OPHX0504ZZR-A57 WAK15 milling insert — uncoated carbide for aluminium and non‑ferrous metals | Walter Tools

The OPHX0504ZZR-A57 WAK15 is an octagonal milling insert designed for efficient, low‑adhesion machining of aluminium and other non‑ferrous metals within modular Walter N‑system toolholders.

• Uncoated carbide WAK15 for aluminium
• Octagonal geometry for versatile orientation
• 11° relief angle for sharp cutting action
• Chipbreaker A57 for improved chip control

Faster, cleaner aluminium machining with sharp uncoated carbide

The combination of the WAK15 grade — an uncoated carbide specifically developed for N‑materials — and a reamed cutting geometry delivers low friction and reduced material adhesion during aluminium cutting. This minimises built‑up edge and the risk of smearing on the workpiece, which in turn supports higher effective cutting speeds and more consistent part quality. Where softer, ductile non‑ferrous metals are in use, this insert’s geometry reduces the need for excessive lubricant, offering a pragmatic balance between productivity and process cleanliness.

Consistent surface finish and dependable chip control

The octagonal shape together with the 11° relief creates multiple indexed cutting edges and a reliable contact angle for light to medium finishing passes. The integrated chipbreaker A57 promotes predictable chip formation and evacuation, which reduces the likelihood of re‑cutting or surface blemishes. With a tolerance class H, the insert supports repeatable positioning and minimal run‑out in the tool body, contributing to reproducible surface integrity and reduced rework in series production.

Simple integration into Walter N‑system applications

Designed for the Walter N‑Sortensystem, the insert fits toolholders configured for the OPHX geometry and is produced in the compact size 05 with thickness 04, allowing compact cutter assemblies and high index counts per cutter. For process planning, the insert is coded for N‑materials and is therefore recommended for aluminium and other non‑ferrous alloys according to ISO 513. For machining parameter recommendations or holder compatibility, Metav Werkzeuge can provide cutting data and holder suggestions tailored to the workpiece alloy and required surface finish.

Durable choice for specialised non‑ferrous production

Backed by the Walter Tools heritage in precision cutting, this insert is intended for production environments demanding consistent results and reduced cycle interruption. The uncoated carbide base yields excellent edge clarity for soft metals, while the geometry and chip control features reduce operator intervention. In short runs or in larger batches where aluminium components must meet tight tolerances, the insert offers a focused solution that supports both productivity and process reliability.
