Turning insert with a new PVD multilayer AlTiN + AlCrN coated carbide with an excellent combination of wear resistance and coating strength. The KCK20 grade is specifically engineered to maximize coating adhesion and edge strength making this grade ideal in wet interrupted cutting of grey and ductile irons and can also be used in dry conditions. It can be used in a wide range of applications from finishing to roughing, to maximize productivity wherever strength and reliability are needed. 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.
