It carries a 90-degree square shape, a neutral hand orientation, and a negative rake angle of 6 degrees with chamfered and honed cutting edges. The inscribed circle measures 0.5000 inches, insert length is 0.5000 inches, thickness is 0.1875 inches, and the corner radius is 0.0313 inches. Eight cutting edges are available per insert, providing significant index life on qualifying operations. This insert belongs to the KENLOC series and is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for turning, facing, and boring operations on steel, stainless steel, and superalloys including titanium. The MP chip breaker geometry supports both roughing and medium machining applications. The KCM25B grade delivers high toughness on steel workpieces and moderate wear resistance combined with toughness on stainless steel. Maximum depth of cut reaches 0.1665 inches. The insert is held by clamp or pin methods and is compatible with negative-style SNMG toolholders operating within the ANSI size code 432 and ISO size code 120408 specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, and TiOCN for wear resistance across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges per insert for extended index life and lower per-edge cost\u003c\/li\u003e\n  \u003cli\u003eMP chip breaker geometry rated for both roughing and medium machining\u003c\/li\u003e\n  \u003cli\u003eKCM25B grade optimized for steel and stainless steel with high toughness characteristics\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert accepts clamp or pin holding methods in SNMG-compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards: ANSI SNMG432, ISO SNMG120408\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in negative-style SNMG toolholders conforming to ANSI size code 432 and ISO size code 120408.
