SPMT09T308-F55 WKP25S Fräswendeschneidplatte by Walter Tools — Tiger‑tec Silver for steel & cast iron

A versatile SPMT09T308-F55 WKP25S milling indexable insert engineered for productive face and shoulder milling of steel and cast iron

• Tiger‑tec Silver coating for long tool life
• Designed for steel and cast‑iron machining
• Square 90° geometry for stable shoulder milling
• 0.8 mm corner radius for controlled chip flow

Maximise productivity with an advanced coated grade

The Tiger‑tec Silver technology combined with the WKP25S grade provides a coated carbide solution designed for high productivity in machining steel and cast iron. The coating reduces abrasive wear and increases thermal resistance, which translates to stable edge life and more consistent component quality over longer tool life. For workshops seeking fewer tool changes and predictable results, this combination supports efficient batch runs and repetitive processes. The insert’s classification for material groups P and K means it has been tailored to the cutting behaviours typical of unalloyed/alloyed steels and grey or ductile cast irons, with geometry and coating optimised to manage heat and chip formation effectively.

Geometry and chip control that improve surface finish

The square 90° insert form, paired with an 11° clearance and a 0.8 mm corner radius, offers mechanical stability for shoulder and face milling operations, reducing vibration and cutting forces. The integrated F55 chipbreaker promotes short, controlled chips that ease evacuation in interrupted cuts and minimise surface defects. Explaining the terms: the corner radius softens the cutting edge to avoid brittle chipping, while the clearance angle prevents rubbing behind the cutting edge. Together, these features support better surface finish and reduce the need for downstream grinding or polishing in volume production.

Seamless integration into production and reliable specification

With a tolerance class M and series designation Tiger‑tec Silver, the insert fits standard clamping systems for the corresponding insert size and form and is intended for repeatable, industrial use. The coated carbide construction ensures compatibility with typical feed and speed strategies for steels and cast irons, while the FK‑like robustness of WKP25S offers balanced wear resistance and edge strength.

FAQ

Which materials are recommended for this insert?
The SPMT09T308-F55 WKP25S from Walter Tools is recommended for machining steel (group P) and cast iron (group K), with the grade and coating tuned to those material behaviours.

What benefit does the Tiger‑tec Silver series provide?
The Tiger‑tec Silver series offers a coated carbide surface for improved wear resistance and thermal stability, helping the WKP25S grade to maintain stable edge life during repetitive milling tasks.

How does the F55 chipbreaker affect machining?
The F55 chipbreaker is shaped to promote short, controlled chips and reliable evacuation, which improves surface quality and reduces the risk of chip interference in shoulder and face milling.

Is this insert suitable for heavy interruption or finishing cuts?
The square 90° geometry and 0.8 mm corner radius give mechanical strength for interrupted cuts while providing a moderated edge for finishing; selection depends on the exact holder and cutting parameters.

Which series and grade should be chosen for mixed steel and cast‑iron production?
For mixed production of steel and cast iron, the WKP25S grade within the Tiger‑tec Silver series represents a balanced choice, combining abrasion resistance and edge robustness for both material groups.
