It carries an ANSI insert code of TNMG432 and an ISO code of TNMG220408-MR4. The insert features a 60-degree triangular shape with a 0.5-inch inscribed circle, a 1\/32-inch corner radius (0.0315 inches), and a negative rake, negative side clearance geometry. The MR4 chip breaker is optimized for roughing and medium machining passes. With six cutting edges per insert, this grade 883 carbide offers high wear resistance combined with toughness for S-grade workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for CNC turning centers and manual lathes where the workpiece material is a superalloy or titanium (primary material code S), with secondary suitability for steel (M), cast iron (K), non-ferrous metals (N), and hardened materials (H). Typical applications include back turning, boring, facing, and standard OD turning. The insert is held via clamp, pin, or lever-lock toolholders accepting TNMG-format seats. It is intended for use by machinists and tooling specialists in aerospace, power generation, and precision manufacturing environments where material toughness and thermal resistance are primary concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 883 solid carbide with uncoated (bright) finish for superalloy and titanium machining\u003c\/li\u003e\n\u003cli\u003eMR4 chip breaker geometry rated for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape provides six usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eNegative rake and negative side clearance (clearance code N, tolerance code M) for rigid, stable cutting\u003c\/li\u003e\n\u003cli\u003eT-Land cutting edge style improves edge strength on hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFits TNMG-format toolholders designed for ANSI size code 432 inserts.
