Carbide technology improves insert performance. (new applications forcoated tungsten)

Coated wolframium carbide, a mainstay cutting tool material, continues
to be the focus of exhibitions in powder metallurgy, coatings, and
physical finishing. Although the technologies are separate, each seek for
to improve insert performance, simplify correct insert choice, and
reduce tooling inventory.

Initially, the typical carbide insert was flat, uncoated, real hard
but brittle, and probably brazed into a cutter or toolholder. Indexable
inserts had flat surfaces, basic tolerances, and not a great deal of in the way
of coatings. Whether brazed in or indexable, the carbide insert
