for reinforcement of the instrumentation used steel, containing cobalt at least 3%. But if cobalt is contained in an amount of more than 20%, the carbide becomes brittle, there is increased wear of the tool. The use of solid alloys requires careful observance of the production technology.
The manufacture of the tool for machining parts, made of structural steel, when working through shock, interrupted cuts. Such tools can be used for processing titanium alloys and stainless steel, heat-resistant and high-strength steel.
According to GOST surface carbide inserts — brushed, smooth, free of cracks, grease, burrs, chips, stains grease.
