SPMT09T308-F55 WKP35G indexable milling insert for steel and cast iron — Walter Tools

The SPMT09T308-F55 WKP35G is a square 90° indexable milling insert from Walter Tools, optimised for productive machining of steel and cast iron.

• Tiger·tec Gold coated grade WKP35G
• For steel and cast iron applications
• Square 90° form with 0.8 mm corner radius
• 11° relief and F55 chipbreaker for stable cuts

Maximising productivity with a premium coated grade

The combination of the Tiger·tec Gold coating and the WKP35G carbide grade delivers high abrasion resistance and improved thermal stability when machining steels and cast iron (ISO groups P and K). The coating technology reduces flank wear under sustained loads, which helps to extend tool life and maintain consistent cutting performance. For manufacturers seeking reduced tool-change frequency and predictable process windows, this insert offers a measurable advantage in production environments, supporting higher uptime and steadier component output.

Geometry that supports surface quality and robust cutting

The square 90° plate form with a 0.8 mm corner radius increases edge strength for intermittent and heavier cuts while preserving the potential for a good surface finish. The 11° relief angle reduces rubbing at the flank and helps avoid built-up edge in many steel operations. The F55 chipbreaker is designed to control chip formation, promoting short, manageable chips in medium to heavy milling passes. Together these features make the insert suitable for stable cutting regimes where both tool life and part quality matter.

Practical benefits for shop-floor efficiency

As an indexable milling insert, the product enables rapid re-indexing and economical edge utilisation compared with solid tools. The specified T3 plate thickness and size 09 match common cutter bodies, simplifying inventory and replacement planning. The M tolerance class ensures repeatable dimensional behaviour for predictable tool set-ups. These operational benefits reduce downtime, support leaner tool stocks and contribute to a faster return on machining cycles in jobbing and serial production alike.

Application advice and process integration

This insert is intended for machining a wide range of steel grades and cast iron, covering typical unalloyed and alloyed steels as well as abrasive cast materials. The WKP35G grade favours stable chip formation and is suitable for both roughing and semi-finishing passes where a balance of wear resistance and edge toughness is required. For optimised cutting parameters and clamping recommendations tailored to specific machines or geometries, consult Metav Werkzeuge’s technical advisors to ensure the best match between insert, cutter body and machining strategy.

FAQ

What materials is this insert suited for?
The SPMT09T308-F55 WKP35G insert from Walter Tools is specified for ISO material groups P (steel) and K (cast iron), making it suitable for a broad range of unalloyed and alloyed steels and many cast materials.

How does the F55 chipbreaker influence chip control?
The F55 chipbreaker integrated in the SPMT09T308-F55 WKP35G helps form shorter, controllable chips under medium to heavy milling conditions, which reduces chip entanglement and improves process security.

Is the grade coated and what benefit does the coating provide?
Yes, the WKP35G grade is part of the Tiger·tec Gold coating technology; this coating improves abrasion resistance and heat management, contributing to longer tool life and consistent cutting performance.

What effect does the 0.8 mm corner radius have on the cut?
A 0.8 mm corner radius increases edge robustness for roughing and interrupted cuts while still allowing a respectable surface finish, helping to avoid premature chipping at the edge.
