C-Class

z D

composition: KY1540 is the latest and most advanced sialon material

ever developed.

application: Combines excellent wear properties, fracture toughness, and thermal shock resistance for general purpose to finish machining of high-temperature alloys. Provides superior depth of cut notch resistance as compared to whisker ceramics.

C4

composition: An advanced alumina/TiC ceramic grade (black). application: Great combination of toughness and wear resistance; used for machining alloy steels, tool steels and stainless steels to 60 HRC (653 HB). It is also applied in finish turning and boring of cast irons.

C4, C8

composition: An advanced sialon grade.

application: Good mechanical shock resistance combined with edge wear resistance; used for general purpose machining of high-temperature alloys.

C3

composition: Pure silicon nitride grade.

application: Maximum toughness; used at high feed rates for rough machining of gray cast iron, including machining through interruptions.

C2

composition: A PVD TiN coating over an aluminum oxide and titanium carbonitride ceramic (Al2O3/TiCN).

application: Used for finish turning of hardened steels and irons (greater than 45 HRC). Where possible, use under dry conditions in smooth or varied depth of cuts. Can also be applied in finish turning of nickel alloys, cobalt alloys, and powder metals.

C4, C8

composition: A PVD TiAlN coating over a low content, PCBN tip brazed onto a carbide insert.

application: Designed for roughing to finishing of hardened steels (>45 HRC). Use on bearing steel, hot and cold work tool steels, high-speed steels, die steels, case hardened steels, carburized and nitrided irons, and some hard coatings.

C4, C8

z

composition: A low content PCBN grade with a TiN/Al₂O₃/TiCN CVD coating for protection against harmful crater wear. application: KB9610 is designed for the precision machining of hardened steels (>48 HRC), the harder the steel the better. KB9610 is very effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case hardened steels, carburized and nitrided irons, and some hard coatings. Do not use on soft steels. For best results, apply negative rake tools in OD applications and positive tools in ID applications. KB9610 is available in a multi-tip format with a tremendous breadth of edge preps and two styles of wiper geometries.

C4, C8

composition: A high CBN content, solid PCBN structure having multiple cutting edges and a CVD alumina coating.

application: KB9640 grade is applied in the roughing to semi-finishing of fully pearlitic gray cast iron, chilled irons, high chrome alloy steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Also use for finished chilled cast iron and fully pearlitic cast iron. Do not apply on finishing hardened steels. The solid KB9640 also can be effectively applied when roughing hardened steels.
