This left-hand insert carries the NR3062 style designation and is manufactured to the KC730 grade, a PVD-coated carbide with a TiN finish engineered for improved wear resistance and tool life in turning applications. The cutting width is 3.18 mm (0.1252 inches) with a maximum depth of cut of 3.81 mm (0.1500 inches). The full-radius geometry and neutral rake provide controlled chip formation across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external grooving, undercutting, and groove-turning operations on ferrous and non-ferrous materials classified under material grades C2, C3, and C4. The 55-degree included angle and 1.59 mm (0.0626 inch) corner radius make it appropriate for finish and semi-finish grooving passes in moderate to high-volume production environments. It is installed by machinists and CNC turning specialists in job shop and production machine shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 PVD-coated solid carbide grade with TiN finish for extended wear life\u003c\/li\u003e\n  \u003cli\u003e3.18 mm cutting width for consistent groove sizing\u003c\/li\u003e\n  \u003cli\u003eFull radius geometry with 1.59 mm corner radius for smooth groove floor finish\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for dedicated left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eNeutral rake angle supports stable cutting across C2, C3, and C4 material grades\u003c\/li\u003e\n  \u003cli\u003eNR style, Top Notch series for positive indexing and secure clamping in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders that accept NR-style grooving inserts with the 3062 insert size designation.
