Manufactured in grade K68 with a bright, uncoated finish, this insert delivers consistent cutting performance in non-ferrous metals, cast iron, and abrasive workpiece materials where coating is not required. The right-hand orientation, neutral rake geometry, and 3.96 mm cutting width make it a reliable choice for precision groove profiles. Installation is straightforward for qualified machinists and toolroom technicians working with compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production and job-shop turning environments where groove width accuracy and depth control are critical. The 3.96 mm cutting width and a maximum depth of cut of 3.81 mm support groove profiles in a range of workpiece diameters. The 0.19 mm corner radius reduces stress concentration at the groove base without introducing excessive burr. It is appropriate for both residential machine shops and industrial manufacturing cells requiring repeatable, high-quality groove geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in manufacturer grade K68, material grade C3, suited for non-ferrous and abrasive materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for direct cutting performance without coating-induced dimensional offset\u003c\/li\u003e\n\u003cli\u003e3.96 mm cutting width with a 3.81 mm maximum depth of cut for controlled groove profiles\u003c\/li\u003e\n\u003cli\u003e0.19 mm corner radius reduces stress at groove root while maintaining profile accuracy\u003c\/li\u003e\n\u003cli\u003eNeutral rake geometry and right-hand orientation for stable, consistent chip formation\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series for use with compatible Top Notch grooving toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series grooving toolholders that accept NG-style inserts.
