OPHN0504ZZN-A57 WAK15 milling insert (octagonal, 11° free angle) — Walter Tools

The OPHN0504ZZN-A57 WAK15 is an octagonal milling insert engineered for efficient machining of aluminium and other non‑ferrous metals, suited to high‑productivity finishing and semi‑finishing operations

• Optimised for aluminium and non‑ferrous metals
• Octagonal design for eight cutting edges
• A57 chipbreaker reduces material adhesion
• 11° free angle for improved surface quality

Improved aluminium machining with a sharp, low‑adhesion grade

The WAK15 grade is an uncoated carbide developed for non‑ferrous materials, delivering a sharp cutting edge and consistent chip control. Combined with the A57 chipbreaker, the geometry reduces material adhesion and built‑up edge, which is especially relevant when working with sticky alloys such as aluminium and similar non‑ferrous metals. This leads to longer uninterrupted runs, fewer regrinds and a measurable uplift in process throughput while maintaining a stable cutting action.

Consistent surface finish thanks to optimised geometry and clearance

An 11° free angle and the insert’s precise geometry contribute directly to a smoother surface finish and reduced burr formation. The tolerance class H ensures repeatable positioning in the cutter body, which supports stable toolpaths and predictable component quality. These attributes make the insert appropriate where surface integrity and dimensional consistency are required, for example in finishing faces or lightweight structural components.

Economy through multiple edges and simple indexing

The octagonal format provides eight usable cutting edges per insert, reducing tool change frequency and the cost per edge. With a compact profile (size 05, thickness 04) and robust form, the insert offers a balance between edge strength and accessibility in tight pockets. The combination of shape and grade also simplifies inventory management: fewer unique items are needed to cover a wide range of non‑ferrous applications, while downtimes for tool replacement are minimised.

Material range and practical application notes

Designed within the Walter N‑Sortensystem, this insert is tailored for aluminium and similar non‑ferrous alloys such as copper and brass. The uncoated carbide substrate performs best with a suitably sharp geometry and recommended cutting parameters to avoid smearing; coolant strategy and feed choice should be matched to alloy and operation. For end‑users seeking consistent chip evacuation and clean edges in high‑speed milling of non‑ferrous components, this insert presents a pragmatic solution.

FAQ

What materials is this insert designed for?
The OPHN0504ZZN-A57 WAK15 insert is intended for aluminium and other non‑ferrous metals; the WAK15 grade and A57 chipbreaker provide low adhesion and controlled chip formation.

How many cutting edges does the octagonal insert provide?
The octagonal design offers eight usable cutting edges, which extends tool life per insert and reduces the frequency of index changes.

What does the 11° free angle affect in machining?
An 11° free angle improves clearance behind the cutting edge, reducing friction and supporting a finer surface finish when milling non‑ferrous components.

Is the grade coated or uncoated and why does that matter?
WAK15 is an uncoated carbide grade optimised for sharp edges and non‑ferrous alloys; the lack of coating helps avoid material smearing and built‑up edge with soft, sticky materials.
