Introduce:

The cutting, punching and shearing of metallic and non-metallic materials belong to the most demanding tasks cold-work tool steel tools are subjected to. Besides cutting and shearing, there are virtually no other applications where the tool's properties have such an influence on the process.

Application
(1) Cutting tools for processing various external surfaces: including turning tools, planing tools, milling tools, external surface broaches and files, etc..
(2) Boring tools: including drills, reaming drills, boring tools, reamers and inner surface broaches.
(3) Thread processing tools: including taps, flanges, automatic thread cutters, thread turning tools and thread milling cutters.
(4) Gear machining tools: including hobs, gear cutters, shaving tools, bevel gear machining tools, etc..
(5) Cutting tools: including toothed circular saw blades, band saws, bow saws, cutting tools for turning and saw blade cutters, etc.
