It carries a K68 grade designation and is supplied in an uncoated (bright) finish, making it suited for cutting non-ferrous metals, cast iron, and abrasive materials where coating adhesion is a concern. The insert features a left-hand orientation, a 0.189-inch (4.80 mm) cutting width, and a maximum depth of cut of 0.250 inch (6.35 mm). A 0.0225-inch (0.57 mm) corner radius and a neutral rake geometry contribute to consistent chip formation and edge stability during grooving passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in turning applications where precise groove width and depth control are required. The NG-style insert seats into a size-4 Top Notch toolholder. With a C3 material grade classification and a 55-degree included angle, it is well matched to finishing and semi-finishing grooving cuts in production environments. Machinists and CNC operators working in job shops or production turning cells will find it appropriate for groove widths in the 0.189-inch range with depths falling within the 0.200- to 0.300-inch range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide K68 grade, uncoated (bright) finish for abrasive and non-ferrous material applications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for right-to-left grooving cuts\u003c\/li\u003e\n  \u003cli\u003e0.189-inch (4.80 mm) cutting width with a maximum depth of cut of 0.250 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e0.0225-inch (0.57 mm) corner radius with neutral rake geometry\u003c\/li\u003e\n  \u003cli\u003eNG4189 insert style, size-4 seat, Top Notch series toolholder compatible\u003c\/li\u003e\n  \u003cli\u003e55-degree included angle for defined groove geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series, size-4 insert seat toolholders that accept the NG-style insert geometry.
