It features an 80-degree diamond shape, a neutral hand orientation, and a negative rake geometry with a chamfered and honed cutting edge. The insert measures 12.9 mm (0.5077 inches) in length with a 1\/2-inch inscribed circle and a 1\/32-inch corner radius. Four cutting edges are available per insert. Licensed HVAC techs and machinists in production turning environments select this insert for its durability on steel and cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel and cast iron. It is a fit for medium to roughing passes where a negative rake geometry provides edge strength. The RP chip breaker geometry helps manage chip control across a range of feed rates and depths. Maximum depth of cut is 1.25 mm (0.0492 inches). It is held in place using a clamp and pin method, consistent with standard CNMG toolholders meeting ANSI and ISO standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCP05 grade with multilayer CVD TiCN and Al2O3 coating for wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG style) with negative rake and 5-degree rake angle\u003c\/li\u003e\n\u003cli\u003eRP chip breaker geometry for effective chip control during turning, facing, and boring\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert for cost efficiency\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for improved edge integrity\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method compatible with standard CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in ANSI- and ISO-standard CNMG toolholders using clamp and pin insert retention.
