It features an 80-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and an 11-degree relief angle. The inscribed circle measures 0.375 inches, insert length is 0.3808 inches, and insert thickness is 0.1563 inches. The corner radius is 0.0156 inches (1\/64 inch). With two cutting edges and a honed cutting edge style, this insert is engineered for high wear resistance across steel, stainless steel, cast iron, and superalloy workpiece materials. It is installed via screw-on holding method and carries a neutral hand designation.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium machining operations including turning, facing, and boring on CNC lathes and turning centers in both production and job-shop environments. It performs across a range of primary workpiece materials including steel (P), stainless steel (M), cast iron (K), aluminum (N), superalloys and titanium (S), and hardened materials (H). The chip breaker is a common medium-machining geometry. Maximum depth of cut is 0.1268 inches. This insert targets applications where consistent surface finish and tool life are priorities across multi-material production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePVD TiAlN coating for high wear resistance in steel, stainless steel, and superalloy applications\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eKCU10 grade with 11-degree relief angle and honed cutting edge style\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert for extended usable tool life\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method compatible with CPGM-style toolholders\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring in a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for CPGM-style screw-on toolholders.
