composition: A CVD tri-phase coating on an extra-strong, cobalt-enriched
alloyed substrate.
application: Designed for heavy cutting of low-, medium-, and high-carbon
steels, medium hardness alloy and tool steels, stainless steels, and some
high-temperature alloys. Excellent thermal and mechanical shock resistance
makes grade KC850 ideally suited for difficult drilling applications.
Used in inserts for Kendex/Metcut drill bodies.
