BCHT120408L-K85 WXN15 K85 Wendeplatten - Walter Tools

Reliable milling performance for non‑ferrous components is achieved through the sharp, uncoated WXN15 grade combined with the K85 chipbreaker and a parallelogram 75° geometry for stable engagement; this results in controlled chips and consistent edge life.

BCHT120408L-K85 WXN15 milling indexable insert — uncoated grade for non‑ferrous metals | Walter Tools

BCHT120408L-K85 WXN15 is a parallelogram 75° milling indexable insert engineered for sharp cutting in non‑ferrous materials with a K85 chipbreaker and a 7° clearance angle

• Parallelogram 75° geometry for versatile milling
• Uncoated carbide WXN15 for non‑ferrous metals
• K85 chipbreaker for controlled chip formation
• 7° clearance angle for smooth cutting action
• 0.8 mm corner radius for edge strength

Optimised for non‑ferrous metals and clean cutting

The insert uses the WXN15 uncoated carbide grade developed for the machining of non‑ferrous metals (ISO 513 group N). Its deliberately sharp edge geometry reduces material adhesion and minimises built‑up edge when machining aluminium, copper and brass. This results in predictable cutting behaviour and fewer interruptions in production, allowing a measurable improvement in process stability when paired with suitable feeds and speeds.

Controlled chip formation for continuous operation

The integrated K85 chipbreaker and the Parallelogram 75° geometry work together to produce short, manageable chips and to stabilise the cut at entry and exit. The 7° clearance angle reduces friction on the flank face, while the 0.8 mm corner radius balances edge robustness with cutting sharpness. These features directly contribute to reduced rework rates and longer periods between indexings, supporting a more efficient milling cycle.

Repeatable mounting and predictable results on the shop floor

Designed within the Walter N‑Series, the insert delivers repeatable seating and indexing in compatible milling bodies. The proven shape and chip control simplify process planning: once the insert grade and chipbreaker are matched to the work material, consistent surface finish and dimensional reliability follow. The tolerance class H ensures dependable interchangeability across tool holders that accept this format.

Practical benefits and recommended use

The uncoated nature of the grade favours applications where a very sharp cutting edge is required and where thermal coating advantages are less critical, such as high‑feed aluminium or copper machining. The designation and series details support straightforward tool management and spare part logistics. For best results, combine the insert with cutter bodies specified for parallelogram inserts and observe standard precautions for machining non‑ferrous metals to avoid built‑up material on the cutting edge.

FAQ

Which materials is this insert best suited for? The WXN15 grade is optimised for non‑ferrous metals; the BCHT120408L‑K85 insert is therefore especially suitable for aluminium, copper and brass, in line with ISO 513 group N.

Is the insert coated or uncoated? This milling insert is uncoated; the WXN15 carbide grade delivers a very sharp cutting edge for adhesion‑sensitive non‑ferrous machining.

What advantage does the K85 chipbreaker provide? The K85 chipbreaker promotes controlled chip formation and prevents long, stringy chips, improving process continuity and reducing the risk of workpiece damage during milling.

How does the parallelogram 75° geometry affect tool performance? The parallelogram 75° shape offers stable entry and exit conditions and supports predictable engagement angles, which helps to maintain surface quality and repeatable results with this insert.
