This insert is designed for screw-on toolholders and features an 80-degree diamond shape with a neutral hand orientation and a positive rake angle of 5 degrees. The inscribed circle measures 7\/32 inches (0.2188 inches), the corner radius is 1\/64 inches (0.0156 inches), and the insert length is 5.65 mm. With two cutting edges and an 11-degree relief angle, the 2425779 is built for precision turning in demanding material categories. Licensed HVAC and metalworking professionals will recognize this as a high-performance insert for difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for turning stainless steel, superalloys, and titanium  -  material categories coded M and S. It is well-suited for finishing and semi-finishing operations where edge integrity and coating durability are critical. The LF chipbreaker geometry is optimized for controlled chip flow at moderate depths of cut, with a maximum depth of cut of 1.25 mm (0.0492 inches). The screw-on holding method ensures secure insert seating in compatible toolholders used in CNC turning centers and manual lathes across production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 grade with PVD TiAlN coating for high-heat and wear resistance in M and S material groups\u003c\/li\u003e\n\u003cli\u003eCPMT insert style with 80-degree diamond shape and neutral hand for versatile turning setups\u003c\/li\u003e\n\u003cli\u003eLF chipbreaker geometry promotes controlled chip evacuation during finishing cuts\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (5 degrees) reduces cutting forces on difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n\u003cli\u003eScrew-on mounting method provides rigid, repeatable insert positioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for screw-on CPMT-style toolholders conforming to ANSI and ISO standards.
