SDMW09T308-A57 WKP25S milling insert — Tiger‑tec Silver for steel and cast iron, Walter Tools

A SDMW09T308-A57 WKP25S milling insert engineered for robust machining of steel and cast iron, with a 15° clearance and square 90° geometry for stable engagement.

• Tiger‑tec Silver coating for high wear resistance
• Optimised for steel and cast iron machining
• Square 90° form with 0.8 mm corner radius

Consistent edge life that keeps production running

The combination of the Tiger‑tec Silver coating and the WKP25S carbide grade is designed to extend tool life under the thermal and abrasive loads typical of steel and cast iron milling. The coated carbide reduces flank wear and helps maintain a stable cutting edge over longer production runs, which translates into fewer tool changes and higher uptime. This performance is particularly relevant for shops seeking predictable costs per component and a dependable process window for serial production.

Precision geometry for controlled chips and surface quality

The insert’s 15° clearance and its square 90° form deliver controlled entry angles and robust support at the cutting edge, reducing vibration and improving dimensional repeatability. The 0.8 mm corner radius provides a balance between strength and surface finish: a larger radius increases edge resilience and is beneficial for interrupted cuts, while the specified radius still permits good surface quality. The integrated A57 chipformer is configured to break and evacuate chips efficiently during face and profile milling; for those unfamiliar, a chipformer is a small geometry on the insert face that influences chip shape and flow, reducing heat build‑up and protecting the edge.

Broad material capability with practical handling benefits

Classified for material groups P (steel) and K (cast iron), this insert is suitable across a wide range of unalloyed and alloyed steels as well as common cast iron grades, making it a versatile choice for mixed‑batch production environments. The plate’s size designation 09, thickness T3 and tolerance class M ensure repeatable seating and compatibility with standard indexable milling toolholders, simplifying inventory and cutter set‑up. Walter Tools’ geometry and coating approach aim to offer process stability and predictable tool life, helping to reduce scrap rates and improve throughput in daily workshop practice.

FAQ

Which materials is this insert suited for?
The SDMW09T308-A57 WKP25S insert is specified for steel (group P) and cast iron (group K), reflecting the WKP25S grade and Tiger‑tec Silver coating optimised for these material families.

What benefit does the A57 chipformer provide?
The A57 chipformer promotes reliable chip breaking and evacuation during milling, which reduces heat concentration at the cutting edge and supports consistent surface finish when using the SDMW09T308-A57 WKP25S.

How does the 0.8 mm corner radius influence performance?
A 0.8 mm radius increases edge strength and supports interrupted cutting conditions while still permitting a satisfactory surface quality; it helps balance edge life and finish in typical milling operations.

Is this insert compatible with standard square milling cutters?
Yes, the square 90° form and tolerance class M make the insert suitable for standard indexable square milling cutter bodies that accept the SDMW09T308‑type geometry.

Can the SDMW09T308-A57 WKP25S be used on stainless steel?
Use on stainless steel is not specified for this grade in the available data; the insert is optimised for steel and cast iron, so an alternative grade should be selected for reliable stainless‑steel performance.
