It carries the NPR508 insert style designation and is manufactured to ISO code KCGX110302R15. The insert features a KC730 PVD-applied TiN coating, a parallelogram shape with a 55-degree included angle, and a negative rake geometry with a 10-degree rake angle. With four usable cutting edges and a screw-type holding method, this insert is suited for production turning where edge economy and consistent surface finish matter. Licensed HVAC and metalworking professionals will recognize this as a toolroom-grade cutting insert for precision lathe work.\u003c\/p\u003e\u003cp\u003eThis insert is engineered for profiling and turning applications on steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. The KC730 grade covers P10, P20, M10, M20, S10, and S20 material classifications, making it a versatile choice across general steel turning, interrupted cuts on stainless, and demanding superalloy or titanium work. It is installed in compatible Top Notch series screw-lock toolholders and is used in right-hand cutting orientations. Typical users include CNC machinists, tool-and-die professionals, and production turning shops requiring reliable insert performance across a range of ferrous and exotic alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for improved cost-per-edge value in production environments\u003c\/li\u003e\n\u003cli\u003eParallelogram shape with 55-degree included angle and 0-degree relief angle for profiling geometry\u003c\/li\u003e\n\u003cli\u003eNegative rake design with 10-degree rake angle and common chipbreaker for chip control\u003c\/li\u003e\n\u003cli\u003eScrew-type insert holding method for secure, repeatable seating in Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation with a 0.008-inch corner radius for controlled edge definition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series screw-lock toolholders accepting NPR508 inserts.
