OPHX0504ZZN-A57 WAK15 — Walter Tools milling indexable insert, octagonal, 11° clearance

OPHX0504ZZN-A57 WAK15 is a specialised milling insert for high-productivity machining of aluminium and other non-ferrous metals in industrial production environments.

• Uncoated carbide grade WAK15
• Optimised for aluminium and non-ferrous metals
• A57 chipbreaker for consistent chip control
• Octagonal form with 11° clearance

Precision geometry for non‑ferrous machining and improved cycle times

The insert’s geometry, based on the Walter N-grade system, combines a very sharp cutting edge with the A57 chipbreaker, specifically developed for non‑ferrous materials. This combination helps to prevent material adhesion and to produce continuous, controlled chips when cutting aluminium, copper or brass. The result is reduced burr formation and more stable cycle times in series production. The uncoated carbide substrate ensures a crisp edge for high‑quality surface finishes while maintaining economical tool life in softer alloys.

Robust design that simplifies process reliability and tool handling

An octagonal form and a standardised tolerance class H enable flexible indexing and multiple cutting edges per insert, increasing productivity per tool change. The 11° clearance reduces rubbing on the flank face, lowering heat build‑up and wear during high feed operations. These mechanical benefits support consistent dimensional accuracy and repeatability in milling operations, which is especially valuable where component tolerances and surface quality are critical.

Material suitability and system integration for workshop efficiency

The WAK15 grade is an uncoated carbide selected for N‑group materials according to ISO 513; it is thus particularly suited to aluminium and other non‑ferrous metals. Integration into existing milling heads is straightforward thanks to the standardised OPHX geometry and the A57 chipbreaker form. Process engineers will value the clear correspondence between insert geometry and expected machining behaviour, allowing easier selection of cutting speeds and feeds for optimised throughput.

Operational advantages and application scenarios

In finish and semi‑finish milling of non‑ferrous components—such as housing faces, profiles and thin‑walled parts—the insert offers a balance of edge sharpness and chip control that minimises rework. The design reduces the risk of built‑up edge on the tool, contributing to longer intervals between inspections and steady production output. For applications requiring predictable surface quality and efficient material removal, the combination of WAK15 and the A57 chipbreaker delivers tangible gains in process stability.

FAQ

Is this insert suitable for aluminium alloys? Yes. The OPHX0504ZZN-A57 WAK15 insert is specifically designed for aluminium and other non‑ferrous alloys, with the WAK15 grade and A57 chipbreaker providing controlled chip formation.

Can the insert be used for stainless steel or hardened steel? No. The uncoated WAK15 grade and the insert geometry are optimised for non‑ferrous materials and are not intended for stainless or hardened steels.

How many cutting edges are available per insert? The octagonal form allows multiple indexing positions, providing several usable cutting edges before replacement; exact count depends on orientation and holder type.

Does the insert require a coated grade for high‑speed milling? For aluminium machining, the uncoated WAK15 grade often provides superior edge sharpness; coating is not required and may even worsen adhesion in some non‑ferrous applications.

Which system or holders are compatible with the OPHX geometry? The insert conforms to OPHX standard dimensions; it is compatible with milling heads and toolholders that accept OPHX0504 style inserts and support the A57 chipbreaker form.
