Turning insert with a multilayer coating with moderately thick MTCVD TiCN-Al2O3 layers over a highly deformation-resistant carbide substrate. Designed for high-speed machining of grey and ductile irons. The substrate and coating architecture together with CW5 post-coat treatment ensure a tremendous tool life advantage especially when cutting higher tensile strength ductile and grey irons where workpiece size consistency and reliability of tool life are critical. Excellent both in straight and varied depths of cut. 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.
