BCHT120420R-K85 WXN15 milling insert — sharp uncoated grade for non‑ferrous metals (Parallelogram 75°, 7° clearance) by Walter Tools

The BCHT120420R-K85 WXN15 is a parallelogram milling insert designed for sharp, uncoated cutting of non‑ferrous materials such as aluminium, copper or brass, offering stable chip formation and consistent edge life in the Walter N‑series.

• Walter N‑series uncoated carbide WXN15
• Optimised for non‑ferrous metals machining
• Parallelogram 75° geometry for axial stability
• K85 chipbreaker for controlled chips
• 7° clearance angle with 2 mm corner radius

Faster, cleaner results with a sharp uncoated grade

The uncoated WXN15 grade is formulated for low‑adhesion cutting in non‑ferrous alloys, delivering a sharp cutting edge that reduces material build‑up and improves surface finish. The combination of an uncoated cemented carbide substrate and the K85 chipbreaker supports consistent chip segmentation, which reduces rework and machine downtime. This is particularly important when working with soft, ductile materials where chip control and prevention of material adhesion are decisive for process stability.

Geometry and mechanics that improve productivity

The parallelogram 75° plate form provides secure axial engagement and is well suited for versatile milling setups; the 7° clearance reduces rubbing while the 2 mm corner radius balances edge strength and finish quality. These design choices enable higher feed rates and predictable tool life when milling thin‑walled or delicate components. In practice, the geometry translates into fewer interruptions for tool changes and a more continuous production flow, which benefits batch and serial machining alike.

Application focus and practical advantages on the shop floor

Designed within the Walter N‑Sortensystem, this insert targets NE materials and is recommended where sharp, uncoated performance is required. The insert supports machining of aluminium, copper or brass with improved surface results and reduced tendency for built‑up edge. Where process reliability and repeatable quality are priorities, the combination of the WXN15 grade and the insert’s chipbreaker yields measurable improvements in cycle times and part consistency, making it a practical choice for manufacturers handling non‑ferrous components.
