Sandvik Coromant 5730591 Turning Toolholder Dclnl Wedge

Product Description

The SANDVIK COROMANT 5730591 is a left-hand indexable turning toolholder designed for external turning and facing operations on CNC lathes and turning centers. It uses a wedge clamping method to secure CNMG 432 inserts and features a negative rake geometry with a rake angle of -6 degrees, which promotes strong insert support and is well-suited for interrupted cuts and harder workpiece materials. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. The body is constructed from steel for rigidity under continuous cutting loads. This toolholder is installed by machinists and CNC toolroom technicians in production and job-shop environments.

This toolholder is built for facing applications where a left-hand cutting orientation is required. The DCLNL style seats the insert at a lead angle suited to facing passes and light to medium turning operations. With a head length of 1.26 inches and a back-of-bar to cutting edge distance of 4.5 inches, it fits standard OD turning setups on most toolpost and turret configurations. The insert inscribed circle measures 0.5 inches, confirming compatibility with the CNMG 432 insert family. The multi-use designation allows it to serve across a range of turning operations beyond its primary facing application.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before mounting or changing the toolholder. Verify the turret or toolpost bore and bolt pattern matches the shank dimensions before installation. Confirm insert seating and wedge clamp torque per machine tool manufacturer guidelines before initiating a cut.
