Built to GNDF style in the GND series, it accepts GCML, GCMN, and GCMR inserts secured by a screw-clamp holding method. The toolholder features a maximum depth of cut of 17.78mm (0.700 inches) and a minimum groove width of 3.00mm (0.118 inches), making it well-suited for tight-tolerance face grooving applications. The shank measures 1 inch by 1 inch square and the overall length is 6 inches. The body is constructed from steel and does not include coolant-through capability.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is intended for external face grooving operations where the cutting direction is right-hand. It is used in production and job-shop turning environments on workpieces up to 11.811 inches in maximum diameter, with a maximum groove outside diameter of 300.00mm and a minimum axial groove inside diameter of 180.00mm. It is installed by machinists and CNC turning specialists on standard square-shank toolpost setups. It is a single-use toolholder style and is not configured as a multi-use tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal right-hand face grooving configuration for radial face groove applications on turning equipment\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 17.78mm (0.700 inches) for deep face groove reach\u003c\/li\u003e\n  \u003cli\u003eMinimum groove width of 3.00mm (0.118 inches) for narrow-profile grooving work\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eAccepts GCML, GCMN, and GCMR insert grades and geometries\u003c\/li\u003e\n  \u003cli\u003eSteel construction with 1 inch by 1 inch square shank and 6-inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with GCML, GCMN, and GCMR inserts at insert seat size code 3.
