Manufactured to the GCM3002GF geometry in Sumitomo grade AC530U with a Super ZX PVD coating, this neutral-hand insert delivers a 3 mm cutting width and a maximum depth of cut of 20 mm. The AC530U grade is engineered for wear resistance and toughness in steel and stainless steel applications. With a 7-degree relief angle and a 0.20 mm corner radius, this insert is suited for tight-tolerance grooving where surface finish and dimensional control are critical. It is installed using a clamp-style holder and carries 2 cutting edges per insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in production turning environments where consistent groove geometry and extended tool life are priorities. It is appropriate for grooving ferrous materials including carbon steels, alloy steels, and stainless steels. The GF chip breaker geometry promotes controlled chip evacuation in medium-depth grooving cuts. Machinists and CNC tooling technicians working in job shops, contract manufacturing, and production machining facilities are the primary installers of this insert. The GND series designation identifies the holder system compatibility family for correct seating and clamping.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with AC530U grade for wear and thermal resistance\u003c\/li\u003e\n  \u003cli\u003eSuper ZX PVD coating for improved surface finish and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003e3 mm cutting width with 20 mm maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003eGF chip breaker for controlled chip formation in grooving operations\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible setup on compatible holders\u003c\/li\u003e\n  \u003cli\u003e0.20 mm corner radius for precise groove corner geometry\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert for extended service life per unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GND series clamp-style grooving holders that accept GCM3002 insert size.
