Sandvik Coromant 5731062 DDJNR164C Turning Toolholder

Product Description

The SANDVIK COROMANT 5731062 is a right-hand indexable turning toolholder in the DDJNR style, designed for use with DNMG 432 inserts secured by a wedge clamping method. The toolholder features a 1 x 1 inch square shank and an overall length of 5 inches, making it a compact and rigid solution for facing operations on CNC lathes and turning centers. The negative rake geometry at -6 degrees is suited for interrupted cuts and harder workpiece materials. At 1.43 pounds, it is machined from steel for durability under continuous cutting loads. Licensed machinists and CNC operators install this toolholder in production and job-shop turning applications.

This toolholder is intended for external turning and facing operations where precise, repeatable insert positioning is required. The wedge clamping system locks the DNMG 432 insert firmly, reducing insert movement during heavy radial or axial cuts. The 1.5500-inch head length and 0.5000-inch insert inscribed circle support stable depth-of-cut control in both roughing and semi-finishing passes. It is a multi-use tool, adaptable to a range of facing and profiling cuts on standard CNC lathes equipped with a 1-inch square tool block or gang-style turret.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Confirm the machine is powered down and the spindle is fully stopped before mounting or removing the toolholder. Seat the shank fully in the turret or tool block and torque all clamping fasteners according to the machine manufacturer specifications. When indexing or replacing inserts, use the appropriate torx or hex key specified for the wedge clamp and inspect the insert pocket for debris before reseating.
