BCHT120440L-K85 WXN15 Milling indexable insert — Parallelogram 75°, uncoated carbide, Walter Tools

BCHT120440L-K85 WXN15 is a precision milling insert designed for productive machining of non‑ferrous metals in a wide range of milling applications.

Sharp uncoated carbide grade WXN15 Parallelogram 75° shape for versatile milling 7° relief angle to reduce rubbing 4 corner radius for consistent surface quality

Consistent performance for non‑ferrous machining

The insert combines the WXN15 uncoated carbide grade with a geometry optimised for N‑materials, making it particularly suitable for aluminium, copper and brass. The sharp cutting edge and low‑adhesion surface behaviour reduce built‑up edge and minimise rework, delivering more predictable part quality. Because the grade is uncoated, the cutting edge remains extremely sharp, which benefits finishes and burr formation when working with soft, gummy alloys. The result is a balance of productivity and dimensional stability that supports continuous production runs.

Geometry that improves chip control and surface finish

A parallelogram 75° form and the K85 chipbreaker function together to direct chips away from the cutting zone and reduce recutting, which helps maintain tool life and part integrity. The insert’s 4 corner radius supports a steady surface finish while allowing slight engagement angles that avoid aggressive material tearing. The 7° relief angle minimises flank rubbing, lowering cutting forces during entry and exit. These geometric choices are especially effective for sharp, uncoated applications where chip evacuation and coolant access are decisive for process reliability.

Application guidance and process advantages

Belonging to the Walter N‑Sortensystem, the insert is tailored for high reproducibility in the machining of non‑ferrous metals and for operators seeking predictable edge behaviour. Tolerance class and execution ensure consistent seating and stable cutting conditions in indexable milling holders. The combination of chip control and sharp grade translates into reduced secondary operations and better surface quality, supporting cost‑efficient production. For parameter selection and optimisation, consult process data to align feed and speed with the chosen holder and workpiece material, ensuring the full potential of the plate is realised.

FAQ

What materials is this insert suitable for? The BCHT120440L-K85 WXN15 insert is designed primarily for non‑ferrous metals such as aluminium, copper and brass, reflecting the WXN15 grade and the N application group.

How does the K85 chipbreaker affect machining? The K85 chipbreaker promotes controlled chip formation and evacuation; with the sharp WXN15 edge it reduces material adhesion and improves surface finish during milling.

What does the parallelogram 75° shape mean for application? A parallelogram 75° form provides flexible approach angles for a variety of milling strategies, enabling stable entry and exit conditions and effective chip flow with the K85 geometry.

Is the grade coated or uncoated, and why does that matter? The insert is an uncoated cemented carbide (WXN15), which keeps the cutting edge very sharp—beneficial for soft, ductile non‑ferrous alloys where minimal rubbing and low built‑up edge are essential.

Which series does this insert belong to and what does that imply? It belongs to the Walter N‑Sortensystem, indicating a family of grades and geometries optimised for non‑ferrous machining with consistent performance and predictable edge behaviour.
