BCHT160520R-K85 WXN15 milling indexable insert — K85 chipbreaker, 7° clearance (Walter Tools)

A BCHT160520R-K85 WXN15 milling indexable insert engineered for sharp, uncoated cutting of aluminium, brass and other non‑ferrous metals, offering controlled chip formation and repeatable performance

• Uncoated carbide grade WXN15
• Optimised K85 chipbreaker geometry
• 7° clearance angle for smooth cuts
• Parallelogram 75° shape, 2 mm corner radius

Consistent chip control and surface quality for non‑ferrous work

The insert combines the WXN15 uncoated carbide with an optimised K85 chipbreaker, which together promote short, manageable chips and reduce the risk of material build‑up on the cutting edge. For machining aluminium and similar materials, a sharp, uncoated edge lowers friction and prevents welding of workpiece material to the tool, resulting in improved surface finish and fewer interruptions. The insert’s geometry is designed to be process‑reliable, so tool life becomes predictable and setup times can be reduced.

Geometry that supports accuracy and tool life

A parallelogram 75° shape with a 2 mm corner radius and a 7° clearance angle gives a favourable approach angle for stable cutting forces and even load distribution across the edge. The geometry, combined with the insert’s series specification (Walter N‑Series), makes it suited for high‑feed and finishing passes where dimensional accuracy matters. The modest corner radius offers a good compromise between strength and fine edge definition, which helps maintain consistent component tolerances over longer production runs.

Practical advantages in the workshop and process planning

Being part of the Walter N‑Series and specified for non‑ferrous metals, the insert is intended for applications that require low adhesion and reliable chip evacuation. The BCHT160520R-K85 WXN15 is supplied in a format that fits standard toolholders for parallelogram inserts, enabling quick indexation and minimal downtime during tool changes. Clear, measurable geometrical data simplifies programming and process documentation, supporting efficient integration into CNC milling cycles and predictable maintenance intervals.

FAQ

What materials is this insert designed for?
The BCHT160520R-K85 WXN15 insert is specified for non‑ferrous metals such as aluminium and brass; the uncoated WXN15 grade and K85 chipbreaker reduce material adhesion during cutting.

How does the K85 chipbreaker improve machining?
The K85 geometry on the Walter Tools insert promotes short chips and controlled evacuation, which supports stable cutting conditions and a consistent surface finish when machining non‑ferrous materials.

Can this insert be used for finishing passes?
Yes, the parallelogram 75° shape with a 2 mm corner radius and 7° clearance provides the edge strength and approach angle suitable for finishing and semi‑finishing operations.
