Milling indexable insert LNGX130708R-L88 WXN15 – uncoated carbide for non‑ferrous metals (Walter Tools)

A LNGX130708R-L88 WXN15 milling indexable insert engineered for sharp, uncoated cutting of aluminium, copper and brass in finishing and semi‑finishing applications.

• Uncoated carbide for non‑ferrous metals
• Negative 0° clearance for stable engagement
• Chipbreaker L88 for controlled chip formation
• Rectangular 13 format with 0.8 mm radius

Consistent machining for non‑ferrous materials

The insert is based on the WXN15 uncoated carbide grade, optimised for machining non‑ferrous metals such as aluminium, copper and brass. The combination of a very sharp cutting edge and the chipbreaker L88 reduces material adhesion and promotes predictable chip flow, which in turn lowers rework and improves throughput. This makes the component particularly suitable for high‑precision finishing where surface quality and repeatability are decisive.

Geometry that stabilises the process and extends edge life

With a rectangular form and an insert size of 13, the geometry provides a stable seating and predictable cutting forces. The 0.8 mm corner radius balances edge strength and surface finish, and the 0° (negative) clearance ensures a controlled entry angle for interrupted cuts or shallow radial engagements. These features together reduce edge chipping and enable longer tool life, resulting in fewer indexings and a steadier production rhythm.

Practical advantages and application guidance

The uncoated design of this grade supports very sharp edges and is therefore preferred for uncoated applications on NE‑materials; the insert is not coated, which simplifies edge replacement strategies and avoids coating‑related adhesion on soft alloys. The LNGX130708R-L88 WXN15 insert is intended for users seeking consistent chip control and reliable finishing results; pairing it with appropriate feeds and a chip evacuation strategy will maximise performance.

FAQ

Which materials is this insert suited for?
The LNGX130708R-L88 WXN15 insert is designed for non‑ferrous metals — chiefly aluminium, copper and brass — using the WXN15 uncoated carbide grade for reduced adhesion and predictable cutting.

Is the insert coated, and what is the practical consequence?
This insert is uncoated (WXN15). The uncoated edge allows a very sharp cutting geometry, which is advantageous for soft, sticky alloys where coatings can promote build‑up.

What role does the chipbreaker L88 play in machining?
The L88 chipbreaker shapes and breaks chips to improve evacuation and reduce the risk of material reattachment on the cutting edge, supporting consistent surface finish and fewer interruptions.

How does the negative 0° clearance affect cutting?
A 0° (negative) clearance provides a controlled engagement angle that can stabilise the insert during side cutting and in interrupted cuts, enhancing edge robustness in demanding passes.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm radius offers a compromise between edge strength and surface quality: it reduces the risk of chipping while still allowing fine finishing passes when combined with appropriate feeds.
