The insert features a 55-degree diamond (rhombic) shape, a 0.5 inch inscribed circle, and a corner radius of 0.0156 inches (1\/64 inch). Insert length is 15.5 mm (0.611 inches), thickness is 3\/16 inch, and the FN chip breaker geometry is optimized for finishing operations. With four cutting edges and a negative rake\/negative relief (0-degree relief) configuration, this insert delivers high wear resistance across steel, stainless steel, and cast iron workpiece materials. It is installed by licensed machinists and CNC operators on indexable turning toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for general turning, facing, boring, back turning, and back boring applications. The KT315 cermet grade with PVD multilayer coating targets finishing passes on steel (P), stainless steel (M), and cast iron (K) materials where high wear resistance and consistent surface finish are the priorities. The FN chip breaker geometry manages chip formation effectively at light depths of cut, with a maximum depth of cut of 1.25 mm (0.0492 inches). The KENLOC series is a standard indexable insert platform used widely in production turning environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKT315 cermet grade with PVD multilayer TiN\/TiCN\/TiN coating for high wear resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond (DNMG) insert shape with FN finishing chip breaker geometry\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tool life per unit\u003c\/li\u003e\n  \u003cli\u003eNegative rake, 0-degree relief angle; compatible with clamp or pin insert holding methods\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 1.25 mm (0.0492 inches)  -  optimized for light finishing passes\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI (DNMG431) and ISO (DNMG150404) insert standards\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for indexable turning toolholders that accept DNMG431 (ANSI) or DNMG150404 (ISO) inserts with clamp or pin holding methods.
