Sandvik Coromant 5758105 Threading Toolholder 1.5 in Shank

Product Description

The SANDVIK COROMANT 5758105 is a steel indexable threading toolholder designed for both internal and external thread cutting operations on CNC lathes and turning centers. Built to the CoroThread 266 series standard, this right-hand toolholder accepts 266RL to 22 inserts secured by a screw-clamping method. It features a 1.5-inch shank diameter, a minimum bore diameter of 1.97 inches, and coolant-through capability for improved chip evacuation and tool life during high-volume threading applications. The overall length is 15 inches, making it suited for deep-reach setups where extended bar length is required.

This toolholder is intended for use in industrial machining environments where precision threading is performed on lathes, turning centers, or mill-turn machines. Its dual internal and external threading capability reduces the need for multiple holders in a single setup. The 4.5-inch head length and 27 mm center-to-cutting-edge offset support stable cutting geometry in both through-bore and face-thread applications. It is typically installed and serviced by machinists and CNC setup technicians working in precision manufacturing and job shop environments.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Before mounting, confirm the machine spindle and turret are fully stopped and all motion is locked out per facility lockout/tagout procedures. Ensure the toolholder shank seats fully and evenly in the turret block before tightening clamping bolts. Verify coolant-through passages are clear and connected before returning the machine to operation.
