Sandvik Coromant 5731122 Turning Insert DNMG433-QM H13A

Product Description

The SANDVIK COROMANT 5731122 is a solid carbide turning insert in the DNMG433-QM H13A designation, part of the T-Max P series. It features a 55-degree diamond shape (DNMG insert style) with a neutral hand orientation and an uncoated bright finish. The inscribed circle measures 0.5 inches, the insert length is 0.5632 inches, and the corner radius is 0.0469 inches (3/64 inches). With four cutting edges and a QM chip breaker geometry, this insert is designed for productive turning operations on steel and stainless steel workpieces. Licensed machinists and CNC turning specialists are the primary installers.

This insert is suited for external and internal turning applications on steel (ISO material code P) as a primary workpiece material, with secondary application on stainless steel (ISO material code M). The QM chip breaker geometry supports a broad range of cutting conditions in both roughing and finishing passes. The T-Max P series is a well-established platform for indexable turning on CNC lathes and manual turning centers in industrial and job-shop environments. The ISO designation for this insert is DNMG 15 04 12-QM H13A. The insert is sold individually but carries a minimum order quantity of 10 units.

Compatibility

Designed for use in DNMG-style indexable turning toolholders that accept clamp and pin insert retention. Compatible with T-Max P series toolholders. ISO code DNMG 15 04 12-QM H13A confirms fitment with standard DNMG 15 04 toolholder pockets.

Installation Notes

Installation is performed by a machinist or CNC tooling technician following standard indexable insert changeout procedures. Shut down the spindle and confirm the machine is in a safe, locked-out state before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified for the toolholder to avoid cracking the carbide substrate. Verify insert seating and edge orientation before resuming cutting operations.
