BCHT120408R-K85 WXN15 milling insert (Parallelogram 75°) – Walter Tools

BCHT120408R-K85 WXN15 is a milling insert engineered for high‑efficiency machining of non‑ferrous metals, offering a sharp uncoated carbide grade for reduced material adhesion.

• Optimised for non‑ferrous metals
• Sharp uncoated carbide grade WXN15
• K85 chipbreaker for controlled chips
• Parallelogram 75° geometry for versatility

Reliable performance on non‑ferrous alloys

The WXN15 grade is an uncoated carbide formulation developed for machining aluminium, copper and brass; it delivers a consistently sharp cutting edge that reduces built‑up edge and enhances surface finish. With the insert’s geometry tuned for aluminium alloys, the result is improved productivity through fewer interruptions for chip clearing and more predictable tool life. The combination of a sharp grade and dedicated chip control is particularly suited to light‑to‑medium milling operations where surface quality and low adhesion are priorities.

Geometry and chip control that support productivity

The parallelogram 75° form combined with the K85 chipbreaker and a 0.8 mm corner radius provides a balance between edge strength and fine finishing capability. The listed 7° relief angle reduces rubbing on the machined surface while maintaining sufficient clearance during engagement. These features assist in producing uniform chips and reducing vibration, which in turn helps to maintain consistent tolerances and improves cycle reliability in industrial milling applications.

Practical application and mounting guidance

Designed within the Walter N‑Series, the insert is suitable for cutters accepting the BCHT form and the specified thickness code. Its uncoated nature makes it the preferred choice for sharp, adhesion‑sensitive operations on the ISO group N materials. For best results, select feed and speed parameters that limit heat build‑up and favour continuous chip formation; the insert’s chipbreaker assists in breaking long chips typical of soft, ductile alloys and supports safer handling at the tool holder.

Consistency and process security in production

As part of a proven tooling series by Walter Tools, this insert contributes to predictable machining results and stable chip formation across batch production. The standardised geometry and grade pairing simplify tool selection and help to maintain repeatable surface quality from one batch to the next. When paired with appropriately rated cutters, the assembly supports efficient throughput and reduces the risk of unexpected downtime due to chip‑related interruptions.

FAQ

What materials is this insert intended for?
The BCHT120408R‑K85 WXN15 insert is intended for ISO group N materials, specifically non‑ferrous metals such as aluminium, copper and brass.

Is the cutting material coated?
The WXN15 grade used in this insert is an uncoated carbide designed for sharp cutting and reduced adhesion in soft, ductile materials.

Which chip behaviour can be expected with the K85 chipbreaker?
The K85 chipbreaker promotes controlled chip formation, reducing long, stringy chips and aiding safe chip evacuation during continuous milling of non‑ferrous alloys.

Can this insert be used for roughing and finishing?
With its 0.8 mm corner radius and sharp grade, the insert suits fine finishing and medium‑duty operations; selection of specific feeds and speeds should reflect the desired balance between surface finish and metal removal rate.
