Part of the CoroThread 266 series, it accepts 266RG to 22 inserts secured by a screw-clamping method. The right-hand toolholder features a 1.25 inch round shank with a 30 mm (1.181 inch) shank height and a 14 inch overall length. Built from steel, it includes coolant-through capability to aid chip evacuation and extend insert life during threading passes. This toolholder suits machinists and CNC operators working in production or job-shop turning environments.\u003c\/p\u003e\u003cp\u003eThe 5758099 is suited for threading applications on lathes where both internal and external profiles are required from a single toolholder setup. The minimum bore diameter of 1.58 inches defines the smallest bore it can reach for internal threading work. A head length of 3.75 inches and a center-to-cutting-edge distance of 22 mm (0.866 inch) provide the reach and geometry needed for consistent thread profiles. It is typically installed by CNC machinists, tool-and-die professionals, and precision turning specialists working with ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHandles both internal and external threading from a single right-hand toolholder\u003c\/li\u003e\n\u003cli\u003eCompatible with 266RG to 22 indexable inserts using screw-type insert holding\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip control and thermal management during threading\u003c\/li\u003e\n\u003cli\u003eSteel construction provides rigidity for consistent thread form accuracy\u003c\/li\u003e\n\u003cli\u003e14 inch overall length with a 3.75 inch head length for extended reach applications\u003c\/li\u003e\n\u003cli\u003ePart of the CoroThread 266 series for broad insert availability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 266RG to 22 series indexable threading inserts.
