Sandvik Coromant 5758097 Threading Toolholder Right Hand

Product Description

The SANDVIK COROMANT 5758097 is a right-hand indexable threading toolholder designed for both internal and external thread cutting operations. Part of the CoroThread 266 series, it accepts 266RL to 16 inserts secured by a screw-holding method. The steel shank measures 1.1810 inches in height (30 mm) and 1.25 inches in diameter, with a 14-inch overall length. A minimum bore diameter of 1.58 inches makes it suitable for a range of internal threading applications. Built-in coolant-through capability supports heat management and chip evacuation during continuous threading cuts. Licensed machinists and CNC lathe operators will find this toolholder appropriate for production threading work requiring consistent insert indexing.

The 5758097 is used in CNC turning centers and manual lathes for threading operations on ferrous and non-ferrous workpieces. The right-hand orientation suits standard spindle rotation configurations. With a head length of 3.75 inches and a center-to-cutting-edge dimension of 0.866 inches (22 mm), the holder provides the reach and positioning geometry needed for precise thread form control. The 3/8-inch insert inscribed circle (IC) size is compatible with standard 266RL to 16 series inserts. Both job shop and production environments are typical deployment settings.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before mounting or removing the toolholder. Secure the shank in the tool block to the appropriate clamping torque per the machine tool builder specification. Verify insert seating and screw torque before resuming cutting operations, and confirm coolant-through supply lines are connected if the feature is being used.
