Sandvik Coromant 5731372 Turning Insert Dcmx Coroturn 107

Product Description

The SANDVIK COROMANT 5731372 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes. Cataloged under the CoroTurn 107 series and carrying the ISO designation DCMX11T304WM2015, this insert features a 55-degree diamond shape (D) with a neutral hand orientation. The multilayer MTCVD coating stack — TiCN, Al2O3, and TiN — provides wear resistance and thermal stability suited for stainless steel and other ISO M-group workpiece materials. The WM chip breaker geometry controls chip evacuation at moderate feeds and depths. Two cutting edges are available per insert, and the screw-lock holding method keeps the insert securely seated under interrupted or continuous cuts.

This insert is intended for light-to-medium turning of stainless steel and similar ISO M-group materials on CNC turning centers and live-tooling lathes. The wiper edge geometry produces improved surface finish at standard feed rates without requiring a feed reduction. The 0.4421-inch maximum depth of cut and 3/8-inch inscribed circle make this insert appropriate for small-to-mid bore and OD profiling work. It is installed and changed by machinists, CNC operators, and toolroom technicians in precision manufacturing and job-shop environments.

Key Features

• 55-degree diamond insert shape (D) provides a smaller nose angle for profiling and contour turning
• MTCVD multilayer coating (TiCN, Al2O3, TiN) delivers wear resistance on stainless steel and ISO M materials
• Wiper edge geometry improves surface finish at conventional feed rates
• Screw-lock holding method (hole diameter 0.1732 inches) ensures repeatable seating in CoroTurn 107 toolholders
• Neutral hand orientation suits both right-hand and left-hand tool setups depending on holder selection
• Two cutting edges per insert reduce per-edge tooling cost

Compatibility

Designed for use in SANDVIK COROMANT CoroTurn 107 series toolholders accepting DCMX insert geometry with a screw-lock holding method. ISO code DCMX11T304WM2015 identifies compatible holder pockets directly.

Installation Notes

Insert changes are performed by a machinist or CNC operator with the machine in a full stop and all axes at a safe home position. Use the appropriate Torx or hex key torque driver specified by the toolholder manufacturer when seating the clamping screw — do not overtighten. Inspect the insert seat and chip pocket for debris before seating a fresh insert. Always verify runout and tool offset after an insert change before returning the program to full feed and speed.
