SPMT09T308-F55 WAK15 — Indexable milling insert for aluminium (Walter Tools)

The SPMT09T308-F55 WAK15 is a square indexable milling insert engineered for high-performance machining of aluminium and other non‑ferrous metals, offering a sharp cutting edge and controlled chip formation for efficient production.

• Uncoated carbide grade WAK15 for non-ferrous metals
• F55 chipbreaker for stable chip control
• Square 90° shape with 0.8 mm corner radius
• 11° clearance angle for sharp cutting edges

High-efficiency aluminium machining with predictable results

The WAK15 grade is an uncoated carbide designed specifically for machining aluminium and non‑ferrous metals, combining a very sharp cutting edge with low adhesion tendencies. The insert’s F55 chipbreaker promotes consistent chip formation and evacuation, reducing rework and downtime. For manufacturers seeking measurable gains in throughput, this geometry translates directly into shorter cycle times and reduced manual chip handling. The design supports high feed rates typical in modern milling operations while maintaining a stable cutting process.

Improved surface quality and reduced burr formation

A square 90° insert with a 0.8 mm corner radius produces robust corner strength while maintaining a fine finish on machined faces. The moderate corner radius balances edge life and surface integrity, helping to minimise secondary deburring on thin-walled aluminium components. The 11° clearance angle reduces rubbing and built-up edge, which in turn supports consistent surface roughness and repeatable part quality across batches—beneficial for aerospace, automotive and precision engineering suppliers working with non‑ferrous alloys.

Robust tool geometry for reliable cycle times

Integrated within the Walter N‑series, this insert benefits from a geometry optimised for stable chip formation and predictable wear behaviour. The combination of grade and chipbreaker is chosen to limit heat generation and prevent material adhesion, extending usable cutting life in many aluminium alloys. For production environments where process stability is measured in repeatability and part conformity, the insert delivers consistent tool life and predictable replacement intervals, simplifying tool management and inventory planning.

Practical integration and handling in the shop

The insert’s designation and compact square format make it straightforward to integrate into common milling cutters and toolholders. Its standard dimensions (plate size 09, thickness T3) and tolerance class M support interchangeability within existing ISO‑based systems, reducing qualification time for new tools. The straightforward uncoated carbide composition also eases regrind or inspection procedures. For workshops aiming to scale production or switch between aluminium grades, the insert offers a blend of accessibility and performance without requiring specialised coolant strategies.

FAQ

What materials is this insert best suited for?
The SPMT09T308-F55 WAK15 insert is optimised for aluminium and non‑ferrous metals, utilising the WAK15 uncoated carbide grade for low adhesion and reliable cutting behaviour.

How does the F55 chipbreaker improve machining?
The F55 chipbreaker on the insert promotes stable chip formation and evacuation, which helps maintain consistent machining cycles and reduces the risk of chip-related interruptions.

Is the insert compatible with standard indexable milling cutters?
Yes, the square 90° format and standard plate size (09) allow compatibility with common ISO‑based milling cutters and toolholders designed for indexable inserts.

What benefit does the 11° clearance angle provide?
The 11° clearance angle reduces flank contact and built‑up edge formation, supporting superior surface finish and prolonged cutting edge integrity when machining aluminium alloys.
