CNMQ080508-A57T WAK15 – Milling indexable insert for aluminium machining by Walter Tools

The CNMQ080508-A57T WAK15 is a rhombic 80° milling insert engineered for high‑performance machining of aluminium and other non‑ferrous metals, featuring an A57T chipbreaker and an uncoated WAK15 grade.

• Uncoated WAK15 grade for soft metals
• Rhombic 80° insert form
• 0.8 mm corner radius for edge strength
• Optimised chipbreaker A57T for aluminium

Consistent aluminium removal with low built‑up edge

The insert delivers reliable material removal in aluminium applications thanks to the uncoated WAK15 carbide composition and a geometry tailored to non‑ferrous metals. The combination of a sharp cutting edge and the A57T chipbreaker reduces material adhesion, which minimises interruptions for manual cleaning and improves process stability. For production environments, this results in steady cycle times and a reduced need for secondary finishing, translating into measurable efficiency gains.

Geometry that balances edge life and surface quality

A rhombic 80° outline paired with a 0.8 mm corner radius provides a robust cutting edge that resists premature chipping while still enabling fine surface results on aluminium alloys. The 0° negative clearance supports a secure seating in toolholders and helps maintain consistent cutting forces during shoulder milling and light face milling. These geometric choices offer a balance between tool life and the finish quality expected in high‑volume machining.

Series and grade for predictable performance

As part of the Walter N‑grade system, the insert’s WAK15 designation specifies an uncoated carbide suited for aluminium and other non‑ferrous materials according to ISO 513 group N. The design and material selection aim for stable chip formation and repeatable performance, which supports process planning and tool‑change scheduling in manufacturing. The tolerance class M and execution Q ensure dimensional reliability for predictable mounting and indexing.

Integration into machining strategies and benefits at scale

When integrated into a systematic tooling strategy, the insert helps reduce overall machining costs by lowering scrap rates and minimising rework. The A57T chipbreaker assists in generating short, controllable chips that improve coolant interaction and reduce the risk of chip entanglement. For workshops processing large batches of aluminium components, this means fewer stoppages and a higher overall equipment effectiveness (OEE).

FAQ

What materials is this insert optimised for?
The CNMQ080508-A57T WAK15 insert is optimised for aluminium and other non‑ferrous metals (ISO group N), using an uncoated WAK15 carbide to reduce material adhesion.

How does the A57T chipbreaker affect machining?
The A57T chipbreaker on this milling insert promotes short, controllable chips in aluminium machining, improving chip evacuation and reducing the risk of re‑cutting.

What does the 0° negative free angle mean for toolholding?
A 0° negative free angle ensures a secure seating in compatible toolholders and maintains stable cutting forces during shoulder and face milling operations.

Can this insert achieve good surface finishes on aluminium?
Yes; the rhombic 80° form combined with a 0.8 mm corner radius balances edge strength and surface quality for high‑finish aluminium machining when cutting parameters are set appropriately.

Is the CNMQ080508-A57T WAK15 suitable for automated high‑volume production?
The insert’s grade and chipbreaker are designed for consistent chip control and tool life, making it suitable for repeatable, high‑volume aluminium production runs.
