SDMT06T204‑F57 WKP25S milling insert (Tiger‑tec Silver) by Walter Tools — for Stahl and cast iron, 15° relief

The SDMT06T204‑F57 WKP25S milling insert is a Tiger‑tec Silver coated, square 90° indexable plate developed for productive face and shoulder milling in Stahl and cast iron applications.

• Tiger‑tec Silver coated carbide grade WKP25S
• Optimised for Stahl and cast iron machining
• 15° relief angle with 0.4 mm corner radius
• Square insert 90° for versatile face milling

Consistent machining results through a modern coated grade

The Tiger‑tec Silver coating together with the WKP25S grade offers a balanced combination of wear resistance and toughness. This coated carbide formulation is engineered to control thermal loads and abrasive wear during continuous cutting, which translates into longer tool life and fewer index changes on the machine. For production environments requiring repeatable surface quality, the coated grade reduces process variation and helps to maintain component tolerances over longer batches.

Geometry and chip control that simplify set‑up and boost productivity

The square 90° plate geometry with a 15° relief and a 0.4 mm corner radius provides a robust edge for face and shoulder milling while enabling predictable engagement with the workpiece. The integrated chipbreaker F57 is designed to support short, controllable chip formation in cast iron and compact chips in Stahl, improving evacuation and reducing the risk of re-cutting. These geometric choices shorten set‑up times and lower the incidence of machining interruptions, improving overall line throughput.

Robust tolerance and series features for industrial use

Manufactured to tolerance class M and delivered in the T2 thickness variant, this insert supports stable clamping and repeatable indexing in automated toolholders. Being part of the Tiger‑tec Silver series and specified for materials P (Stahl) and K (cast iron), the insert is positioned for shops that prioritise process security and uptime. Walter Tools' design focus on a stable cutting edge and broad material coverage makes this plate suitable for mixed‑production workshops where flexibility and reliable tool life are essential.

FAQ

Which materials can be machined with this insert?
The SDMT06T204‑F57 WKP25S milling insert is specified for machining P (Stahl) and K (cast iron), making it suitable for a wide range of unalloyed and alloyed Stahl grades and typical cast‑iron components.

What advantages does the Tiger‑tec Silver coating offer?
Tiger‑tec Silver on the WKP25S grade improves wear resistance under thermal load and helps maintain a stable cutting edge, extending the effective life of the insert in continuous milling operations.

How does the F57 chipbreaker affect machining performance?
The F57 chipbreaker promotes short, controlled chips in cast iron and aids chip management in Stahl, reducing risk of chip entanglement and improving surface finish consistency when using the SDMT06T204‑F57 WKP25S.

Is the insert suitable for high‑speed machining?
The combination of coated carbide and its geometry provides good thermal stability; suitability for high‑speed conditions depends on the specific machine, spindle capability and the Stahl or cast‑iron grade being machined.

What does the 0.4 mm corner radius mean for component finish?
A 0.4 mm corner radius offers a compromise between edge strength and achievable corner definition, supporting robust cutting while maintaining acceptable surface quality in typical face‑milling operations.
