Turning insert with a multilayer CVD coating comprised of TiN-MT-TiCN-Al2O3 layers over a tough cobalt enriched carbide substrate. This CVD coated grade is designed for general purpose machining of austenitic stainless steel at moderate speeds and feeds. KCM25 inserts offer an extraordinary combination of toughness, built-up edge resistance and wear resistance in stainless steel applications. 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.
