Turning insert with a multilayer TiN-MT-TiCN-Al2O3 CVD coating over a super tough substrate. The KCM35 grade is engineered to take on the most brutal cast stainless steel machining applications. The substrate withstands heavy interruptions while the coating provides the wear resistance needed for long tool life. The polished surface resists edge build-up even at slow cutting speeds. KCM35 grade is available in insert sizes and geometries appropriate for heavy feeds and large depths of cut. 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.
