Taking advantage of the WXN15 uncoated cemented‑carbide grade together with the K85 chipbreaker and a precise parallelogram 75° geometry results in clean, low‑adhesion cuts in non‑ferrous metals and predictable tool life; order the insert directly via Metav Werkzeuge or ask the consultants for application advice.

BCGT090304R-K85 WXN15 – Indexable milling insert for non‑ferrous metals, K85 chipbreaker · Walter Tools

A BCGT090304R-K85 WXN15 indexable insert engineered for sharp, low‑adhesion milling of aluminium, copper and brass.

• Uncoated cemented carbide grade WXN15
• K85 chipbreaker for sharp cutting
• Parallelogram 75° insert geometry
• 7° clearance angle for smooth cuts

High efficiency in non‑ferrous machining

The WXN15 grade is an uncoated cemented‑carbide formulation optimised for the ISO group N (non‑ferrous metals). Its sharp cutting edge geometry reduces material adhesion and minimises built‑up edge, which directly improves surface finish and reduces secondary deburring. For operations on aluminium, copper and brass, the combination of a fine carbide matrix and a low‑adhesion geometry delivers repeatable results and helps maintain steady cycle times in production runs.

Geometry and chip control for reliable process results

A K85 chipbreaker is designed to support sharp‑edge machining by promoting controlled chip formation and evacuation. The parallelogram 75° insert shape provides robust cutting engagement and favourable rake control, while the 7° relief angle reduces rubbing on the flank and helps to maintain consistent cutting forces. The small 0.4 mm corner radius gives a balance between edge strength and fine surface finish, making the insert suited to finishing or light roughing where chip control and dimensional stability matter.

Practical application and workshop benefits

As an indexable milling insert in the Walter N‑series, this component allows quick index changes and economical reuse of the insert body, reducing overall tooling cost per workpiece. The insert size and thickness are matched to standard toolholders for straightforward integration into existing tool chains. For shops machining non‑ferrous components, the insert reduces cycle time variability and supports a higher first‑pass yield thanks to predictable chip behaviour and lower risk of material build‑up on the cutting edge.

FAQ

What materials is this insert suitable for?
The BCGT090304R-K85 WXN15 insert is intended for non‑ferrous metals, notably aluminium, copper and brass, matching the ISO N group specified for the WXN15 grade.

Is the cutting grade coated or uncoated?
The WXN15 grade is uncoated cemented carbide, chosen to provide a very sharp cutting edge and to avoid coating‑related edge rounding that can increase adhesion on soft, non‑ferrous materials.

How does the K85 chipbreaker affect cutting performance?
The K85 chipbreaker promotes controlled chip formation with sharp edges, improving evacuation and reducing material build‑up on the cutting edge, which in turn helps to sustain surface quality and tool life.

Which geometry features contribute to surface finish stability?
The parallelogram 75° shape combined with a 7° relief angle and a 0.4 mm corner radius reduces rubbing and vibration, supporting consistent finishes and dimensional repeatability in milling operations.
