BCHT120412R-K85 WXN15 — Fräswendeschneidplatte for non‑ferrous metals (Walter Tools, K85 chipbreaker, 7°)

BCHT120412R-K85 WXN15 is a solid, indexable milling insert designed for high‑quality finishing and productive machining of non‑ferrous materials

• WXN15 uncoated carbide for non‑ferrous metals
• K85 chipbreaker for clean swarf control
• Parallelogram 75° geometry for stable cutting
• 7° clearance and 1.2 mm corner radius

Precise, low‑adhesion machining for non‑ferrous materials

The insert’s WXN15 composition is an uncoated, sharp cemented carbide grade optimised for non‑ferrous workpieces. This combination reduces built‑up edge and adhesion on soft metals such as aluminium, copper and Messing, which in turn improves surface finish and reduces rework. The K85 chipbreaker promotes predictable chip formation, making coolant use and chip evacuation more efficient; this leads to higher average feed rates and improved process throughput. In production environments where minimising material transfer and maintaining consistent part quality matter, this configuration reduces cycle time without sacrificing surface integrity.

Consistent geometry for repeatable results and tool life

The 75° parallelogram insert form together with a 7° clearance angle yields a robust mounting position and reliable chip flow direction. The specified corner radius 1.2 provides a balanced edge strength for fine finishing while still resisting premature edge chipping. Tolerance class H and the stable design support repeatable indexing and predictable wear behaviour on multi‑edge tooling systems. As a result, set‑up variance is reduced and process capability is improved, which supports leaner inventory management and fewer unexpected tool changes on the shop floor.

Simple integration and production benefits

Designed for the Walter N‑Sortensystem, this insert is compatible with common indexable cutter bodies and can be integrated into existing tool cycles with little adjustment. The plate’s designation and execution ensure interchangeability and straightforward spare‑part handling, reducing machine downtime. With its uncoated sharp edge geometry and the K85 chipbreaker, the component is particularly suited to applications demanding high surface quality and minimal burr formation. For practical deployment, cutting data sheets are recommended to fine‑tune feeds and speeds according to machine rigidity and workpiece alloy, thereby securing the best balance between productivity and tool life.

FAQ

What materials is this insert intended for?
The BCHT120412R-K85 WXN15 insert is optimised for non‑ferrous metals such as aluminium, copper and Messing, with a sharp uncoated grade that minimises adhesion during cutting.

How does the K85 chipbreaker influence machining?
The K85 chipbreaker produces short, controlled chips and reduces material build‑up on the cutting edge, which improves surface finish and facilitates reliable chip evacuation when using the Walter N‑Sortensystem.

What does the 1.2 mm corner radius mean for part finish?
A 1.2 mm corner radius provides a compromise between strength and fine finish: it resists minor chipping while enabling smooth surface quality in finishing passes with appropriate feeds.

Is the insert compatible with standard Walter cutter bodies?
Yes, the insert is made for the Walter N‑Sortensystem and is compatible with matching indexable cutter bodies that accept the BCHT‑type plate.
