It features a negative 4-degree rake angle and a 93-degree lead angle, making it well suited for roughing and finishing passes where cutting forces need to be managed through neutral-to-negative geometry. The shank measures 1 inch wide by 1 inch tall with an overall length of 6 inches. This toolholder accepts VNMG 432 inserts secured by a top clamp, a reliable holding method for maintaining insert position under heavy cuts.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is used in turning applications across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, and high-temperature alloys, reflected by its universal primary workpiece material classification. It is a practical choice for job shops and production environments running right-hand cutting operations. The 1-inch-square shank fits standard tool blocks and turret positions sized for that cross-section. Coolant-through capability is not included, so external coolant delivery is required when flood or mist cooling is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMVJN toolholder style with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eNegative 4-degree rake angle with 93-degree lead angle for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eAccepts VNMG 432 inserts via top-clamp holding method\u003c\/li\u003e\n  \u003cli\u003e1-inch x 1-inch shank cross-section, 6-inch overall length\u003c\/li\u003e\n  \u003cli\u003eHead length of 2 inches; back of bar to cutting edge measures 1.25 inches\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material compatibility covering material codes H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept VNMG 432 inserts with a compatible insert size code of VN43 and an insert inscribed circle of 0.5 inch.
