SPKT1204AZN WAK15 WAK15 Wendeplatten - Walter Tools

Precision machining of aluminium benefits from the combination of a sharp, uncoated carbide grade and a 11° relief for reduced rubbing; the square 90° form ensures stable seating and consistent chip formation.

SPKT1204AZN WAK15 – Square 90° milling insert for aluminium and non‑ferrous metals by Walter Tools

A SPKT1204AZN WAK15 indexable milling insert engineered for high‑precision machining of aluminium and other non‑ferrous metals

• Square 90° design for secure seating
• 11° relief angle reduces rubbing
• Uncoated carbide WAK15 for aluminium
• Walter N‑series optimised for non‑ferrous machining

Consistent chip control for aluminium production

The SPKT1204AZN WAK15 combines a very sharp edge geometry with an uncoated carbide grade specifically developed for aluminium and other non‑ferrous metals, which improves chip breakage and reduces built‑up edge. The result is a predictable chip flow and fewer interruptions during high‑volume runs, helping to maintain cycle times. By using a grade designed for low adhesion the cutting edge keeps its form longer, which supports consistent dimensional results and reduces rework. Where finishing quality matters, the combination of geometry and material promotes improved surface integrity on soft and gummy alloys.

Secure clamping and repeatable accuracy for production setups

The square 90° plate form offers secure seating in standard milling pockets, while the specified tolerance class K ensures repeatable positioning across insert changes. The 11° relief angle reduces flank contact and helps to avoid rubbing, which lowers heat generation at the cutting edge and preserves sharpness. For workshops managing frequent index changes, this leads to shorter setup influence on process capability and a more stable tool life expectation. The Walter N‑series background ensures the insert integrates smoothly into established cutter bodies that accept square‑form indexable plates.

Easier process integration and improved productivity

Selecting a grade like WAK15 for non‑ferrous workpieces simplifies tool inventory and streamlines process planning: one insert type covers a broad range of aluminium and related alloys. The uncoated design reduces the risk of material adhesion during light interrupted cuts and is especially effective in achieving high surface finish with conservative feeds and speeds. For manufacturers seeking higher throughput, the insert supports productive machining by keeping changeover predictable and enabling sustained cutting parameters. Technical consultation from Metav Werkzeuge can aid in matching cutter geometry and grade to the specific alloy and operation to maximise productivity.

FAQ

Is this insert suitable for all aluminium alloys? The SPKT1204AZN WAK15 is optimised for a wide range of aluminium and other non‑ferrous alloys; the WAK15 grade and sharp geometry reduce adhesion and improve chip control across typical aluminium variants.

Will the square 90° form fit standard cutter bodies? The square 90° shape and tolerance class K are intended for standard indexable milling pockets; however, verification of seat type and clamping method in the chosen cutter body is recommended before assembly.

Can the insert be used for finishing passes to improve surface quality? Yes, the uncoated carbide grade and reduced rubbing from the 11° relief angle make this insert well suited to finishing and semi‑finishing operations on aluminium where surface integrity is important.

What are the physical dimensions and the SKU for ordering? Plate size 12, plate thickness 04, relief angle 11°, form Quadrat 90°; SKU SPKT1204AZN-WAK15-WALTER.
