SNMM856SR WP25CT Widia/Kennametal SNMM250724SR WP25CT Square Negative Carbide 0.0940 2.39mm Radius Roughing, Medium

WIDIA SNMM250724SR WP25CT Negative Square Insert Roughing, Medium A tough cobalt-enriched carbide grade with a newly designed multilayer K-MTCVD TiCN-Al2O3-TiCNTiN coating with superior interlayer adhesion. This is the industry’s best general-purpose turning grade for most steels and ferritic and martensitic stainless steels. The substrate design, with cobalt-enrichment, ensures adequate deformation resistance along with excellent bulk toughness and insert edge strength. The coating layers offer good wear resistance over a wide range of machining conditions. The smoothness of the coating leads to reduced frictional heat, minimizes microchipping, and improves workpiece surface finishes.
