It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a range of cutting conditions. The insert has a 0.5 inch (12.70 mm) inscribed circle, a 0.0469 inch (1.19 mm) corner radius, and a neutral hand orientation. It is suited for machining cast iron (ISO K) and steel (ISO P) workpiece materials and is commonly specified by machinists and CNC operators in job shops and production environments.\u003c\/p\u003e\u003cp\u003eThis insert is applied in medium to finishing turning operations where consistent edge performance and tool life are priorities. The QM chip breaker geometry is suited for stable chip control across varying depths of cut and feed rates. The 4415 grade is a CVD-coated carbide grade optimized for ISO K and ISO P materials, making this insert a practical choice for shops running mixed-material turning programs on both manual and automated turning equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n\u003cli\u003eSNMG square insert shape with 0 degree relief angle (clearance code N, tolerance code M)\u003c\/li\u003e\n\u003cli\u003e0.5 inch (12.70 mm) inscribed circle for consistent engagement geometry\u003c\/li\u003e\n\u003cli\u003e1.19 mm (0.0469 inch) corner radius for controlled surface finish\u003c\/li\u003e\n\u003cli\u003eQM chip breaker geometry for effective chip control in medium turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation — compatible with both left- and right-hand toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for SNMG 12 04 12 format toolholders using clamp or screw insert-holding methods, consistent with T-Max P series tooling systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTurning inserts of this type are installed and replaced by machinists or CNC tooling technicians.
