SDMT120420-F57 WKP35G — Milling insert, Tiger·tec Gold, Walter Tools

The SDMT120420-F57 WKP35G is a square 90° milling insert engineered for high-productivity machining of steel and cast iron in demanding milling operations.

• Tiger·tec Gold coating for wear resistance
• Coated-carbide WKP35G grade for long life
• Optimised F57 chipbreaker for consistent chips
• Square 90° form with 15° relief and r 2 mm

Longer tool life through advanced coating technology

The combination of Tiger·tec Gold coating and the WKP35G grade creates a cutting edge that is resistant to the typical abrasive and thermal stresses encountered when machining steel and cast iron. The coated-carbide construction reduces flank and crater wear, which translates into fewer tool changes and improved process uptime. For production-focused shops, this results in a measurable improvement in overall tool economy while maintaining consistent cutting performance across batches.

Consistent surface quality and reproducible geometry

The square 90° form and a corner radius of 2 mm deliver robust edge strength and predictable engagement in slotting and face milling operations. The insert’s 15° relief geometry supports stable cutting conditions and helps to maintain surface finish repeatability. With tolerance class M, the insert fits standard toolholders with reliable seating, reducing variation between successive assemblies and supporting reproducible component quality.

Chip control that supports faster cycle times

Equipped with the F57 chipbreaker, the insert controls chip formation to favour short, manageable chips when cutting both steel and cast iron. Improved chip control reduces interruptions, protects the workpiece and toolholder, and facilitates safer, higher-feed machining strategies. The result is an efficient, deterministic process that supports higher material removal rates without compromising tool life.

Application scope and operational guidance

The insert is designed primarily for machining applications classified under ISO group P (steel) and K (cast iron), reflecting its balanced toughness and abrasive-wear resistance. The coated-carbide substrate and P/K suitability make the insert appropriate for a wide range of operations—from medium-duty finishing to more productive roughing passes—provided cutting parameters are adapted to the workpiece material and machine capability. For specification of feed and speed windows, refer to tooling charts or consult application engineering.
