Cutting Tool

A hardened piece of metal that is machined and ground so that it has the shape and cutting edges appropriate for the operation for which it is to be used.


Cutting tool materials include cemented carbides, ceramics, cermets, polycrystalline diamond, polycrystalline cubic boron nitride, some grades of tool steels and high-speed steels.

Wear Resistance

Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
