This is a new factory pack of 4 Kennametal SNMG150612RN (ANSI equivalent SNMG543RN) carbide turning inserts in grade KCP25B. Decoding the ISO designation: S = square 90° shape, N = 0° clearance angle (negative rake), M = tolerance class M, G = chipbreaker with central mounting hole, 15 = 15.875 mm inscribed circle, 06 = 6.35 mm thickness, 12 = 1.2 mm nose radius, RN = round-nose/full-radius chipbreaker geometry optimized for medium-to-rough turning. KCP25B is Kennametal's CVD multi-layer coated (TiCN/Al₂O₃/TiN) cemented carbide grade targeting ISO P25 steel turning applications, offering robust wear resistance and thermal barrier properties for interrupted and continuous cuts at medium-to-high feeds. These inserts are compatible with SNMG-style toolholders (e.g., Kennametal DSSNR/L, MSSNR/L series) and are manufactured in the USA, suitable for turning carbon steels, alloy steels, and ductile cast irons under wet or dry conditions.
