It features a PVD-applied TiAlN coating that provides thermal and wear resistance for demanding cutting operations. The insert has an 80-degree diamond shape, a neutral hand orientation, a 0.25-inch inscribed circle, and a corner radius of approximately 0.008 inches. It is held in place by a screw-type clamping system and is designed for use in CNC and manual turning operations. Licensed machinists, CNC setup technicians, and tooling specialists work with this insert in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for turning, facing, and boring applications. Its primary workpiece material targets are stainless steel, superalloys, titanium, and hard materials, corresponding to ISO material grades M01, M10, S01, and S10. The PS chip breaker geometry and positive rake angle of 10 degrees support controlled chip formation and reduced cutting forces when machining these challenging materials. The insert delivers two cutting edges per unit, extending tool life between index cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating applied via PVD process for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with positive rake for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003ePS chip breaker geometry optimized for stainless steel, superalloys, and hard materials\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for extended service between replacements\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping on difficult workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CPMT-style screw-on turning toolholders conforming to ANSI and ISO standards for CPMT 21.50.5 inserts.
