It features a triangular insert shape with a 60-degree included angle, a PVD coating in grade ACM25P, and a neutral hand orientation. The insert provides six usable cutting edges, maximizing tool life per insert. A corner radius of 0.0157 inches (0.40 mm) and a maximum depth of cut of 0.1654 inches (4.20 mm) make it well-suited for finishing and semi-finishing operations. Licensed machinists and CNC operators install and index this insert as part of standard toolholder maintenance.\u003c\/p\u003e\u003cp\u003eThis insert is rated for use on steel (P-class), stainless steel (M-class), and special and super alloys (S-class). The ACM25P grade balances wear resistance and toughness across these material groups, making it a versatile choice for job shops and production environments running mixed-material workpieces. It seats in TNMG-compatible clamp, lever lock, pin, or screw-style toolholders and is sold individually with a minimum order of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTNMG331 ANSI code \/ TNMG160404 ISO code  -  direct cross-reference for international tooling systems\u003c\/li\u003e\n\u003cli\u003ePVD-coated carbide in grade ACM25P for extended edge life on steel and stainless\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert reduce per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits left- or right-hand toolholder setups\u003c\/li\u003e\n\u003cli\u003eIPK+ chip breaker geometry promotes reliable chip control in turning operations\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, lever lock, pin, and screw insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style turning toolholders that accept a triangular insert with a 0.1874-inch thickness, a 0.3752-inch inscribed circle, and a 0.1512-inch hole diameter.
