Carrying the ANSI\/ISO designation APMT1604PDR and manufactured to grade WU20PM, this insert features a TiAlN coating applied via PVD process, delivering thermal resistance and wear protection in demanding cutting environments. The parallelogram insert shape, positive rake geometry, and honed cutting edge work together to reduce cutting forces and maintain edge integrity on difficult workpiece materials. With 2 cutting edges and screw-in holding, it is a direct drop-in for compatible indexable milling toolholders used by machinists and tooling technicians in production and job-shop settings.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling steel, stainless steel, superalloys, and titanium as primary workpiece materials, with secondary suitability for cast iron and hard materials. The positive rake and 11-degree relief angle suit finishing and semi-finishing passes where controlled chip formation and surface finish matter. The APMT1604PDR is compatible with the CIP cutter series and is a right-hand cut configuration. It is sized for insert size code 1604, with a maximum depth of cut of 0.6689 inches and an inscribed circle of 0.3638 inches, making it a standard choice for medium-duty indexable milling on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN PVD coating for heat and wear resistance in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003eAPMT1604PDR ANSI\/ISO designation  -  direct replacement for same-spec inserts in CIP-series cutter bodies\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with 11-degree relief angle reduces cutting forces on difficult alloys\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style provides consistent edge prep for reliable chip formation\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert, single-sided, right-hand orientation\u003c\/li\u003e\n  \u003cli\u003eScrew-in holding method for secure, repeatable seating in indexable toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CIP-series indexable milling cutter bodies accepting APMT1604PDR-style inserts.
