MPHX080305-A57 WKP25S milling indexable insert — Tiger-tec Silver, 11° clearance, Walter Tools

MPHX080305-A57 WKP25S is an indexable milling insert designed for robust performance in the machining of steel and cast iron, optimised for reliable chip control and repeatable results

• Tiger-tec Silver coating for extended life
• WKP25S grade for steel and cast iron machining
• 11° clearance angle for reduced rubbing
• 0.5 mm corner radius for durable edge strength

Increased throughput through consistent cutting performance

The combination of the Tiger-tec Silver surface treatment and the WKP25S grade provides a measurable boost to machining efficiency. The coating reduces flank wear and enhances thermal resistance, which translates into longer tool life and fewer interruptions for tool changes. This indexed geometry supports stable cutting forces, contributing to a smoother production flow and predictable cycle times. The insert’s design is particularly advantageous in medium to high-volume environments where tool-life consistency directly affects overall equipment effectiveness.

Reliable chip control and material adaptability

Engineered for the ISO groups P and K, the insert is well suited to machining steel and cast iron, benefiting from tailored chipbreaker geometry that promotes short, controlled chips. The grade is a coated carbide composition optimised for the typical heat and strain encountered when cutting these materials. For users less familiar with grade nomenclature: WKP25S denotes a carbide substrate with a multilayer protective coating designed to resist abrasive wear and thermal degradation. The result is improved surface finish and fewer burrs, reducing downstream rework and finishing effort.

Practical geometry for robust roughing and finishing

With an effective 0.5 mm corner radius and a compact size 08 profile, the insert offers a balance between edge strength and cutting accuracy; the modest radius helps absorb impact loads while enabling acceptable surface quality in interrupted cuts. The 11° clearance reduces flank contact and heat generation during engaged cutting, lowering the risk of built-up edge and enabling stable cuts across varied feed rates. Marked with a toleranzklasse H and produced in the Tiger-tec Silver series, the specification supports consistent replacement and predictable tool management in toolholding systems.
