BCHT120404L-K85 WXN15 Fräswendeschneidplatte – milling insert, uncoated carbide, for non‑ferrous metals | Walter Tools

BCHT120404L-K85 WXN15 is a parallelogram 75° milling insert designed for efficient and controlled machining of non‑ferrous metals in medium‑ to high‑productivity production.

• Uncoated carbide grade for NE materials
• Parallelogram 75° insert geometry
• K85 chipbreaker for stable chip control
• 7° clearance angle with 0.4 mm corner radius

Consistent chip control for non‑ferrous machining

The insert delivers stable cutting behaviour through its K85 chipbreaker and the sharp uncoated carbide of the WXN15 grade. For machining aluminium, brass and other NE materials, a sharp edge reduces the risk of built‑up edge and material adhesion; the uncoated WXN15 grade is optimised precisely for these applications. The combination of chip geometry and edge form aims to produce short, manageable chips, which supports uninterrupted production and reduces time lost to clearing chips or reworking parts. This results in a visible improvement in process reliability and surface consistency.

Geometry that improves engagement and surface quality

The parallelogram 75° form and the 7° clearance angle influence cutting forces and approach angle, offering a balance between robustness and light cutting action. A 0.4 mm corner radius provides a predictable profile on the machined edge while maintaining a sharp enough edge for delicate finishes on non‑ferrous components. These geometric attributes help to reduce chatter in common milling setups and contribute to an improved surface finish on cast or wrought NE materials. Where finish is a priority, the insert geometry supports stable contact between workpiece and tool without sacrificing edge life.

Practical advantages during production

With its designation and series alignment within the Walter N‑series, the insert suits workshops seeking efficient, reproducible results on non‑ferrous work. The insert thickness and size align with common toolholder systems for 75° approach angles, simplifying upgrade or replacement. Because the grade is uncoated carbide, it performs particularly well where low friction and a very sharp edge are required; this also eases post‑cutting cleaning and minimises thermal buildup. Reduced downtime for chip management and consistent cutting behaviour translate into improved throughput and lower overall machining cost per component.

Compatibility, handling and selection guidance

The insert is supplied in a T execution and follows the standard ISO designation shown on the item label, enabling straightforward matching with corresponding toolholders. When selecting cutting parameters, priority should be given to moderate feed per tooth and suitable speeds for the chosen non‑ferrous alloy to exploit the sharp geometry. The insert is intended for NE materials; for steels or hardened alloys, choose an alternative grade designed for those materials. For further guidance on feed and speed windows or holder recommendations, the Metav Werkzeuge technical team can provide application‑specific advice and ensure the correct insert and holder pairing.

FAQ

What materials is this insert intended for?
The BCHT120404L-K85 WXN15 insert is optimised for non‑ferrous metals (NE group) such as aluminium, copper and brass thanks to its sharp uncoated carbide grade and chip‑control geometry.

Is the insert coated, and what are the implications?
This insert uses an uncoated carbide grade (WXN15); the lack of coating maintains a very sharp edge, which helps prevent material adhesion when machining NE materials and supports low‑friction cutting.

What benefit does the K85 chipbreaker provide?
The K85 chipbreaker produces consistent, controllable chips when milling non‑ferrous alloys, reducing the risk of entanglement and improving process stability and surface quality.

Which toolholder geometry is compatible with this insert form?
The parallelogram 75° plate form indicates compatibility with toolholders designed for a 75° approach; confirmation of holder model and insert seating should be checked against the ISO designation on the insert.

Can this insert be used on steel or hardened materials?
The WXN15 grade and the insert geometry are intended for NE materials; for steel or hardened alloys, select a grade and geometry specified for those workpiece materials rather than this insert.
