The triangular insert geometry features a 60-degree included angle, a 0.5-inch inscribed circle, a 0.0315-inch corner radius, and a negative rake with T-Land cutting edge style. Six usable cutting edges are available per insert. The MR4 chip breaker geometry supports controlled chip formation across a range of depths of cut up to 0.7874 inches. Licensed machinists and CNC operators install this insert in compatible turning tool holders for production and job-shop metalcutting applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for machining superalloys and titanium (ISO material group S), with secondary suitability for steel, stainless steel, and cast iron (ISO groups P, M, and K). Typical applications include external turning, facing, boring, and back turning operations on CNC lathes and turning centers. The neutral hand orientation makes it suitable for both left- and right-hand tool holder setups. The insert is held by clamp, pin, or lever-lock style holders compatible with the TNMG insert seat standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTS2500 carbide grade with multilayer PVD TiAlN and TiN coating for heat and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eMR4 chip breaker designed for controlled chip formation in superalloy and titanium cutting\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges per insert maximize tool utilization and reduce per-edge cost\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style provides edge reinforcement for interrupted and demanding cuts\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with left- and right-hand TNMG tool holders\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO insert standards; ISO code TNMG220408-MR4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMG-style insert seats accepting clamp, pin, or lever-lock holding methods.
