It carries a multilayer CVD coating — TiC, TiCN, and TiN — classified as grade TP40, which delivers high toughness on steel (P) and stainless steel (M) and moderate wear resistance on hardened materials (H). The insert features an 80-degree diamond (rhombic) shape with a positive rake and positive side clearance, a 3\/8-inch inscribed circle, a 1\/32-inch corner radius, and an F2 chip breaker geometry optimized for finishing cuts. Installation is screw-held. Licensed machinists and CNC setup technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing passes in boring, facing, and turning applications on CNC lathes and turning centers. Its F2 chip breaker geometry controls chip flow at light-to-moderate depths of cut, making it well-matched for close-tolerance finish work on steel and stainless steel components in general machining, aerospace, and fabrication environments. The neutral hand orientation gives it flexibility across a range of tool holders that accept CCMT-style inserts. It meets both ANSI and ISO dimensional standards, with ANSI code CCMT32.52 and ISO code CCMT09T308.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating (TiC, TiCN, TiN) at grade TP40 for high toughness on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eF2 chip breaker geometry optimized for finishing operations\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive rake and positive side clearance\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert; screw-held mounting method\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for smooth, consistent finish on workpiece surface\u003c\/li\u003e\n  \u003cli\u003eDual compliance with ANSI (CCMT32.52) and ISO (CCMT09T308) standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for CCMT-style screw-on tool holders accepting an 80-degree diamond insert with a 3\/8-inch inscribed circle and M-tolerance class.

Power down and lock out the spindle before seating or indexing inserts. Seat the insert fully against the pocket locating surfaces before tightening the clamping screw to ensure consistent tool geometry.
