Sandvik Coromant 5730533 Turning Insert DCMT32.52-MF 1115

Product Description

The SANDVIK COROMANT 5730533 is a solid carbide turning insert in the CoroTurn 107 series, designed for precision external and internal turning operations. This insert carries the ISO designation DCMT 11 T3 08-MF 1115 and features a 55-degree diamond shape with a neutral hand orientation. The dual-layer TiAlN and AlCr2O3 coating is applied via PVD process, delivering heat and wear resistance well suited to demanding cutting conditions. With a 1/32-inch corner radius and a 3/8-inch inscribed circle, this insert is configured for finishing and medium finishing passes. Licensed machinists and CNC operators working in production turning environments are the primary installers.

This insert is engineered primarily for turning stainless steel (ISO material group M) with secondary capability on superalloys and titanium (ISO material group S). The MF chip breaker geometry is optimized for light-to-medium depth cuts on these difficult-to-machine materials, promoting controlled chip formation and consistent surface finish. It is suited for CNC lathes and turning centers in both job shop and production settings. The screw-holding method provides positive clamping, and the 7-degree relief angle (clearance code C) reduces flank wear during continuous cuts on work-hardening alloys.

Key Features

• TiAlN and AlCr2O3 dual-layer PVD coating for high heat resistance on stainless and superalloy materials
• 55-degree diamond insert shape with 7-degree relief angle for reduced cutting forces
• MF chip breaker geometry optimized for finishing passes on stainless steel, superalloys, and titanium
• Screw-holding method (clearance code C, tolerance code M) for secure, repeatable seating
• 2 cutting edges per insert; neutral hand accommodates standard right-hand toolholders
• CoroTurn 107 series compatibility for consistent toolholder integration

Compatibility

Designed for use in CoroTurn 107 series toolholders accepting DCMT-style inserts with a screw-clamping hold method. Confirm toolholder pocket geometry matches the DCMT 11 T3 08-MF insert size code before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified feel — do not overtighten, as this can crack the carbide substrate. Inspect the toolholder pocket for chips or debris before seating the insert, and verify insert index before resuming cuts.
