Walter 7469966 SPMW070308-A67 WKP25S Milling Insert

Product Description

The WALTER 7469966 is a solid carbide milling insert carrying ANSI and ISO designation SPMW070308-A67 WKP25S. It features a square insert shape with a 90-degree included angle, a neutral hand orientation, and a positive rake geometry with a honed cutting edge style. The insert is CVD-coated with a TiCN / Al2O3 / TiCN multilayer stack under the WKP25S manufacturer grade, targeting P25 and K25 material classifications. Four usable cutting edges per insert make it a cost-effective choice for production milling operations. Licensed machinists and CNC tooling technicians use this insert in face milling, shoulder milling, and general-purpose indexable milling applications on steel and cast iron workpieces.

This insert is intended for milling operations on steel and cast iron, covering both primary workpiece material codes P and K. Its A67 chip breaker geometry suits medium to semi-finishing cuts at controlled depths up to 0.3125 inches. The WKP25S grade with CVD multilayer coating provides wear resistance and thermal stability in continuous and interrupted cut scenarios typical in job-shop and production environments. It is installed using a screw-holding method, which is standard across a wide range of indexable milling cutter bodies designed for SPMW-style inserts.

Key Features

• Solid carbide substrate with CVD-applied TiCN / Al2O3 / TiCN multilayer coating for wear and heat resistance
• WKP25S grade rated for P25 and K25 material applications including steel and cast iron
• Square SPMW insert shape with 90-degree included angle and positive rake for lower cutting forces
• Four cutting edges per single-sided insert maximize tooling economy
• A67 chip breaker geometry suited to medium and semi-finishing milling passes
• Honed cutting edge style reduces micro-chipping on entry and exit

Compatibility

Designed for indexable milling cutter bodies that accept SPMW-style inserts with a screw-holding method, conforming to ANSI and ISO standards for the SPMW 070308 insert size family.

Installation Notes

Installation is performed by licensed machinists or CNC tooling technicians following the cutter body manufacturer torque guidelines for the insert-clamping screw. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the cutter body pocket seat for chips or damage before seating the new insert. Handle carbide inserts with care to avoid edge chipping prior to first use.
