Sandvik Coromant 5731630 Turning Toolholder DCLNR204D Cnmg 432

Product Description

The SANDVIK COROMANT 5731630 is a right-hand indexable turning toolholder in the DCLNR204D style, designed for use with CNMG 432 inserts secured by a wedge clamping method. Built from steel with a 1.25 x 1.25 inch square shank and an overall length of 6 inches, this toolholder delivers a rigid, repeatable platform for external turning and facing operations on CNC lathes and turning centers. The negative rake geometry at -6 degrees suits heavy interrupted and continuous cuts in a wide range of workpiece materials. Machinists and toolroom professionals in production and job-shop environments rely on this holder for consistent insert seating and secure clamping during high-feed operations.

This toolholder is suited for facing and external turning applications on CNC lathes in both production and job-shop settings. The DCLNR style positions the insert at a lead angle appropriate for straight turning and facing passes. With a head length of 1.26 inches and a back-of-bar to cutting edge distance of 6 inches, the holder fits standard tool turret pockets sized for a 1.25 x 1.25 inch shank. It accepts CNMG 432 inserts with a 0.5 inch inscribed circle, a widely stocked insert geometry available in numerous grades for steel, cast iron, and stainless applications.
