Coated with a multilayer TiCN and Al2O3 CVD coating via MTCVD process, this insert is built for moderate-to-high wear resistance and toughness. It features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and an MP chip breaker geometry suited for roughing and medium machining passes. With four cutting edges and negative rake geometry, it delivers consistent performance across a range of metal-removal applications. Machinists and CNC lathe operators working with steel and stainless steel will find this insert well-matched to demanding production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring of steel, stainless steel, and superalloys including titanium-bearing workpiece materials. It is classified under primary workpiece material codes P and M, with secondary classification S for superalloys. The MP chip breaker geometry supports both roughing and medium machining cuts. The KENLOC series designation indicates compatibility with KENNAMETAL KENLOC-style insert holders that accept CNMG-style inserts secured by clamp or pin holding methods. This insert is appropriate for production CNC turning centers in both light industrial and heavy-duty shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCM15 grade with multilayer TiCN and Al2O3 CVD coating for wear resistance in steel and stainless steel cutting\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (CNMG) with negative rake and 0-degree relief angle for strong cutting edge support\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits a wide range of CNMG-compatible KENLOC toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO insert standards (ANSI: CNMG543, ISO: CNMG160612)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL KENLOC series toolholders that accept CNMG-style inserts with clamp or pin holding.
