BCHT120420L-K85 WXN15 milling indexable insert — sharp uncoated grade, parallelogram 75° | Walter Tools

The BCHT120420L-K85 WXN15 is a milling indexable insert designed for high‑performance machining of non‑ferrous metals, offering a sharp, uncoated carbide grade and a K85 chipbreaker in a parallelogram 75° form for controlled chip flow and reliable surface quality.

• Uncoated carbide grade WXN15
• K85 chipbreaker for sharp edges
• Parallelogram 75° insert geometry
• 7° relief angle and 2 mm corner radius

Faster, cleaner milling of non‑ferrous metals

The combination of a sharp, uncoated carbide grade and a purpose‑built K85 chipbreaker reduces material adhesion and promotes predictable chip formation when machining aluminium, copper and brass. This results in higher feed rates and consistent surface quality, while the cutting edge geometry lowers the risk of material build‑up. For shops seeking efficiency in NE‑metal applications, the insert’s design supports stable process windows and shorter cycle times.

Reliable geometry for flexible setups

The parallelogram 75° form provides versatile cutting angles and stable clamping in standard milling holders. The modest 7° relief angle helps maintain edge strength during interrupted cuts, while the 2 mm corner radius balances edge robustness and surface finish. These geometric choices allow integration into existing tool systems with minimal compromise on performance, supporting a range of milling strategies from light finishing to more aggressive roughing in non‑ferrous alloys.

Clear specification and repeatable results

Manufactured to a tolerance class H, the insert delivers repeatable dimensions for predictable tool offsets and programming. The Walter N‑Sortensystem series with grade WXN15 offers an uncoated carbide tailored to non‑ferrous materials, making the component suitable for production runs where consistent part quality and predictable tool life are priorities. The standardised geometry simplifies tool management and reduces setup variations across batches.

Application advantages and process security

Using an insert with the described features improves process security through optimised chip control and reduced thermal loading on the cutting edge. The specification emphasises quick chip evacuation and minimal adhesion, which together enhance tool life and reduce rework. Where surface finish and dimensional consistency matter, the insert supports a balance between productivity and component quality, particularly for parts machined from aluminium alloys and other NE‑metals.

FAQ

Which materials is this insert intended for?
The BCHT120420L-K85 WXN15 insert from Walter Tools is optimised for non‑ferrous metals such as aluminium, copper and brass (ISO group N), using a sharp, uncoated carbide grade to minimise adhesion.

Is the WXN15 grade coated or uncoated?
WXN15 is an uncoated carbide grade; the lack of coating and the sharp edge geometry help prevent material build‑up when machining soft, adhesive materials.

What advantages does the K85 chipbreaker provide?
The K85 chipbreaker promotes clean chip formation and consistent evacuation, improving surface finish and reducing the chance of built‑up edge during milling of NE‑metals.

What are the key dimensions and tolerances of the insert?
The insert is manufactured to tolerance class H, with a 12 mm size, 4 mm thickness, 2 mm corner radius and a 7° relief angle — dimensions that support stable clamping and repeatable offsets.

Which series does this insert belong to and who manufactures it?
This insert is part of the Walter N‑Sortensystem series and is supplied by Walter Tools under the designation BCHT120420L-K85 WXN15.
