Illustration of Inserts

Cutting inserts which are reversible to reveal a new cutting edge

Inserts are made by pressing and sintering of cemented carbide powder (most common) or ceramic powder, see more under Materials in cutting tools. THE NAME REFERS TO THE INSERT'S CAPABILITY TO BE re-positioned to use several of the different cutting edges of the insert before discarding.

The inserts are available in a variety of shapes and designs for cutting different materials and desired geometries.
