It carries the TS2500 manufacturer grade and features a multilayer PVD coating of TiAlN and TiN, which supports elevated cutting speeds and extended tool life when machining difficult materials. The insert has a 60-degree triangular shape with a neutral hand orientation and a 0.0315-inch corner radius. With 6 usable cutting edges and a maximum depth of cut of 0.5709 inches, it delivers consistent performance in production environments where insert efficiency and cost-per-edge matter.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning, facing, boring, and back turning applications. Its primary workpiece material designation is superalloys and titanium (ISO code S), making it well suited for aerospace, defense, and high-temperature alloy machining. Secondary materials include steel, stainless steel, and cast iron (ISO codes P, M, and K). The MR4 chip breaker geometry and T-Land cutting edge style help manage chip formation and reduce built-up edge when working with these demanding materials. It is applicable to production shops running high-mix or high-volume lathe work across these material families.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTS2500 grade with multilayer PVD TiAlN and TiN coating for extended tool life in 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 cutting edges per insert for a low cost-per-edge in production use\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard TNMG toolholders using clamp, pin, or lever lock holding methods\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.5709 inches supports a wide range of roughing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; ISO designation TNMG160408-MR4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders that accept a 3\/8-inch inscribed circle triangular insert with clamp, pin, or lever lock holding methods.
