Sandvik Coromant 5730536 Turning Insert DCMT32.52-MF 2015

Product Description

The SANDVIK COROMANT 5730536 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. This insert carries the DCMT32.52-MF 2015 designation and features a dual-layer TiAlN and AlCr2O3 PVD coating that provides heat resistance and extended tool life when cutting stainless steel and other demanding workpiece materials. The diamond-shaped cutting geometry measures 0.4263 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius. The MF chip breaker is engineered for light to medium finishing cuts, producing controlled chip formation at moderate feed rates. Licensed machinists and CNC operators install this insert in screw-clamped toolholders as part of the CoroTurn 107 system.

This insert is intended for finishing and semi-finishing turning operations on stainless steel workpieces, classified under ISO material group M. Its 55-degree diamond shape, neutral hand orientation, and two cutting edges make it well-suited for profiling, light contouring, and close-tolerance diameter work in both production and job-shop environments. The CoroTurn 107 series is a screw-clamped insert platform commonly used in small-to-medium bore and external turning applications where secure clamping and repeatable insert indexing are required.

Key Features

• TiAlN and AlCr2O3 dual-layer coating for heat resistance and wear performance on stainless steel
• 55-degree diamond insert shape with 7-degree relief angle for profiling and contouring clearance
• MF chip breaker geometry optimized for finishing cuts with controlled chip evacuation
• Screw-clamped holding method provides positive insert retention and repeatable seating
• Two usable cutting edges per insert for cost-effective indexing
• ISO code DCMT 11 T3 08-MF 2015 for cross-reference with international tooling standards

Compatibility

Designed for use in CoroTurn 107 series screw-clamped toolholders that accept DCMT-style inserts with a 3/8-inch inscribed circle. Confirm toolholder seat dimensions and clamping screw compatibility before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing inserts. Use the manufacturer-recommended torx or hex key torqued by hand feel to seat the clamping screw — do not over-torque, as carbide inserts are brittle and seat pockets can be damaged. Inspect the toolholder seat and chip pocket for debris before seating a new insert to ensure accurate seating and prevent premature edge chipping.
