Manufactured to the NR2031 style in the Top Notch series, this left-hand insert features a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and extended tool life. It delivers a cutting width of 1.58 mm (0.0622 inch) and a maximum depth of cut of 2.79 mm (0.1098 inch). The full-radius geometry with a 0.79 mm corner radius and neutral rake angle supports stable chip control during grooving and profiling. Machining professionals and toolroom technicians select this insert for its KC850 grade performance in steel and cast iron applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for metric-dimensioned grooving applications on lathes running ferrous materials. The KC850 grade with CVD multilayer coating targets material grades C5 and C6, making it appropriate for steel turning and finishing passes where consistent groove geometry is required. It is a single-use, non-multi-purpose insert and is sold in minimum order quantities of 5 units, with individual package quantities of 1. The Top Notch series tooling system it belongs to is a widely used platform in production turning environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNR2031 left-hand insert style in the established Top Notch series tooling platform\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003e1.58 mm cutting width (0.0622 inch) with full radius and 0.79 mm corner radius\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 2.79 mm (0.1098 inch), within a range of 2.00 to 3.00 mm\u003c\/li\u003e\n\u003cli\u003eNeutral rake geometry for stable chip formation in grooving and turn-groove applications\u003c\/li\u003e\n\u003cli\u003eKC850 grade rated for C5 and C6 material groups including steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for Top Notch series grooving toolholders and systems that accept the NR2031 insert size.
