Sandvik Coromant 5732200 Turning Insert Dpmt Coroturn 111

Product Description

The SANDVIK COROMANT 5732200 is a DPMT-style turning insert from the CoroTurn 111 series, manufactured in solid carbide with a PVD-applied TiCN and TiN multilayer coating. The insert features a 55-degree diamond shape, a neutral hand orientation, and a precision-ground PM chip breaker geometry. With an inscribed circle of 0.375 inches and a corner radius of 0.0156 inches, it is suited to finish and semi-finish turning operations requiring tight tolerances. The clearance code is P and the tolerance code is M, placing it in the DPMT classification. Cutting professionals working with steel, stainless steel, and cast iron select this insert for its coating durability and controlled chip evacuation under continuous cutting conditions.

This insert is designed for screw-held toolholders compatible with the CoroTurn 111 system. Primary workpiece material is steel (ISO material group P), with secondary suitability for stainless steel (group M) and cast iron (group K). Typical applications include external turning, facing, and light profiling on CNC lathes in production and job-shop environments. The two cutting edges per insert contribute to cost-per-edge efficiency in high-cycle operations. Licensed machinists and CNC operators working to tight dimensional tolerances on ferrous materials will find this geometry appropriate for low-to-moderate feed-rate passes.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before changing inserts, confirm the machine is in a full stop condition with the spindle locked and all axes at a safe position. Use the manufacturer-specified torx or hex key for the clamping screw to avoid damaging the seating pocket; do not over-torque the screw. Inspect the toolholder pocket and screw threads for chips or wear before seating the new insert.
