Advanced Material Inserts Grades and Grade Descriptions Reduce cycle times. High speed and feed capability. Long tool life. New multi-layer coating provides better wear resistance. P Steel M Stainless Steel K Cast Iron N Non-Ferrous S High-Temp Alloys H Hardened Materials wear resistance 05 10 15 20 25 30 35 40 45 Grade Description Coating Mixed (black) ceramic. Matrix Al2O3 and TiCN. Good toughness properties combined with good wear resistance. Semi-fi nishing and fi nishing. For hardened iron base materials and grey cast iron (fi nishing). CM-H10 toughness K H Silicon-nitride ceramic. Extraordinary toughness properties. Roughing, also in heavily interrupted cuts. Capable of high-performance turning. To be used with or without coolant. For grey cast iron. K CN-K15 Whisker ceramic with a matrix of Al2O3 + SiCw. The SiC whiskers embedded in the micro-structure give this ceramic excellent toughness for cutting high-temp alloys and cast materials with high Brinell hardness. S C4 H A high CBN content, solid CBN insert with multiple cutting edges. Applied in roughing to fi nishing of fully pearlitic grey cast iron, chilled irons, high-chrome alloyed steels, sintered powdered metals, and heavy cuts in hardened steels (>45 HRC). Use for fi nishing chilled and fully pearlitic cast iron. Solid inserts offer better security and shock-resistance than tipped inserts, while also enabling deeper depth-of-cut capability. BN-K40 H H B173 A low content CBN grade with a PVD-TiAlN coating for added wear resistance. Designed for precision machining of hardened steels (>45 HRC); the harder the steel the better. PVD coating offers improved wear resistance and excellent surface fi nish capability. Effectively applied on bearing steels, hot and cold work tool steels, high-speed steels, die steels, case-hardened steels, carburised and nitrided irons, and some hard coatings. BN-H10 widia.com K
