LNHX130608R-L55T WAK15 milling indexable insert for aluminium and non‑ferrous metals (Walter Tools) — 0° negative clearance, L55T chipbreaker

The LNHX130608R-L55T WAK15 is a rectangular milling insert engineered for high‑efficiency machining of aluminium and other non‑ferrous materials, offering robust performance and consistent chip formation in profiling and face‑milling applications.

• Optimised chip control L55T
• For aluminium and non‑ferrous metals
• Negative 0° clearance geometry
• Rectangle form with 0.8 mm corner radius

Consistent aluminium machining with dedicated carbide grade

The insert is built on the WAK15 uncoated carbide grade, specifically developed for non‑ferrous metals. This composition delivers a sharp, wear‑resistant cutting edge while limiting built‑up edge during aluminium machining. The integrated L55T chipbreaker improves chip evacuation and reduces the risk of material adhesion, which supports higher feed rates and stable cycle times. As a result, productivity rises without compromising component quality.

Stable process and improved surface quality

A negative 0° clearance and the rectangular geometry ensure a secure seat in the cutter body and predictable cutting forces. The 0.8 mm corner radius balances edge strength with the ability to produce good surface finishes on soft alloys. Together these characteristics promote repeatable results, lower scrap rates and longer tool life in medium‑ to high‑volume production. The insert’s geometry is optimised for controlled chip formation, which contributes directly to consistent surface quality.

Simple integration and application scope

Designed for use in the Walter N‑Series, the insert is suitable for profiling, slotting and light face milling in aluminium and other ISO group N materials. The execution code X denotes the insert’s negative geometry, compatible with a wide range of cutter bodies that accept rectangular plates. The tolerance class H supports high repeatability in indexing and re‑clamping, helping to reduce downtime and set‑up effort on automated machines and manual toolholders alike.

FAQ

Is this insert suitable for high‑feed milling of aluminium?
The LNHX130608R-L55T WAK15 insert, with its L55T chipbreaker and uncoated WAK15 grade, is designed to support higher feeds in aluminium machining while maintaining chip control.

Can the insert be used for other non‑ferrous metals?
Yes, the insert is specified for ISO 513 group N, which covers aluminium, copper, brass and similar non‑ferrous materials.

What does the negative 0° clearance mean for cutter selection?
Negative 0° clearance indicates a robust geometry requiring compatible cutter bodies that are designed for negative inserts; this increases edge strength and stability during interrupted cuts.

How does the 0.8 mm corner radius affect surface finish?
A 0.8 mm corner radius provides a compromise between edge strength and finishing capability, giving good surface quality on softer alloys while protecting the cutting edge.

What does tolerance class H imply for repeatability?
Tolerance class H denotes tight manufacturing tolerances for the insert, supporting consistent seating and repeatable machining results after indexing.
