LNHX0904PDR-L55T WAK15 — Milling indexable insert for aluminium and non‑ferrous metals (Rectangular 09, 0° negative) — Walter Tools

A LNHX0904PDR-L55T WAK15 milling indexable insert designed for high‑performance machining of aluminium and other non‑ferrous metals within the Walter N‑series system.

• Uncoated carbide WAK15 for aluminium and NE metals
• Rectangular 09 format with 0° negative rake
• L55T chipbreaker for reliable chip control
• Compatible with Walter N‑series milling system

Faster, cleaner aluminium machining with a grade optimised for non‑ferrous metals

The combination of the WAK15 grade and an uncoated carbide substrate provides a very sharp cutting edge and a low friction contact zone, specifically optimised for aluminium and other non‑ferrous materials. The included L55T chipbreaker promotes short, controllable chips and reduces the risk of material build‑up on the tool flank, which improves surface finish and decreases downtime for cleaning. For production environments where cycle times and part quality matter, this geometry supports consistent removal rates and predictable tool behaviour under moderate cutting parameters.

Robust geometry for process security and repeatable tool life

The rectangular 09 format combined with a 0° negative rake strengthens the cutting edge and increases resistance to edge chipping during interrupted cuts or when facing variable workpiece conditions. This results in improved process security and repeatable tool life across batches. The insert’s tolerance class H and the Walter N‑series integration ensure stable seating in compatible toolholders, reducing vibration and improving dimensional stability of produced parts. The negative rake also allows slightly higher feed rates where required, without sacrificing edge integrity.

System integration and handling benefits for the workshop

As part of the Walter N‑series, this insert fits into a proven ecosystem of toolholders and support fixtures that simplify tool setup and replacement. The nominal thickness and rectangular outline permit a straightforward indexable strategy: when an edge becomes dull, the insert can be indexed or replaced to restore cutting performance quickly. For teams transitioning from solid tools to indexable systems, the uncoated carbide nature of the grade avoids coating interference in soft metals, helping to maintain predictable cutting forces and a consistent surface appearance on the finished component.

FAQ

What materials is this insert suitable for?
The LNHX0904PDR-L55T WAK15 insert is designed primarily for aluminium and other non‑ferrous metals; the WAK15 grade and L55T chipbreaker reduce material adhesion and improve surface finish.

Is the insert coated or uncoated?
This milling insert uses an uncoated carbide grade (WAK15), chosen to maintain sharp cutting edges and low friction when machining soft, adhesive materials.

What does the 0° negative rake mean for machining?
A 0° negative rake provides a stronger cutting edge and better resistance to chipping during interrupted cuts, enhancing process security and repeatable tool life with this insert.

Which tool system accepts this insert?
The insert is part of the Walter N‑series and is compatible with corresponding Walter toolholders that accept a rectangular 09 insert with this geometry.

How does the L55T chipbreaker affect chip control?
The L55T chipbreaker produces short, controllable chips when machining aluminium and similar materials, reducing the risk of entanglement and improving machine and operator safety.
