Sandvik Coromant 5730800 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5730800 is a right-hand indexable turning toolholder in the DCLN style, designed to seat and secure CNMG 12 04 08 inserts using a wedge clamping method. Part of the T-Max P series, this toolholder features a square 0.625 inch by 0.625 inch shank, an overall length of 4.0 inches, and a negative rake angle of -6 degrees. It is constructed from steel for rigidity under continuous turning loads. This toolholder is installed by machinists and CNC turning specialists performing external turning operations on metal workpieces.

The 5730800 is suited for external turning applications on CNC lathes and manual turning centers in both production shop and job shop environments. The DCLN configuration positions the insert at a lead angle that supports straight turning and facing passes. The wedge clamping system provides secure insert retention during interrupted and continuous cuts. This is a single-use configuration toolholder with no multi-use capability, intended for dedicated turning setups where consistent insert positioning and repeatability are required.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the machine placed in an energy-isolated state before any tooling change. Use the appropriate Torx or hex key to secure the wedge clamp to the manufacturer-specified seating condition — do not over-torque the clamp screw, as this can distort the insert pocket. Verify insert seating and tool overhang before resuming cutting operations.
