Built in the NVR toolholder style, it accepts 2IR series inserts secured by a screw-holding method for positive insert registration and repeatable thread form accuracy. The shank diameter is 3\/8 inch with a decimal shank height of 0.355 inches and an overall length of 2.953 inches. Weighing 0.482 pounds, this toolholder is a compact, no-coolant unit suited for machinists and toolroom technicians running internal threading passes on bores and threaded features.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is used for cutting internal threads in bore applications across job shop, production, and maintenance turning operations. The right-hand configuration is suited for standard lathe setups where the tool feeds from right to left along the workpiece. The 1\/4 inch insert inscribed circle and 2IR insert compatibility make it appropriate for threading smaller internal diameters where clearance is a factor. It is a single-purpose threading tool and is not rated as a multi-use holder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNVR toolholder style for internal threading applications\u003c\/li\u003e\n  \u003cli\u003eAccepts 2IR series indexable inserts with 1\/4 inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eScrew insert holding method for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard lathe setups\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter with 2.953 inch overall length\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design; operates without internal coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 2IR series indexable threading inserts with a 1\/4 inch inscribed circle.
