Turning insert with a multilayer MTCVD-TiCN-Al2O3-TiOCN coated carbide grade. An excellent finishing to medium machining grade for austenitic stainless steel at higher speeds and covers a broad range of steel applications in the P20-25 range. KCM15 grade in combination with unique geometries have been designed to resist depth of cut notching and minimize burr formation. The post coat treatment reduces coating stresses, improves coating adhesion, minimizes microchipping and edge build-up and improves workpiece finish. 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.
