Manufactured from solid carbide and coated with TiAlN via a PVD process under the AH120 grade designation, this insert delivers wear resistance and thermal stability across a range of workpiece materials. The insert features an 80-degree diamond shape, a neutral hand orientation, and a chamfered and honed cutting edge style. With four usable cutting edges and a negative rake geometry, it is suited for moderate to heavy interrupted and continuous cuts on steel and related alloys. Licensed machinists and CNC setup techs are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is rated for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, corresponding to ISO material codes P, M, K, S, and H. It is appropriate for turning, facing, and boring operations in both production and job-shop environments. The TH chip breaker geometry is engineered to manage chip flow at moderate cutting parameters across these material groups. Applicable material grades include P15, P25, M15, M25, K15, K30, S10, and S25.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating under AH120 grade for heat and wear resistance on difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) with negative rake angle of -20 degrees for stable, rigid cutting\u003c\/li\u003e\n\u003cli\u003eFour cutting edges with chamfered and honed edge prep for reliable edge strength\u003c\/li\u003e\n\u003cli\u003eTH chip breaker design for effective chip control across steel, stainless steel, cast iron, superalloys, and hard materials\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with standard CNMG toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code CNMG 643 TH\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct fitment for standard CNMG 643 TH toolholder pockets conforming to ANSI and ISO specifications.
