SPMT060304-F55 WAK15 — milling insert (square 90°, for aluminium) | Walter Tools

The SPMT060304-F55 WAK15 is a square 90° milling insert designed for high‑efficiency machining of aluminium and other non‑ferrous metals

• WAK15 uncoated carbide for aluminium and NE metals
• Square 90° insert for stable milling
• 11° clearance angle reduces rubbing
• F55 chipbreaker for reliable chip control

Higher material removal with fewer interruptions

The combination of an uncoated carbide WAK15 grade and the F55 chipbreaker is tailored to address the common challenges of aluminium machining, such as built‑up edge and long stringy chips. The sharp cutting edge and a friction‑reducing geometry promote consistent material evacuation, which reduces the frequency of stoppages for chip clearing. As a result, cycle times improve while maintaining a consistent surface quality, making this insert an efficient choice for series production and short‑cycle high‑feed operations. The design supports higher feed rates without sacrificing process stability, which translates into measurable productivity gains.

Stable engagement and repeatable edge life

The square 90° geometry combined with a 0.4 mm corner radius provides a balance between edge strength and profile definition. The modest corner radius increases resistance to edge chipping compared with very small radii, yet still allows for good contour accuracy in pocketing and shoulder milling. The 11° clearance angle reduces rubbing on the flank face, lowering heat build‑up during engagement and helping to preserve edge integrity. These features together support predictable tool life and simpler process planning across batches — particularly valuable when repeatability is a priority.

Seamless integration into Walter’s grade system for reliable results

Designed for the Walter N‑grade system, this insert fits into toolsets and programmes that prioritise consistent results when machining non‑ferrous alloys. The WAK15 grade, an uncoated hardmetal, is specifically intended for aluminium and other NE materials, offering clean shearing and reduced material adhesion at the cutting edge. Integration into standard toolholders allows fast index changes, minimising downtime and supporting lean manufacturing routines. The insert’s characteristics favour both single‑pass and multi‑pass operations where surface finish and dimensional control are required.

FAQ

Is this insert suitable for machining aluminium alloys?
Yes. The SPMT060304‑F55 WAK15 insert is specified for aluminium and other non‑ferrous metals; the WAK15 uncoated grade is optimised to reduce material adhesion and generate manageable chips.

Does the insert require a special coating for aluminium?
No. The WAK15 grade is an uncoated hardmetal specifically chosen for aluminium applications to provide a sharp, low‑adhesion cutting edge without an additional coating.

What does the F55 chipbreaker provide in practice?
The F55 chipbreaker controls chip form and evacuation during milling of non‑ferrous materials, helping to avoid long stringy chips and reducing the need for manual interventions.

How does the 0.4 mm corner radius affect machining results?
A 0.4 mm corner radius offers increased edge strength compared with very small radii while maintaining good profile accuracy, improving resistance to chipping in typical aluminium milling tasks.
