KC850 – turning & boring, profiling, grooving C5 – C6 M30 – M45 and P25- P45
Composition: A tri-phase coating on an extra strong, cobalt-enriched substrate.
Three coating layers; TiN outside, TiCN middle, TiC inside
Application: Grade KC850 has long been considered the industry’s leading choice
for general purpose machining of many workpiece materials. With the advent of higher
machine tool spindle speeds, today it finds its best application in heavy cutting of low,
medium, and high carbon steels, as well as medium hardness alloy and tool steels.
Excellent thermal and mechanical shock resistance makes grade KC850 ideally suited
for difficult applications with interruptions. Consider using grade KC935 for lighter cuts.
