Walter 5854978 Milling Insert WKP35S Solid Carbide

Product Description

The WALTER 5854978 is a solid carbide milling insert in the ODHT series, designated by ANSI and ISO code ODHT0605ZZN-F57 WKP35S. This single-sided, octagon-shaped insert features 8 cutting edges, a neutral hand orientation, a positive rake angle of 16 degrees, and a chamfered and honed cutting edge style. Manufactured in grade WKP35S, it carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiCN for extended wear resistance in demanding milling operations. With an inscribed circle of 0.625 inches and a thickness of 0.219 inches, this insert suits production milling of steel and cast iron at moderate to aggressive depths of cut up to 0.259 inches.

This insert is designed for face milling and shoulder milling applications in steel and cast iron workpieces, covering ISO material groups P and K. It is used in production environments where tool life and edge consistency are critical, such as automotive, general machining, and heavy component manufacturing. The F57 chip breaker geometry promotes positive cutting action and efficient chip evacuation. Cutter series compatibility is listed as F2010 and M5004. Installation is performed by licensed or qualified machining professionals in CNC milling applications.

Key Features

• Octagon insert shape with 8 cutting edges for maximum index value per insert
• CVD multilayer coating: TiCN, Al2O3, TiCN for wear and crater resistance
• Positive rake angle of 16 degrees with chamfered and honed edge prep for smooth, stable cutting
• 15-degree relief angle with neutral hand for broad application flexibility
• F57 chip breaker geometry optimized for steel and cast iron milling
• Screw-held mounting for secure, repeatable seating in compatible toolholders

Compatibility

Compatible with WALTER cutter series F2010 and M5004. Intended for milling of steel and cast iron workpieces per ISO material groups P35 and K35.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine in a locked-out, zero-energy state. Use the appropriate torx or hex key per the toolholder manufacturer specification to secure the clamping screw. Inspect the insert pocket seat for debris or damage before seating the insert. Confirm the correct insert orientation and chip breaker position before resuming cutting operations.
