Walter 6944743 Turning Insert DNMG150408-RM5 WSM30S Carbide

Product Description

The WALTER 6944743 is a solid carbide coated turning insert in the DNMG150408-RM5 configuration, graded WSM30S and part of the Tiger-tec Silver series. It features a 55-degree diamond insert shape with a neutral hand orientation and a PVD-applied TiCN, Al2O3, and Al multilayer coating. The insert measures 15.5 mm (0.6104 inches) in length with a 1/2-inch inscribed circle and a 1/32-inch (0.0315 inch) corner radius. With four cutting edges and a chamfered and honed cutting edge style, it is designed for high-productivity turning operations in demanding materials. Licensed machinists and CNC turning specialists are the primary installers of this insert type.

This insert is engineered for primary use in stainless steel and superalloys and titanium workpiece materials, with secondary suitability for steel. The RM5 chip breaker geometry and negative rake angle support stable cutting in materials that generate high cutting forces and heat. Typical applications include turning, facing, boring, and back turning on CNC lathes and turning centers in both production and job-shop environments. The WSM30S grade targets ISO material groups M30, S30, and P30, making it a versatile choice across a range of alloy families commonly encountered in aerospace, medical, and general industrial machining.

Compatibility

Designed as an OEM-style replacement and direct-fit turning insert for toolholders accepting DNMG-style inserts with a 1/2-inch inscribed circle, 3/16-inch insert thickness, and clamp or pin holding methods per ANSI and ISO standards.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and locked out before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to seat the insert correctly - do not overtighten by hand. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper contact and runout.
