CNMU080508-D57T WKP35S – Milling insert for steel and cast iron | Walter Tools (Tiger·tec Silver)

The CNMU080508-D57T WKP35S is a rhombic 80° milling insert engineered for productive face and peripheral milling of steel and cast iron, featuring a Tiger·tec Silver coated carbide grade for enhanced wear resistance.

• Tiger·tec Silver coating for stable cutting
• WKP35S grade for steel and cast iron machining
• Rhombic 80° form with 0.8 mm corner radius
• Negative 0° rake for heavy-duty performance

Consistent performance on steel and cast iron

The combination of the WKP35S coating grade and the Tiger·tec Silver technology delivers predictable wear behaviour when machining group P (steel) and group K (cast iron) materials. Designed for the thermal and mechanical conditions typical of steel cutting, the grade offers optimised chip formation and abrasion resistance, reducing unplanned tool changes and helping to maintain steady cycle times in medium- to high-volume production environments.

Geometry that stabilises cutting and extends life

The rhombic 80° form, paired with a 0.8 mm corner radius and a negative 0° rake, provides a robust cutting edge that resists chipping under interrupted cuts and heavy engagement. This geometry supports consistent surface quality and repeatable insert indexing, while the defined corner radius helps to distribute cutting forces, lowering edge stress and improving component finish in both face and shoulder milling operations.

Productivity and process security advantages

A Tiger·tec Silver coated carbide insert such as this promotes longer intervals between regrinds and simplifies process planning. The chipbreaker D57T assists in controlled chip detachment for the typical chip types encountered in steel and cast iron, reducing the risk of built-up edge and contributing to a stable machining process. Together, these features support higher material removal rates and fewer process interruptions, which translates into improved overall productivity on the shop floor.

Application guidance and compatibility

This insert is produced in the CNMU08 form factor and is compatible with milling cutters designed for indexable inserts of that designation. The WKP35S grade is catalogued for steel and cast iron; final feed and speed recommendations depend on the specific workpiece grade and machine capability. Where application conditions are unusual or material specifications are critical, Metav Werkzeuge’s technical team can provide tailored recommendations to match cutter bodies, clamping systems and process parameters.

FAQ

What materials is this insert suitable for?
The CNMU080508-D57T WKP35S is designed for machining steel (ISO group P) and cast iron (ISO group K) using the Tiger·tec Silver coated carbide grade.

What is the purpose of the rhombic 80° form?
A rhombic 80° form gives versatile cutting geometry for both face and peripheral milling, offering a compromise between accessibility and cutting-edge strength for repeatable results.

How does the WKP35S grade affect machining?
WKP35S, as a Tiger·tec Silver coated grade, provides improved wear resistance and reliable edge behaviour, especially under the heat and abrasion conditions typical when machining steel and cast iron.

Which chipbreaker is used and why does it matter?
The insert features the D57T chipbreaker, which is tuned to promote controlled chip detachment for the chip forms common in steel and cast iron, contributing to process stability and surface quality.
