Built on a 1 x 1 inch square shank with a 6-inch overall length, it accepts RN..43. series round inserts held by a clamp and screw method. The -5 degree negative rake angle and 15-degree lead angle position the insert for stable, controlled cuts on steel and other ferrous materials. Toolholder body is constructed from steel for rigidity under heavy turning loads. This holder is installed by machinists and CNC operators in production and job-shop turning applications.\u003c\/p\u003e\n\u003cp\u003eThe HERTEL 1000123 is suited for external turning operations on manual engine lathes and CNC turning centers. The right-hand orientation means it feeds from right to left along the workpiece. Its 1-inch square shank fits standard tool blocks and turret stations commonly found in general-purpose turning setups. The 1.25-inch back-of-bar to cutting edge dimension and 0.5-inch insert inscribed circle support consistent tool height setup in production environments. No coolant-through capability is present, so external coolant delivery is required when running coolant-assisted cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMRGN toolholder style with right-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eNegative rake at -5 degrees with 15-degree lead angle for stable insert engagement\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert retention for secure indexing of RN..43. round inserts\u003c\/li\u003e\n  \u003cli\u003e1 x 1 inch square shank fits standard turret and tool block stations\u003c\/li\u003e\n  \u003cli\u003eSteel toolholder body provides rigidity under turning loads\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length with 1.25-inch back-of-bar to cutting edge dimension\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept RN..43. series round indexable inserts with a 0.5-inch inscribed circle.
