LNHU130608R-L55T WAK15 indexable milling insert — negative 0° relief, L55T chipbreaker — Walter Tools

The LNHU130608R-L55T WAK15 is an indexable milling insert designed for high‑quality machining of aluminium and other non‑ferrous metals, combining a sharp cutting geometry with a chipbreaker optimised to prevent material adhesion

• Uncoated carbide grade WAK15 for non‑ferrous metals
• L55T chipbreaker reduces built‑up edge
• Negative 0° relief for stable engagement
• Rectangular 13 mm insert, 0.8 mm corner radius

Faster, cleaner aluminium machining through edge geometry

The combination of the WAK15 uncoated carbide grade and a finely tuned cutting geometry ensures efficient removal of soft, ductile materials such as aluminium and other non‑ferrous metals. The uncoated carbide offers a very sharp edge that reduces cutting forces and helps to avoid torn surfaces; the result is improved surface finish and fewer secondary operations. In practical terms, this means shorter cycle times and reduced rework when machining thin‑walled components or profiles where adhesion would otherwise degrade results.

Stable engagement with negative relief for reliable productivity

A negative 0° relief provides a robust contact zone between the insert and the toolholder, increasing stability during interrupted cuts and plunge operations. This geometry supports secure clamping and helps maintain a consistent cutting edge under moderate radial loads, translating into predictable tool life and fewer insert changes. For production environments where repeatability matters, the stable engagement reduces vibration and contributes to constant part tolerances across batches.

Chip control designed to prevent material build‑up

The L55T chipbreaker is engineered to direct chips away from the cutting zone and to minimise built‑up edge when working with sticky materials. Good chip control reduces the risk of smearing and sticking on the flank face, which in turn protects the cutting edge and preserves dimensional accuracy. For users transitioning from conventional tools, this feature helps to maintain process reliability while preserving surface integrity on delicate aluminium alloys.

Practical specification and compatibility for workshop selection

The insert is supplied in a rectangular form with a nominal size of 13 mm and a corner radius of 0.8 mm, thickness code 06, and tolerance class H. These dimensions make it suitable for a range of common toolholders used in face and shoulder milling of non‑ferrous components. The product belongs to the Walter N‑series, which is noted for consistent manufacturing quality; matching toolholders to the insert geometry ensures optimal clamping and cutting performance.

FAQ

Which materials are suitable for this insert?
The LNHU130608R-L55T WAK15 insert from Walter Tools is intended for aluminium and other non‑ferrous metals in accordance with ISO 513 classifications.

Is the cutting grade coated or uncoated?
The WAK15 grade is uncoated carbide, selected to provide a very sharp edge and minimise adhesion when machining non‑ferrous materials.

What is the relief or clearance angle of the insert?
This insert has a 0° negative relief, offering increased stability and secure engagement for milling operations with moderate radial loads.

What are the insert dimensions and form?
The insert is rectangular, nominal size 13, thickness code 06, with a 0.8 mm corner radius and tolerance class H.

How does the L55T chipbreaker help in practice?
The L55T chipbreaker guides chips away from the cutting zone and reduces built‑up edge, which preserves the cutting edge and improves surface finish when machining aluminium alloys.
