It carries the TP2501 manufacturer grade and features a Duratomic CVD multilayer coating of TiCN, Al2O3, and Cr for extended tool life under demanding cutting conditions. The triangular insert body provides six cutting edges and a 3\/4 inch inscribed circle, while the MR7 chip breaker geometry with a T-Land cutting edge style controls chip flow across a broad range of feed and depth conditions. Corner radius measures 0.0945 inches (3\/32 inch nominal). This insert is installed by CNC machinists and turning center operators working in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 02960779 is suited for back turning, boring, facing, and general turning applications. Its primary target workpiece material is steel, with secondary suitability for stainless steel and cast iron. The MR7 chip breaker geometry and Duratomic coating make it effective across roughing to semi-finishing passes in those material families. Material grades P10, P20, P30, and P35 are covered. Maximum depth of cut reaches 1.0669 inches, supporting a wide range of material removal scenarios from light finishing to aggressive roughing on qualifying setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDuratomic CVD coating: TiCN, Al2O3, and Cr multilayer for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eSix cutting edges on a 60-degree triangle body for cost efficiency per insert\u003c\/li\u003e\n\u003cli\u003eMR7 chip breaker with T-Land edge style for chip control across steel and stainless applications\u003c\/li\u003e\n\u003cli\u003eNegative rake, neutral hand geometry compatible with clamp, pin, and lever lock holding systems\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.0669 inches supports roughing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO standards; ISO code TNMG330924-MR7\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders that accept clamp, pin, or lever lock insert retention.
