It carries the KC730 manufacturer grade with a PVD-applied TiN finish, delivering wear resistance and edge retention on a range of workpiece materials. The insert features a right-hand cutting orientation, a 3.18 mm (0.1252 inch) cutting width, and a maximum depth of cut of 6.35 mm (0.2500 inch). A positive rake angle of 10 degrees and a K-style chip breaker geometry help control chip flow and reduce cutting forces in grooving applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations on medium to hard materials classified under material grades C2, C3, and C4, which span cast iron, non-ferrous, and harder ferrous workpieces. It fits into the Top Notch series toolholding system, a common platform in production turning environments. The NFD insert style with a 55-degree included angle and a 3-degree lead angle makes it appropriate for both straight grooving and light profiling. Installation is performed by licensed machinists and CNC operators in job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with PVD TiN coating for extended tool life in grooving applications\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with a maximum depth of cut of 6.35 mm\u003c\/li\u003e\n\u003cli\u003ePositive 10-degree rake angle with K chip breaker for efficient chip control\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation; full radius designation: No; corner radius 0.19 mm (0.0075 inch)\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series for compatibility with Top Notch toolholding systems\u003c\/li\u003e\n\u003cli\u003eUNSPSC Code 23242105; insert size designation 3125\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NFD-style inserts in size 3125.
