Sandvik Coromant 5732477 DVTNR163D Turning Toolholder

Product Description

The SANDVIK COROMANT 5732477 is a right-hand indexable turning toolholder in the DVTNR style, designed to hold VNMG 332 inserts using a wedge clamping method. It features a 1 inch by 1 inch square shank and an overall length of 6 inches, making it a standard-size toolholder suited for CNC and manual lathe turning operations. The negative rake geometry at -4 degrees supports stable, controlled cutting, particularly in facing applications. Steel construction provides rigidity under interrupted and continuous cut conditions. Licensed machinists and CNC setup technicians are the primary installers and users of this toolholder.

This toolholder is intended for external turning and facing operations on CNC lathes and manual engine lathes. The DVTNR configuration positions the insert for right-hand cutting with a lead angle suited to facing and longitudinal passes. The wedge clamping method locks the insert firmly, reducing movement during high-feed or heavy-depth cuts. With a head length of 1.54 inches and a back-of-bar to cutting edge measurement of 6 inches, the toolholder fits standard tool blocks and quick-change turrets that accept 1 inch shank tooling.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the machine spindle before changing or indexing inserts.

Ensure the shank is fully seated and clamped in the tool block before resuming cuts.
