It features a triangular insert shape with a 60-degree included angle, a 1\/2-inch inscribed circle, and a 1\/64-inch corner radius. The insert is 3\/16 inch thick and 0.8661 inches in length, with 6 cutting edges available per insert. The MR4 chip breaker geometry and T-Land cutting edge style make it well-suited for stable chip control during roughing and finishing passes. Licensed machinists and CNC tooling technicians are the primary installers and users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning, facing, boring, and back turning operations on superalloys and titanium as the primary workpiece materials, with secondary suitability for steel, cast iron, non-ferrous materials, and hardened materials. The uncoated carbide substrate in grades S10, S20, and S30 is optimized for cutting heat-resistant alloys where coating adhesion or thermal insulation is less critical than edge sharpness and substrate toughness. It is a neutral-hand insert, making it usable on both left- and right-hand toolholders where TNMG-style seating is supported.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide uncoated substrate in grades S10, S20, and S30 for superalloy and titanium cutting\u003c\/li\u003e\n\u003cli\u003eMR4 chip breaker with T-Land cutting edge style for controlled chip formation\u003c\/li\u003e\n\u003cli\u003e6 usable cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003e1\/2-inch inscribed circle and 3\/16-inch insert thickness for rigid seating in standard TNMG toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.8268 inches supports aggressive material removal\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever lock insert holding methods\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards; ISO code TNMG220404-MR4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders that accept a triangular insert with a 0.2028-inch hole diameter and support clamp, pin, or lever lock holding methods.
