Sandvik Coromant 5732159 Turning Insert DNMG431-QM 1105

Product Description

The SANDVIK COROMANT 5732159 is a solid carbide turning insert with a TiAlN coating applied via PVD process, designed for external and internal turning operations on CNC lathes and turning centers. This DNMG431-QM insert features a 55-degree diamond shape, neutral hand orientation, and a QM chip breaker geometry optimized for steel and stainless steel machining. The inscribed circle measures 0.5 inches, insert length is 0.5946 inches, and the corner radius is 1/64 inch (0.0156 inches). Four cutting edges are available per insert. It is installed by licensed machinists and toolroom technicians in production and job-shop turning environments.

This insert is suited for turning steel, stainless steel, superalloys, and titanium workpieces. It fits the SANDVIK COROMANT T-Max P series toolholding system, which uses clamp and pin holding methods. Typical applications include roughing and semi-finishing passes on ferrous and high-temperature alloy components. The ISO code for this insert is DNMG 15 04 04-QM 1105, and it carries the UNSPSC code 23242105. It is a direct-fit replacement insert for T-Max P compatible toolholders used in precision turning on steel-class materials.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Disengage the machine spindle and confirm the turret is fully indexed and locked before replacing inserts. Use the appropriate Torx or hex key to release the clamping screw and pin per the toolholder manufacturer's instructions. Seat the insert fully against the pocket locating surfaces and verify clamp engagement before resuming cutting operations.
