KC9240 inserts offer an extraordinary combination of toughness, built-up edge resistance, and wear resistance in stainless steel applications. Excellent thermal/mechanical shock resistance makes KC9240 inserts ideally suited for even the most challenging stainless steel applications. | | | | | | KC9240 | | | | | | | | | | | | | | improved | | | | | | C1 - C2 | | | | | | | | | | | | | | | | | | | | | | | | composition: A multi-layered K-MTCVD coating over a super-tough substrate. application: This K-MTCVD coated carbide grade is engineered to take on the most brutal cast stainless steel machining applications. Its substrate withstands heavy interruptions, while its polished surface resists build-up, even at slow cutting speeds. Additionally, its wear-resistant coating resists the micro-chipping common when machining austenitic stainless steel. KC9245 grade is also available in insert sizes and geometries appropriate for heavy feeds and large depths of cut. | | | | | | o zu o p | | | | | | | | | | KC9245 | | | | | | | | | | | | | | C1 - C2 | | | | | | | | | | | | | | | | | | | | CÛ ce ai m ce m LU 3 o | | | | | | composition: A multi-layered CVD coating with very thick K-MTCVD Al2C>3 TiCN layers, for maximum wear resistance, is applied over a substrate specifically engineered for cutting cast and ductile irons. application: The KC9315 grade delivers longer tool life when high-speed machining of ductile and cast irons. The thick K-MTCVD TiCN coating ensures a tremendous tool life advantage, especially when cutting higher tensile strength ductile and cast irons where workpiece size consistency and reliability of tool life are critical. This new Kennametal grade is excellent when used for either straight or lightly interrupted cut applications. Moreover, if you're looking for high productivity performance, the KC9315 grade is an ideal choice. | | | | | | KC9315 Ä improved | | | | | | | | | | ■a 15 nj u | | | | | | TIN Al203 MT-TiCN | | | | | | z 3 | | | | | | | | | | ■a <v nj o u à > u | | | | | | un | | | | | | | | | | | | | | | | | | | | | | | C3 - C4 | | | | | | | | | | | | | | | | | | | | o en | | | | | | | | | | composition: A TiCN and alumina-coated grade with a strong, reliable substrate. application: Grade development for the KC9325 grade focused on a variety of ductile and cast iron operations. The coating and substrate are optimized for flexibility. If you are machining different types of ductile or cast irons where application confidence, flexibility and broad range reliability are your primary requirements, the KC9325 grade is the perfect choice. | | | | | | | | | | C | | | | | | KC9325 | | | | | | | | | | | | | | | | | | C2 - C3 | | | | | | | | | | | | | | | | | | | | composition: A tough cobalt-enriched substrate with a multilayered CVD coating. application: KU30T is a new grade designed specifically for the job shop industry where a wide range of workpiece materials is employed. With its tough cobalt-enriched substrate, KU30T performs very effectively in roughing through finishing operations. The post-coat grinding of the insert permits stable insert seating while the post-coat treatment resists workpiece build-up and microchipping. For machining steels, cast irons, and stainless steels, your first choices are the -RN, -MN, and the -RP geometries. For medium machining and finishing, the -MP and -FP geometries with a positive rake are suggested. | | | | | | KU30T | | | | | | | | | | | | | | C5 - C6 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PVD-Coated Cermet | KT315 | TiN | composition: A multi-layered, PVD TiN/TiCN/TiN, coated cermet turning grade. application: Ideal for high-speed finishing to medium machining of most carbon and alloy steels and stainless steels. Performs very well in cast and ductile iron applications too. Provides long and consistent tool life and will produce excellent workpiece finishes. | P | | | | | | | | | | | | | | M | | | | | | | | | | | | | fu | K | | | | | | | | | | | | N | | | | | | | | | | | | | S | | | | | | | | | | | | C3, C7 | H | | | | | | | | | | | Ceramics | KY1310 | | composition: An advanced sialon ceramic grade. application: Grade KY1310 provides maximum wear resistance.
