SDMT09T308-F57 WKP25S milling indexable insert – Square 90°, 15° relief, Tiger‑tec Silver (Walter Tools)

A high-performance milling indexable insert, SDMT09T308-F57 WKP25S, developed for productive machining of steel and cast iron in general milling operations.

• Tiger‑tec Silver coating technology
• Designed for steel and cast iron
• Square 90° insert, corner radius 0.8 mm
• 15° relief angle, chipbreaker F57

Deliver consistent metal removal with a coated, wear‑resistant grade

The Tiger‑tec Silver grade WKP25S combines a durable coating with a coated carbide substrate to deliver stable tool life and predictable wear rates when machining steel and cast iron. The specific combination of substrate and surface finish improves resistance to abrasive wear and thermal loading typical in P‑ and K‑class materials. With the integrated chipbreaker F57, chip formation is controlled to reduce interruptions and improve surface integrity, helping to maintain cycle times and reduce secondary operations.

Exact geometry for repeatable results and secure clamping

The square 90° geometry with a 0.8 mm corner radius and 15° relief angle creates a robust cutting edge suitable for shoulder milling and general profiling where edge strength is required. The insert’s T3 thickness and size code 09 provide mechanical stability, while tolerance class M ensures interchangeability and reproducible seat fit in standard toolholders. These dimensional characteristics reduce vibration and enable predictable process windows, which supports both throughput and part quality in serial production.

Practical integration in shop‑floor tooling systems

Built as a conventional indexable insert, this plate fits established milling tool systems and is straightforward to replace during tool changes. The grade’s focus on stable chip formation and broad workpiece compatibility cuts set‑up time and minimises trial‑and‑error when switching from roughing to finishing passes. For manufacturers seeking to reduce downtime, the combination of a proven coated carbide grade and a dedicated chipbreaker offers a clear route to longer edge life and consistent surface finish with fewer tool interventions.

FAQ

What materials is this insert suitable for?
The SDMT09T308-F57 WKP25S insert (Walter Tools, Tiger‑tec Silver) is designed for machining steel (P) and cast iron (K) as indicated by its grade and chipbreaker geometry.

How does the WKP25S grade affect tool life?
WKP25S, as part of the Tiger‑tec Silver family, provides a wear‑resistant coating and substrate pairing that extends edge life under thermal and abrasive loads typical when machining steel and cast iron.

What is the purpose of the F57 chipbreaker?
The F57 chipbreaker promotes controlled chip formation and evacuation, reducing the risk of entanglement and supporting stable cutting conditions in both roughing and semi‑finishing operations.

Can this insert be used for shoulder milling?
Yes; the square 90° geometry and 0.8 mm corner radius make the insert suitable for shoulder milling and other operations requiring robust cutting edges.

Is the SDMT09T308-F57 compatible with standard holders?
The insert follows common indexable plate dimensions and tolerance class M, allowing compatibility with standard T‑type milling holders designed for this plate size.
