It features a 35-degree diamond insert shape with a neutral hand orientation and a honed cutting edge style. The insert carries a 0.0157-inch (1\/64 inch) corner radius and an inscribed circle diameter of 0.375 inches. With four usable cutting edges and a negative rake angle of -20 degrees, it is designed for productive material removal in precision turning operations. Machinists and CNC lathe operators working in job shops and production environments install this insert on compatible toolholders using clamp and pin holding methods.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It carries material grade designations M10, M20, S10, and S20, making it applicable across ISO material groups P, M, K, N, S, and H. Typical applications include turning, facing, boring, back turning, and back boring. The HRF chip breaker geometry is optimized for finishing and medium cuts on these diverse material types. It is well-matched to production CNC turning centers and manual lathes where consistent chip control is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating on AH8015 carbide grade for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V) insert shape provides a sharp approach angle for profiling and contour turning\u003c\/li\u003e\n  \u003cli\u003eHRF chip breaker geometry supports finishing to medium-depth cuts with reliable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert reduce per-edge tooling cost in production environments\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows use on standard right-hand and left-hand toolholders depending on setup\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.059 inches suits finish and semi-finish turning passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit insert for VNMG-style toolholders conforming to ANSI and ISO insert standards.
