Kennametal A4-GMN Inserts

Grooving and turning insert with A4 tooling for turning, facing, grooving, face grooving and cut-off applications across a broad range of workpiece materials. The unique clamping system and versatile insert geometry deliver the highest metal removal rates in the industry. a tough cobalt enriched carbide grade with a newly designed multilayer MTCVD-TiCN-Al2O3 coating with superior interlayer adhesion. Best general purpose turning grade for most steel and ferritic and martensitic stainless steel. The substrate design ensures adequate deformation resistance with excellent insert edge strength. Coating layers offer good wear resistance over a wide range of machining conditions and the post coat treatment minimises microchipping and improves coating adhesion to substrate leading to long tool life and improved workpiece finishes. Screw-On 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.
