Turning insert with a CVD tri-phase coating on an extra-strong, cobalt-enriched alloyed substrate. Designed for heavy cutting of low medium and high-carbon steel, medium hardness alloy and tool steel, stainless steel 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. Kenloc insert is the ﬁrst choice for general machining of all materials on medium to large lathes. Kenloc inserts offer the best economy for high metal removal rates. available in ﬂat top and chip control geometries with both moulded and ground peripheries. Suitable for all workpiece materials.
