SDMT09T304-F57 WKP35G milling insert — Tiger‑tec Gold, square 90° (for steel & cast iron) — Walter Tools

The SDMT09T304-F57 WKP35G is a square 90° milling insert engineered for efficient metal removal in steel and cast iron, combining a Tiger‑tec Gold coating with a defined 15° clearance for stable cutting performance.

• Tiger‑tec Gold coating for extended life
• Optimised for steel and cast iron machining
• Square 90° form with 0.4 mm corner radius

Longer tool life through advanced coating and grade

The combination of the Tiger‑tec Gold coating and the WKP35G coated‑carbide grade delivers increased resistance to abrasive and adhesive wear, improving interval lengths between indexings. This translates into a measurable productivity gain in continuous operations where downtime for tool change represents a real cost. The insert’s surface engineering reduces built‑up edge formation and helps maintain cutting geometry under elevated temperatures typical for machining steel and cast iron, supporting stable tool life and consistent part quality.

Stable chip control and reliable process security

With an integrated chipbreaker F57 and a square cutting form, the insert ensures predictable chip shape and evacuation during medium to heavy milling passes. Predictable chips reduce the risk of rework and machine downtime and simplify coolant and machine setup. The geometry, combined with the coated carbide specification, is optimised for the typical thermal and mechanical demands of P and K ISO material groups, providing reliable material removal rates and improved process security in production environments.

Geometry tuned for surface quality and dimensional repeatability

The square 90° shape and 0.4 mm corner radius produce a balance between robustness and edge definition: the radius supports strength at the cutting edge while allowing acceptable surface finish on the workpiece. The defined 15° clearance angle minimises rubbing on the flank face, lowering cutting forces and heat generation. Together, these features contribute to consistent component finish and dimensional stability across runs, especially when machining cast components and general steels where chip behaviour and edge integrity are critical.

Practical integration and expert support for production use

The insert is supplied in the Tiger‑tec Gold series format and is compatible with standard SDMT‑style milling toolholders, making it straightforward to integrate into existing tool inventories. For customers seeking optimisation, Metav Werkzeuge provides machining advice and application recommendations to align cutting data with part geometry and machine capability. Technical consultancy can help select cutting parameters that leverage the insert’s wear resistance and chip control to reduce overall machining cost per part.

FAQ

What materials is this insert suitable for?
The SDMT09T304-F57 WKP35G insert from Walter Tools is optimised for ISO material groups P (steel) and K (cast iron), offering balanced wear resistance and chip control for these materials.

How does the Tiger‑tec Gold coating benefit production runs?
The Tiger‑tec Gold coating on the WKP35G grade improves resistance to abrasive and adhesive wear, which lengthens tool life and supports longer uninterrupted production cycles with stable cutting behaviour.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius provides enhanced edge strength while still allowing a good surface finish on milled parts; it represents a compromise between robustness and the achievable finish level.

Is the insert compatible with standard SDMT holders?
Yes, the insert follows SDMT geometry and is compatible with standard SDMT‑style milling bodies designed for square 90° inserts and T3 thickness.
