XNHF070508-D67 WAK15 milling indexable insert — WAK15 grade for aluminium machining, Walter Tools

A XNHF070508-D67 WAK15 milling insert designed for high‑performance machining of aluminium and other non‑ferrous metals, optimised for precise finishing and reliable chip control.

• WAK15 uncoated carbide for aluminium machining
• Fine 0.8 mm corner radius for improved surface finish
• Chipbreaker D67 for controlled swarf evacuation
• 0° negative free angle for stable cutting action

Precision surface results for aluminium and non‑ferrous metals

The insert combines a sharp, uncoated carbide grade with an edge geometry tailored to non‑ferrous materials, delivering reproducible surface quality when milling aluminium and similar alloys. The WAK15 grade is specifically designed to avoid material adhesion and to maintain a sharp cutting edge for long intervals, which translates into fewer interruptions and more consistent part tolerances. For users less familiar with carbide grades: uncoated grades offer excellent edge definition and are often preferred where high thermal conductivity of the workpiece and low cutting forces reduce the need for coatings.

Geometry engineered for stable cutting and reliable chip control

The cutting geometry features a 0° negative free angle and a chipbreaker D67, which together balance cutting stability and swarf management. A negative free angle increases edge strength and reduces vibration under interrupted cuts, while the D67 chipbreaker directs chips away from the cutting zone, improving tool life and machine uptime. The 0.8 mm corner radius helps to distribute cutting forces across the edge, reducing micro‑chipping and supporting a finer surface finish on demanding components.

Practical deployment and tooling recommendations

When integrating this insert into a production cell, pair it with a rigid, high‑precision milling cutter and appropriate feed rates for aluminium alloys to exploit the Walter N‑Grade system benefits. The insert’s dimensions and tolerance class support repeatable mounting and predictable performance. For finishing passes, the fine corner radius and sharp grade favour lower cutting forces and improved aesthetics; for more aggressive stock removal, consider adjusting depth of cut and feed to preserve edge life while maintaining throughput.

FAQ

What materials is this insert suited to?
The XNHF070508‑D67 WAK15 insert is intended for aluminium and other non‑ferrous metals, as the WAK15 grade and geometry minimise material adhesion and promote clean chip formation.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius spreads cutting forces over a larger edge, enhancing edge strength and improving surface finish while reducing the risk of small edge chipping during finishing operations.

What is the role of the D67 chipbreaker?
The D67 chipbreaker controls swarf shape and evacuation, reducing recutting and helping to maintain stable cutting conditions, which supports higher productivity and longer tool life.

Is the insert coated or uncoated, and why does that matter?
This insert uses an uncoated carbide grade (WAK15); uncoated grades are chosen for their sharp edges and low tendency to pick up non‑ferrous material, making them well suited to aluminium machining.

Which tolerance class is specified and why is it important?
The insert is supplied in tolerance class H, ensuring consistent dimensions for repeatable mounting and accurate machining results.
