Walter 7347318 Milling Insert ODMT0504ZZN-D57 WKP35G Carbide

Product Description

The WALTER 7347318 is a solid carbide octagon milling insert carrying the ANSI/ISO designation ODMT0504ZZN-D57 in grade WKP35G. Engineered for steel and cast iron machining, this single-sided insert features a CVD-applied TiAlN and TiN multilayer coating for thermal resistance and wear life at elevated cutting speeds. The neutral-hand geometry delivers a positive rake angle of 10 degrees with a honed cutting edge style, reducing cutting forces and promoting a clean finish. With 8 usable cutting edges and a D57 chip breaker, the insert offers strong economics per edge in high-production milling operations. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is suited for face milling, shoulder milling, and general-purpose milling of steel and cast iron in both roughing and semi-finishing applications. The WKP35G grade aligns with material grades P35 and K35, making it appropriate for a broad range of ferrous workpiece materials encountered in job shop and production environments. It is compatible with the M5004 cutter series and seats via screw-clamping into indexable milling toolholders designed for the ODMT insert style and size code 0504. The 135-degree included angle of the octagon shape provides good edge strength for interrupted cuts.

Key Features

• Solid carbide substrate with CVD TiAlN and TiN coating for wear resistance in steel and cast iron
• 8 cutting edges per insert with neutral hand orientation for maximum edge utilization
• D57 chip breaker geometry optimized for positive rake milling with a 10-degree rake angle
• Corner radius of 0.031 inches (0.80 mm) balances edge strength and surface finish
• Maximum depth of cut of 0.207 inches (5.26 mm) supports both roughing and semi-finishing passes
• Conforms to ANSI and ISO standards under code ODMT0504ZZN-D57 for broad toolholder interchangeability

Compatibility

Designed for use with the M5004 cutter series and toolholders accepting the ODMT insert style in size code 0504. Primary workpiece material compatibility covers steel (P) and cast iron (K) per ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully in the pocket and secure with the clamping screw using the appropriate Torx or hex key as specified by the toolholder manufacturer - do not overtighten. Inspect the insert pocket for chips, damage, or wear before seating a new edge.
