Sandvik Coromant 5731634 Turning Toolholder DCLNR205D Wedge

Product Description

The SANDVIK COROMANT 5731634 is a right-hand indexable turning toolholder in the DCLNR style, designed to accept CNMG 543 inserts secured by a wedge clamping method. The shank measures 1.25 x 1.25 inches with an overall length of 6.0 inches and a head length of 1.54 inches. Built from steel with a negative rake angle of -6 degrees, this toolholder delivers stable, rigid insert seating for facing and turning operations on CNC lathes and manual turning centers. It is installed by machinists and toolroom technicians in production and job-shop environments.

This toolholder is suited for facing operations on ferrous and non-ferrous workpieces in both production and job-shop turning setups. The DCLNR style positions the insert at a negative rake, making it a practical choice for interrupted cuts and general-purpose external turning where cutting-edge rigidity is a priority. The wedge clamping system provides positive insert retention during high-feed and heavy-depth-of-cut passes. It accommodates CNMG 543 inserts, which are widely used for medium to rough turning across a broad range of materials.
