WOMX080408-D57 WAK15 drill/bore indexable insert – Walter Tools

WOMX080408-D57 WAK15 is an indexable cutting insert for drilling and bore enlargement in aluminium and other non‑ferrous metals

• Uncoated carbide grade WAK15 for N‑materials
• Trigon 80° geometry for stable contact
• 0.8 mm corner radius for edge strength
• Chipbreaker D57 for optimised chip control

Precision for non‑ferrous machining and production reliability

The Trigon 80° geometry and the WAK15 carbide grade are configured for machining aluminium and non‑ferrous metals, delivering a balance between sharp cutting action and sufficient edge robustness. In practice this means improved hole quality and repeatable bore diameters when processing softer alloys; the geometry reduces axial forces while the chosen cutting material maintains form at typical cutting parameters for these groups. The result is a more predictable process and fewer reworks in series production.

Geometry and chip control that reduce machining interruptions

A controlled chipflow is essential for efficient drilling and boring. The combination of the D57 chipbreaker and the trigon form improves chip breaking and evacuation in circular bores, decreasing the risk of built‑up edge and machine stoppages. With a corner radius of 0.8 mm, the insert keeps a durable cutting edge that tolerates intermittent contact and contributes to consistent surface finishes. These attributes support longer uninterrupted runs and higher machine availability.

Material choice explained: uncoated carbide for non‑ferrous applications

The uncoated carbide WAK15 grade is specifically intended for N‑materials (non‑ferrous), where coatings can sometimes promote material adhesion. An uncoated substrate provides a very sharp primary edge and low friction at the contact zone, reducing the tendency for aluminium to weld onto the insert. For workshops aiming for clean holes and minimal burr formation in light alloys, this material choice combines cutting efficiency with simpler dressing and handling routines.

Practical advantages and suitable applications

Designed within the Walter N‑system, this insert suits a range of drilling and bore‑enlarging tasks in light‑metal components, fixtures and assemblies. The Trigon 80° form supports stable tool engagement in guided operations, while the D57 chip control helps in semi‑deep bores where evacuation paths are limited. For production environments seeking predictable cycle times, the insert contributes to improved first‑pass yield and easier process documentation thanks to its standardised design features.

FAQ

What materials is this insert suitable for?
This WOMX080408-D57 WAK15 insert is designed for aluminium and other non‑ferrous metals, specified as ISO group N.

Is the cutting grade coated or uncoated?
The WAK15 grade is an uncoated carbide chosen to provide a sharp edge and reduce material adhesion when machining light alloys.

How does the Trigon 80° shape affect cutting performance?
The Trigon 80° form improves contact stability during drilling and bore enlargement, lowering axial loads and supporting consistent hole geometry.

What benefit does the D57 chipbreaker provide?
The D57 chipbreaker promotes controlled chip formation and evacuation, which reduces the likelihood of clogging and improves process reliability in bores.

Can the insert be used for finishing operations?
While optimised for drilling and bore enlargement in non‑ferrous materials, the design supports good surface quality; however, finishing requirements depend on the specific process and toolholder arrangement.
