Manufactured in grade K68 with a bright uncoated finish, this insert delivers consistent performance in non-ferrous materials, cast iron, and hardened workpieces where coating is not required. The insert features a 4.8 mm cutting width (0.189 inches) and a maximum depth of cut of 6.35 mm (0.250 inches). The neutral rake geometry and 55-degree included angle contribute to stable chip formation during grooving passes. Installation and tooling selection are handled by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert fits Top Notch series toolholders and is suited for precision grooving applications in both production and repair turning operations. With a right-hand cutting orientation and NG-style insert geometry, it is typically applied in OD grooving on ferrous and non-ferrous materials where a controlled groove width and depth are critical. The 3-degree lead angle and 0.57 mm corner radius support accurate groove profiling without full-radius geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K68 grade with bright uncoated finish for use in non-ferrous and cast iron applications\u003c\/li\u003e\n  \u003cli\u003e4.8 mm cutting width (0.189 inches) for precise groove dimensioning\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 6.35 mm (0.250 inches) within a range of 5.00 mm to 10.00 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation with neutral rake geometry\u003c\/li\u003e\n  \u003cli\u003e0.57 mm corner radius and 3-degree lead angle for controlled groove profile\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility for secure, repeatable insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NG-style inserts with insert seat size 4.
