Walter 7924352 Carbide Milling Insert Spmt 060304 WSP45G

Product Description

The WALTER 7924352 is a single-sided square carbide milling insert in SPMT style, grade WSP45G, designed for high-performance face and shoulder milling operations. It features a PVD-applied TiAlN/Al2O3/ZrN multilayer coating that delivers thermal resistance and wear protection across demanding cutting conditions. The insert carries the F55 chip breaker geometry and a 0.0157-inch (0.40 mm) corner radius, with four usable cutting edges per insert. It is screw-held in the toolholder and suited for machine shops and production facilities running CNC milling equipment on ferrous and high-temperature alloy workpieces.

This insert is intended for milling steel, stainless steel, and super alloys (ISO material groups P, M, and S). The SPMT 060304 size designation indicates a 0.25-inch inscribed circle and a maximum depth of cut of 0.25 inches (6.35 mm), making it appropriate for light-to-moderate radial engagement passes on indexable milling cutters. It suits production environments where insert change-out speed and consistent edge geometry are priorities, particularly in aerospace, energy, and general machining applications working with difficult-to-cut alloys.

Key Features

• WSP45G grade carbide substrate with PVD TiAlN/Al2O3/ZrN multilayer coating for wear and heat resistance
• F55 chip breaker geometry optimized for controlled chip formation in steel and stainless steel
• Four cutting edges per single-sided insert for extended tooling economy
• Neutral cutting direction and neutral hand for versatile milling cutter compatibility
• 0.0157-inch (0.40 mm) corner radius reduces edge stress at entry and exit
• Screw-held mounting method for positive, repeatable insert seating

Compatibility

Designed as an OEM-style replacement insert for SPMT-style indexable milling cutters accepting 060304 inserts. ISO catalog reference: SPMT060304-F55 WSP45G. Confirm toolholder pocket geometry and screw hole diameter (2.80 mm) before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified tightening procedure for screw-held SPMT inserts. Inspect the pocket seat and clamping screw threads for damage before seating a new edge.
