'Composition: A tri-phase coating on an extra strong, cobalt-enriched substrate. 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.'
