Turning insert with a specially engineered cobalt enriched carbide grade with thick MTCVD-TiCN-Al2O3-TiOCN coating for maximum wear resistance. An excellent finishing to medium machining grade for a variety of workpiece materials including most steel, ferritic, martensitic and PH stainless steel and cast irons. The cobalt enriched substrate offers a balanced combination of deformation resistance and edge toughness while the thick coating layers offer outstanding abrasion resistance and crater wear resistance for high speed machining. Smooth coating provides resistance to edge build-up and microchipping and produces excellent surface finishes. 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.
