WCGT040202‑X5 WAK15 indexable insert — Trigon 80° for aluminium machining by Walter Tools

A robust indexable insert designed for drilling and boring operations in aluminium and non‑ferrous materials, combining the Walter N‑grade concept with a chipbreaker tailored for controlled swarf evacuation

• WAK15 uncoated carbide for aluminium
• Trigon 80° form for secure seating
• 0.2 mm corner radius for fine finishes
• Chipbreaker X5 for controlled aluminium chips

High efficiency for non‑ferrous production

The WAK15 grade is an uncoated carbide formulation optimised for machining aluminium, offering low adhesion and reduced tendency for built‑up edge. The insert’s geometry provides a cutting face that supports stable chip control and lower friction, which translates into longer tool life and fewer interruptions for cleaning or rework. For manufacturers focused on repeatability and throughput, this means fewer stoppages and a more consistent process window when producing components from aluminium and similar non‑ferrous alloys.

Precision seating and surface quality

The Trigon 80° plate form with a 0.2 mm corner radius ensures a stable tool fit and predictable engagement at the cutting edge. The modest corner radius helps to balance edge strength with the ability to achieve a fine surface finish, particularly on thin‑walled or delicate workpieces. Combined with the specified clearance geometry, the insert reduces chatter risk and supports reliable dimensional control in series production, benefitting job shops and OEM supply chains that demand consistent part quality.

Controlled swarf and process reliability

The chipbreaker X5 is configured to break and evacuate aluminium swarf effectively, reducing clogging at the cutting zone and helping maintain cutting temperatures within acceptable limits. The relief geometry (7° nominal) supports smooth entry and exit, limiting edge rubbing and heat build‑up. These characteristics contribute directly to high productivity by enabling longer uninterrupted cuts and reducing the frequency of insert changes or secondary finishing operations.

Application scope and practical guidance

Designed under the Walter N‑grade system, the insert is suitable for a range of non‑ferrous work, mainly aluminium, copper and brass alloys. Its uncoated nature is deliberately chosen to avoid coating‑related adhesion on softer metals; this promotes cleaner chips and lowers the risk of material sticking to the edge. For best results, combine this insert with appropriate feed rates and coolant strategies for aluminium machining, ensuring stable clamping and correct toolholder alignment to exploit the insert’s advantages fully.

FAQ

Is this insert suitable for aluminium machining?
Yes. The WCGT040202‑X5 WAK15 insert is specifically designed for aluminium and other non‑ferrous metals, using the WAK15 uncoated carbide grade to reduce material adhesion.

Does the insert have a coating?
No. The insert uses an uncoated carbide grade (WAK15), which is advantageous for machining soft, adhesive metals such as aluminium.

What benefit does the Trigon 80° form provide?
The Trigon 80° geometry offers a secure seating and cut engagement that improves stability and repeatability during drilling and boring operations.

How does the chipbreaker X5 improve production?
The chipbreaker X5 breaks and directs aluminium swarf for reliable evacuation, reducing clogging and helping to maintain consistent cutting conditions.

Which series and system does this insert belong to?
This insert is part of the Walter N‑Sortensystem, developed for non‑ferrous applications and tailored cutting behaviour.
