ONHF050408-F67 WAK15 milling indexable insert by Walter Tools — octagonal, 0.8 mm corner radius

ONHF050408-F67 WAK15 is a milling indexable insert engineered for high-efficiency machining of aluminium and other non-ferrous materials, providing reliable chip control and multiple cutting edges for uninterrupted production.

*WAK15 uncoated carbide for aluminium machining *Octagonal shape ensures four cutting positions *0.8 mm corner radius for fine detail finishing *F67 chipbreaker for improved chip control

Consistent chip control for aluminium and non‑ferrous materials

The WAK15 grade is an uncoated carbide specifically intended for the reliable machining of aluminium and other non-ferrous metals according to ISO 513. Combined with the F67 chipbreaker, the insert reduces tendency to material adhesion and supports clean chip formation even at higher feeds. This leads to a more consistent surface finish and minimises downtime for manual cleaning or secondary operations, making the insert a pragmatic choice where productivity and process stability are priorities.

Geometry that increases tool life and reduces tooling costs

An octagonal insert shape provides multiple usable cutting edges, enabling rapid indexation and extended service life per insert. The 0.8 mm corner radius offers a balance between strength at the cutting edge and the ability to achieve fine finishing results, while the 0° negative rake contributes to secure seating and predictable cutting behaviour in interrupted or continuous cuts. Together, these design aspects help reduce tooling consumption and improve cost efficiency within standard shop-floor workflows.

Practical shop-floor benefits and application guidance

Belonging to the Walter N‑Sortensystem, this insert benefits from a clear sort allocation and compatibility with established holders. The coded size and thickness designation supports simple inventory management and interchangeability. For tailored cycle times and feed recommendations, machine-specific conditions should be considered; specialist advice is available to match cutting parameters to the spindle power and workpiece setup. The combination of grade and chip geometry is especially suited to series production of aluminium components where repeatability and low burr formation are required.

Quality standards and process reliability

Manufactured to a tolerance class H and supplied in the design variant ONHF050408-F67, the insert offers the precision demanded in industrial environments. Its uncoated nature reduces thermal build-up on soft metals and avoids coating-related adhesion issues, while the F67 chipbreaker helps maintain stable cutting forces. For operations seeking steady, repeatable results from a recognised tooling system, the insert represents a robust technical solution with defined material applicability and clear handling advantages.

FAQ

What materials is this insert suitable for?
The ONHF050408-F67 WAK15 insert is designed primarily for aluminium and other non-ferrous materials as specified by its WAK15 grade and ISO 513 applicability.

How many cutting edges are available per insert?
Due to the octagonal form, the insert allows multiple indexings; the exact number of usable edges depends on machining conditions and edge wear for the ONHF050408-F67 WAK15.

Does the insert have a coating?
The WAK15 grade in this insert is an uncoated carbide variant, chosen to reduce material adhesion when machining soft, sticky metals.

What is the purpose of the F67 chipbreaker?
The F67 chipbreaker on the ONHF050408-F67 WAK15 helps shape chips for safe evacuation and reduces built-up edge, supporting consistent surface quality in series production.

Is this insert compatible with standard Walter tool holders?
Yes, the insert is part of the Walter N‑Sortensystem and is intended for use with holders designed for the ONHF050408-F67 form and size.
