BCHT120412L-K85 WXN15 milling indexable insert – Walter Tools, for non‑ferrous metals

BCHT120412L-K85 WXN15 is a parallelogram indexable insert designed for efficient milling of non‑ferrous metals such as aluminium and brass

• Walter N‑series grade WXN15
• Sharp uncoated carbide grade
• Parallelogram 75° cutting geometry
• Chipbreaker K85 for non‑ferrous metals

Reliable chip control for non‑ferrous machining

The combination of the K85 chipbreaker and a sharp cutting edge creates controlled, short chips when machining non‑ferrous metals. This reduces the risk of material build‑up on the edge and minimises rework, resulting in fewer interruptions during production. The insert’s geometry has been developed to promote smooth evacuation of chips from the cutting zone, which supports higher feed rates and a steadier surface finish on aluminium and similar alloys.

Geometry tuned for predictable tool life and surface quality

A parallelogram 75° shape with a 7° relief angle and a 1.2 mm corner radius provides stable cutting behaviour and even load distribution across the cutting edge. These design elements help to avoid sudden tool failures and deliver a consistent edge condition over repeated tool changes. For workshop teams that prioritise repeatability, the insert’s form reduces vibration and contributes to a uniform surface finish, lowering the need for secondary finishing operations.

Uncoated carbide grade for sharp, adhesion‑resistant performance

The WXN15 grade is an uncoated carbide developed for sharp‑edge performance on NE materials; it resists material adhesion while maintaining a keen edge, which is especially advantageous when working with sticky or gummy aluminium alloys. With this grade, machining can be performed with lower cutting forces and improved dimensional stability. The result is a cost‑effective balance between productivity and the number of insert changes required in daily operation.

Practical benefits in production environments

The insert’s standardised ISO designation and familiar mounting profile make it straightforward to integrate into existing milling toolholders, reducing setup times and simplifying inventory management. The robust design supports reliable performance across mixed production batches, while the combination of sharp geometry and the K85 chipbreaker helps to reduce coolant dependency and cleaning effort during shifts, contributing to more efficient shopfloor workflows.

FAQ

Which materials is this insert intended for?
The BCHT120412L‑K85 WXN15 is intended primarily for non‑ferrous metals (designation N), such as aluminium, copper and messing.

Is the WXN15 grade coated?
No, WXN15 is an uncoated carbide grade designed for sharp‑edge applications and minimised material adhesion when machining NE materials.

What geometry advantages does the insert offer?
The parallelogram 75° shape combined with a 7° relief promotes stable cutting and the 1.2 mm corner radius helps to distribute cutting forces for consistent surface quality.

How does the K85 chipbreaker affect production?
The K85 chipbreaker improves chip fragmentation and evacuation when machining non‑ferrous alloys, which supports higher feed rates and reduces the risk of chip entanglement.
