Walter 7169072 Milling Insert XNMU0705ANN-F57 WKP35G

Product Description

The WALTER 7169072 is a solid carbide milling insert in the XNMU series, carrying ANSI and ISO designation XNMU0705ANN-F57 with manufacturer grade WKP35G. The insert features a heptagon shape with 14 cutting edges, a negative rake angle of 16 degrees, and a CVD-applied TiAlN and TiN dual-layer coating for extended tool life in demanding applications. At 4.60 mm (0.1970 inches) thick with an inscribed circle of 14.50 mm (0.571 inches), it delivers a maximum depth of cut of 6.98 mm (0.275 inches). The double-sided, neutral-hand geometry makes it suitable for high-productivity face and shoulder milling operations.

This insert is designed for machining steel and cast iron, corresponding to ISO material groups P and K. It is well-suited for production milling environments where long edge life and consistent surface finish are required. The F57 chip breaker geometry and chamfered-and-honed cutting edge style help control chip formation across a range of cutting conditions typical in job shop and high-volume manufacturing settings. Compatible cutter series is M3024.

• Maximum depth of cut 6.98 mm (0.275 inches); corner radius 0.80 mm (0.031 inches)

Compatibility

Designed for use with the WALTER M3024 cutter series. Rated for primary workpiece materials steel and cast iron (ISO material codes P and K). Conforms to ANSI and ISO standards with designation XNMU0705ANN-F57 WKP35G.

Installation Notes

Installation is performed by machining technicians or toolroom personnel using the screw-clamp holding method standard to the M3024 cutter body. Power down and lock out the machine spindle before seating or indexing inserts. Inspect the insert pocket and clamping screw for wear or debris before installing a new edge. Follow the cutter manufacturer torque guidelines for the clamping screw as specified in the toolholder documentation.
