Sandvik Coromant 5730897 Turning Insert DCMT32.52-PM 1515

Product Description

The SANDVIK COROMANT 5730897 is a DCMT-style solid carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. Part of the CoroTurn 107 series, this insert features a multilayer MTCVD-applied coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal stability across a wide range of cutting conditions. The insert carries ISO code DCMT 11 T3 08-PM 1515, a neutral hand orientation, and a PM chip breaker geometry suited for medium turning passes. The manufacturer grade 1515 is optimized for cutting ISO P workpiece materials, primarily carbon and alloy steels. Installation is performed by machining professionals in production and job-shop environments.

This insert is intended for screw-clamped toolholders compatible with DCMT-style inserts in the CoroTurn 107 platform. It is well suited for medium-duty turning of steel components in both production and repair shop settings. The PM chip breaker geometry supports moderate feed rates and depths of cut, making it a practical choice for finishing and semi-finishing passes on steel workpieces classified under ISO P material group.

Key Features

• MTCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel
• PM chip breaker geometry for controlled chip formation in medium turning
• Neutral hand insert orientation for flexible toolholder pairing
• Screw-clamped insert holding method for secure, repeatable seating
• Maximum depth of cut of 0.4263 inches supports semi-finishing and finishing passes
• Full radius insert geometry available; ISO P primary workpiece material classification

Compatibility

Designed for use with DCMT-style screw-clamped toolholders in the SANDVIK COROMANT CoroTurn 107 turning system. Compatible toolholders must accept a DCMT insert with a 3/8-inch inscribed circle and a 5/32-inch insert thickness. Verify toolholder designation against the CoroTurn 107 catalog to confirm proper seating and clamping.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the machine spindle stopped and all axis motion disabled per shop lockout-tagout procedures. Use the correct Torx or hex key at the manufacturer-specified clamping torque range for CoroTurn 107 screw-lock seats — consult the toolholder documentation for the applicable fastener spec. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Do not use a damaged or deformed clamping screw, as improper seating increases the risk of insert breakage during cutting.
