Sandvik Coromant 5730576 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5730576 is a left-hand indexable turning toolholder in the DCLNR style, designed to accept CNMG 543 inserts secured by a wedge clamping system. Built from steel with a 1 x 1 inch square shank and an overall length of 6 inches, this toolholder delivers a rigid, repeatable setup for facing operations on CNC lathes and turning centers. The negative rake geometry at -6 degrees suits interrupted cuts and harder workpiece materials. At 1.83 pounds, it is a compact yet robust holder suited for production turning environments where consistent insert indexing and tool life matter.

This toolholder is intended for external turning and facing applications on manual lathes, CNC turning centers, and multi-axis turning equipment in both job shop and production settings. The wedge clamping method provides strong insert retention and rapid indexing, reducing changeover time during high-cycle runs. It is appropriate for machinists and tooling specialists working with ferrous and non-ferrous materials where CNMG 543 insert geometry is preferred. The DCLNL165D designation indicates a left-hand cutting direction suitable for specific approach angles and tool path strategies.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with lathe toolholder setup procedures. Ensure the machine spindle is fully stopped and all motion is locked out before mounting or adjusting the toolholder. Secure the shank in the turret or tool post to the required clamping depth using manufacturer torque specifications for the specific machine. Inspect the insert seat and clamping wedge for debris or wear before seating a new insert.
