Manufactured to the VNMX insert style with a 35-degree diamond shape, this insert features a 3\/8-inch inscribed circle, a 1\/64-inch corner radius, and an uncoated PCD cutting edge. The DA1000 material grade delivers exceptional wear resistance and edge retention on aluminum, copper, and other non-ferrous workpiece materials. Rated for neutral cutting direction with a negative rake angle and zero relief angle, it is suited for stable, repeatable turning operations. CNC machinists and toolroom technicians install this insert into compatible VNMX-style toolholders for production and precision turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning operations on non-ferrous metal workpieces, including aluminum alloys and copper-based materials where PCD tooling is the standard choice for extended tool life and superior surface finish. The VNMX331GD geometry with the X chip breaker designation accommodates a range of depth-of-cut and feed conditions typical in high-volume CNC turning. It is equally applicable in job-shop and production environments where consistent edge performance is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolycrystalline Diamond (PCD) cutting material grade DA1000 for non-ferrous machining\u003c\/li\u003e\n\u003cli\u003eVNMX insert style with 35-degree diamond shape and neutral cutting direction\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 1\/64-inch (0.1560-inch) corner radius\u003c\/li\u003e\n\u003cli\u003eUncoated edge with negative rake angle and zero clearance for controlled chip formation\u003c\/li\u003e\n\u003cli\u003ePin and screw insert holding method for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eComplies with ANSI and ISO 13399 standards; ANSI Code NFVNMX331GD, ISO Code NF-VNMX160404N-GD\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VNMX-style turning toolholders compatible with the 331 insert size code.
