Walter 7021461 DNGG150408-MS3 WSM01 Carbide Turning Insert

Product Description

The WALTER 7021461 is a solid carbide turning insert in the DNGG-MS3 series, designed for high-performance metal cutting in demanding production environments. It carries the ISO designation DNGG150408-MS3 WSM01 and ANSI code DNGG432-MS3 WSM01. The insert features a TiAlN, Al2O3, and ZrN multi-layer coating applied via PVD process, delivering strong heat and wear resistance at the cutting edge. The 55-degree diamond (rhombic) shape provides four usable cutting edges with a neutral hand orientation, a honed cutting edge style, and a 0.8 mm corner radius. This insert is installed by machinists and CNC turning specialists in roughing and medium machining operations.

This insert is suited for roughing and medium machining applications on stainless steel and superalloys and titanium as primary workpiece materials. Secondary materials include steel, non-ferrous metals, and hard materials. Supported operations include turning, facing, boring, and back turning. The MS3 chip breaker geometry is engineered for chip control across these demanding material groups, making this insert a practical choice for shops running high-alloy or difficult-to-machine workpieces on CNC lathes and turning centers.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before installing the insert. Follow the toolholder manufacturer's clamping torque specifications and verify insert seating before returning the machine to service.
