BCHT120440R-K85 WXN15 – Fräswendeschneidplatte for non‑ferrous metals by Walter Tools

BCHT120440R-K85 WXN15 is a milling indexable insert designed for precise, high‑efficiency machining of non‑ferrous materials in industrial milling operations

• Uncoated carbide grade WXN15
• Optimised K85 chipbreaker geometry
• Parallelogram 75° shape for stable seating
• 7° clearance angle for reduced rubbing

Consistent chip control and faster cycle times for non‑ferrous work

The uncoated Walter N‑grade WXN15 is tailored for machining non‑ferrous metals such as aluminium and brass, combining a very sharp cutting edge with a low‑adhesion surface to reduce built‑up edge and minimise material sticking. The K85 chipbreaker channels chips reliably, which shortens tool change cycles and supports higher feed rates. In practice, this means fewer interruptions and improved part throughput on aluminium and copper workpieces, with predictable chip shapes that facilitate safe evacuation from the cutting zone.

Geometry engineered for secure clamping and clean cutting

The parallelogram 75° plate outline gives a compact seating that improves insert stability under milling loads while maintaining access for side cutting operations. A 7° clearance angle reduces flank contact, lowering friction and heat generation at the cutting edge; the result is a cleaner surface finish and less tendency for polishing of the edge on soft metals. The corner radius of 4 provides a balance between edge strength and surface quality, enabling light radius finishes without sacrificing robustness during interrupted cuts.

Practical application guidance and process reliability

This insert is supplied in the Walter N‑Sortensystem and is most effective where sharp, uncoated carbide geometry is required for clean chip detachment in NE‑materials. For slotting, face milling and trochoidal strategies on aluminium alloys, the combination of WXN15 and K85 reduces climb milling adhesions and allows for more aggressive feed per tooth settings. When specifying cutting data, start from manufacturer guidance and gradually increase feed while monitoring surface quality; the machinability gains often deliver shorter cycle times and more consistent tool life compared with generic grades.

FAQ

What materials is this insert intended for?
The BCHT120440R‑K85 WXN15 by Walter Tools is intended for non‑ferrous metals (NE‑materials) such as aluminium, copper and brass, where a sharp, uncoated carbide edge and the K85 chipbreaker improve chip control and surface quality.

Is the grade coated or uncoated and why does that matter?
The insert uses the uncoated WXN15 carbide grade; this uncoated geometry reduces adhesion on soft, ductile metals and preserves the sharpness required for clean cutting in aluminium and similar alloys.

Which machine strategies suit this insert best?
The insert performs well in face milling, slotting and trochoidal milling of non‑ferrous workpieces; using moderated cutting speeds with elevated feed per tooth yields efficient material removal and consistent chip formation with the K85 chipbreaker.

How does the parallelogram 75° shape affect mounting and cutting?
The parallelogram 75° contour provides a compact, stable seating that resists rotation under load and allows access for side cutting operations, improving process reliability for milling tasks on non‑ferrous materials.
