LNHU090404R-L85T WXN15 milling insert — Walter Tools — for non‑ferrous metals, 0° negative rake

The LNHU090404R-L85T WXN15 is a rectangular milling insert designed for sharp, uncoated performance when machining non‑ferrous materials such as aluminium and brass.

• Uncoated solid carbide grade WXN15
• Dedicated L85T chipbreaker for NE‑metals
• Rectangular geometry with 0.4 mm radius
• Negative rake 0° for stable cutting

Consistent chip control for non‑ferrous machining

The combination of a sharp uncoated carbide grade and the L85T chipbreaker delivers predictable chip formation when working with aluminium, copper or brass. This results in fewer built‑up edge occurrences and a cleaner surface finish, which reduces secondary operations. The geometry and cutting edge preparation are optimised for reaming off thin materials without smeared chips; as a consequence, production processes run with fewer interruptions and tool life becomes more reproducible.

Designed for secure, repeatable results and easy tool management

Built as part of the Walter N‑Sortensystem, this insert provides a well‑defined seating and tolerance class H, supporting repeatable clamping and indexing. The negative rake of 0° enhances edge strength for interrupted cuts and keeps deflection low in light‑to‑medium milling tasks. Together with the compact rectangular form and a 0.4 mm corner radius, the geometry balances edge robustness with the fine finishing capability needed in many non‑ferrous applications.

Productivity gains through simplified tool choice and integration

Using an uncoated, sharp‑edge grade reduces the need for complex coatings when machining NE‑metals, lowering the risk of built‑up edge and minimising thermal adhesion. The insert’s clear designation and compatibility with standard holders make tool changeover straightforward; fewer variations in tooling mean quicker setup times and reduced inventory complexity. For workshops seeking reliable productivity in non‑ferrous milling, this plate supports efficient throughput while maintaining surface quality.

FAQ

Which materials is this insert suitable for?
The LNHU090404R-L85T WXN15 is optimised for non‑ferrous metals such as aluminium, copper and brass and is specified for group N materials.

What does the WXN15 grade indicate?
WXN15 denotes an uncoated Walter carbide grade developed for sharp cutting in NE‑metals; it prioritises low adhesion and consistent edge retention.

How does the 0° negative rake affect machining?
A 0° negative rake increases edge strength and stability during milling; with the L85T chipbreaker it supports controlled chips and reduces the risk of edge chipping.

Is the insert compatible with standard rectangular tool holders?
Yes, the rectangular form and tolerance class H ensure reliable seating in compatible holders designed for the Walter N‑Sortensystem.
