Sandvik Coromant 5731058 DDJNR163D Turning Toolholder

Product Description

The SANDVIK COROMANT 5731058 is a right-hand indexable turning toolholder in the DDJNR163D style, designed for external turning and facing operations on CNC lathes and turning centers. It accepts DNMG 332 inserts and uses a wedge clamping method to lock the insert firmly during interrupted and continuous cuts. The 1 inch by 1 inch square shank provides rigid setup in standard tool blocks. The negative rake geometry at -6 degrees is well suited for harder workpiece materials and heavy cuts where edge strength is critical. Weighing 1.66 pounds, this steel-body toolholder is built for production environments where repeatable setup and reliable insert seating matter most.

This toolholder is intended for use in metal-cutting applications where facing and turning operations are performed on a lathe or turning center. The DDJNR style positions the insert for right-hand cutting with a negative rake angle, making it appropriate for general-purpose turning of steel, cast iron, and similar materials. The 6 inch overall length and 1.1900 inch head length suit standard toolpost configurations. It is a multi-use tool, meaning the same holder body can be reloaded with fresh DNMG 332 inserts as edges wear, reducing tooling cost per part over time. Machinists and CNC operators in job shops and production facilities are the primary users.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down the machine and engage the spindle lock before seating or indexing any insert. Use the appropriate torx or hex key to tighten the wedge clamp screw to snug without over-torquing the insert pocket. Verify insert seating and shim condition before resuming cuts, and confirm tool offset values in the control after any holder change.
