composition: An advanced PVD coating over a tough and highly wear resistant carbide substrate.

application: KU25T is ideal for finishing to general machining of most workpiece materials. With a higher cobalt content than KU10T, this grade provides the toughness needed to handle the demands of grooving, threading and cut-off operations. KU25T performs extremely well when machining most steels, stainless steels, cast irons, non-ferrous materials, and superalloys under stable conditions. KU25T can also be effectively applied when machining hardened and short-chipping materials.

composition: A newly developed, advanced cobalt-enriched carbide grade with a thick alumina coating.

application: A versatile performer on a wide range of workpiece materials (steels, stainless steels, and cast irons) for roughing through finishing operations. This highly wear-resistant grade can operate with or without coolant at high speeds, and has exceptional edge strength for interrupted cuts. The micro-finished insert edge resists workpiece build-up and microchipping, and produces excellent surface finishes. For machining steels and cast irons, your first choices are the -RN and -MN geometries. For medium machining applications and finishing cuts, the -MP and -FP geometries with a positive rake are suggested.

composition: An alumina-coated grade with a tough cobalt-enriched substrate.

application: For heavy roughing applications on all types of steels, stainless steels, and most other materials when tool edge strength is critical. A specially designed coating preparation assures prolonged tool life. Apply with confidence on tough jobs.

composition: A specially engineered, patent-pending cobalt-enriched carbide grade with thick K-MTCVD-TiCN coating layer, an Al2C>3 layer of controlled grain size, and outer layers of TiCN and TiN for maximum wear resistance.

application: An excellent finishing to medium machining grade for a variety of workpiece materials including most steels, ferritic and martensitic stainless steels, and cast irons. The specially engineered, 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. The smooth coating provides good resistance to edge build-up and microchipping and produces excellent surface finishes. For rougher cutting, use the KC9125 grade.

composition: A tough cobalt-enriched carbide grade with a newly designed multi-layer K-MTCVD TiCN-Al₂O₃-TiCN-TiN coating with superior interlayer adhesion.

application: 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, assures 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. The KC9125 grade performs well in moderately heavy roughing to semi-finishing cuts. Use the KC9110 grade for finishing cuts.

C2 - C3, C6 - C7

composition: A newly engineered, tough carbide grade with an advanced multi-layered TiN-MT-TiCN-A^C^-TiN coating. application: For heavy roughing applications of alloy steels where insert edge strength is critical. A specially designed coating ensures excellent interlayer adhesion and long tool life.

C5 - C6

composition: A newly engineered, patent-pending, multi-layered K-MTCVD coated cobalt-enriched carbide grade. application: KC9225 grade has been specially designed for resisting depth-of-cut notching and minimizing burr formation often observed in the machining of austenitic stainless steels. Cobalt-enrichment provides an optimum combination of toughness and deformation resistance. This new grade's polished edge minimizes build-up and ensures superior workpiece finishes. KC9225 inserts are your first choice for machining stainless steels.
