Turning insert with advanced PVD-AlTiN coated fine-grained tungsten carbide grade. The KCS10 grade specifically engineered for the productive machining of high temperature alloys. The fine grained tungsten carbide substrate has excellent toughness and deformation resistance while the advanced PVD coating allows metal cutting speeds double those of conventional PVD coated cutting tools. inserts are the first choice for I.D. turning of all materials and O.D. turning on small to medium lathes. Available in ﬂat top and chip control geometries with both moulded and ground peripheries. Suitable for all workpiece materials.
