SDMT09T308‑D57 WKP35G indexable milling insert by Walter Tools — Tiger‑tec Gold for steel and cast iron

SDMT09T308‑D57 WKP35G is a square 90° indexable milling insert from the Tiger‑tec Gold series, designed for high‑productivity face and shoulder milling of steels and cast‑iron materials.

• Tiger‑tec Gold coating for wear resistance
• Grade WKP35G optimised for steel and cast iron
• Square 90° form with 0.8 mm corner radius
• D57 chipbreaker for stable chip control

Longer tool life through advanced grade technology

The Tiger‑tec Gold series, embodied in the WKP35G grade, combines a wear‑resistant coating with a robust substrate to reduce flank and crater wear under typical steel and cast iron cutting conditions. This insert offers improved process consistency: the coating slows abrasive wear while the substrate maintains edge stability, resulting in fewer tool changes and a higher effective cutting time per tool. The result is measurable productivity gain with predictable performance in serial production.

Geometry that stabilises the cut and improves surface quality

A square 90° insert geometry with a 0.8 mm corner radius and 15° relief provides a stable cutting edge that dampens vibration and supports predictable chip flow. The D57 chipbreaker is designed for controlled chip formation in both short and medium‑chip scenarios, helping to avoid entanglement and reduce rework. For the workshop, this geometry translates into better surface finish and more reproducible part quality when face milling or finishing shoulders.

Practical advantages for process planners and operators

Tolerance class M ensures dimensional consistency across batches, simplifying tool‑holder setup and repeatability in automated cells. The insert thickness T3 and proven chip control enable reliable performance with standard Walter Tools tool holders. Compatibility with material groups P (steel) and K (cast iron) makes this grade a versatile choice for mixed‑material production. The combination of a coated carbide grade and the specified geometry provides a cost‑effective solution where stable cycle times and low scrap rates are priorities.

FAQ

What materials is this insert suited for?
The SDMT09T308‑D57 WKP35G insert is engineered for ISO groups P (steel) and K (cast iron), with the WKP35G grade optimised to manage the heat and abrasive wear typical of these materials.

How does the D57 chipbreaker affect machining?
The D57 chipbreaker promotes reproducible chip segmentation and evacuation, reducing the risk of surface damage and enabling more stable cycle times when using the SDMT09T308‑D57 WKP35G in milling operations.

What benefit does the 0.8 mm corner radius provide?
A 0.8 mm corner radius increases edge strength and improves surface finish during finishing passes; it balances robustness and detail to suit a range of face‑milling tasks with the SDMT09T308‑D57 geometry.

Is the Tiger‑tec Gold technology mainly a coating or substrate feature?
Tiger‑tec Gold is a coating technology applied to a carefully matched carbide substrate; for the SDMT09T308‑D57 WKP35G this combination enhances wear resistance and edge stability under elevated temperatures common when machining steels and cast irons.
