BCMT120408R-F55 WAK15 milling indexable insert – Parallelogram 75° geometry, for aluminium and non‑ferrous metals — Walter Tools

A BCMT120408R-F55 WAK15 is an indexable milling insert engineered for high-efficiency removal of aluminium and other non‑ferrous materials, combining a sharp uncoated grade with a positive cutting geometry for smooth, predictable performance

• Parallelogram 75° geometry for positive cutting
• WAK15 uncoated carbide for aluminium machining
• 0.8 mm corner radius for improved edge strength
• Chipbreaker F55 reduces built-up edge

Faster, more efficient machining of non‑ferrous metals

The insert’s WAK15 composition is an uncoated carbide grade optimised for machining aluminium and similar non‑ferrous materials. The chosen grade minimises adhesion and promotes a sharp cutting edge, which translates into higher cutting speeds and improved cycle times. With these properties, the indexable insert delivers a clear economic advantage through increased productivity and fewer tool-change interruptions, while the specified chipbreaker F55 supports stable chip formation and reduces rework caused by material build-up.

Geometry that improves finish and process stability

The Parallelogram 75° form and a 0.8 mm corner radius provide a balance between accessibility and edge robustness. The positive geometry helps to reduce cutting forces, which leads to lower spindle loads and a more consistent surface quality on the workpiece. The 7° clearance angle further supports a clean shear action and helps prevent rubbing on thin-walled or delicate workpieces. Together, these geometric features enable repeatable accuracy and reduced vibration during milling.

Controlled chips and predictable tool life for reliable production

Chip control is central when machining soft, ductile materials; the F55 chipbreaker is tuned to break and evacuate swarf consistently, reducing the risk of built‑up edge and improving operator safety. The insert’s dimensions — a nominal insert size of 12 mm and a plate thickness of 4 mm — provide mechanical stability while maintaining the ability to generate fine finishes. The result is a predictable wear behaviour that supports consistent part quality and reduces unexpected downtime.

FAQ

What materials is this insert suitable for?
The BCMT120408R-F55 WAK15 insert is designed primarily for aluminium and other non‑ferrous metals, as indicated by the WAK15 grade and ISO group N designation.

How does the Parallelogram 75° geometry help production?
Parallelogram 75° geometry provides a positive cutting approach that reduces cutting forces and improves access, resulting in smoother cuts and better surface finish for non‑ferrous machining.

What benefit does the F55 chipbreaker provide?
The F55 chipbreaker promotes consistent chip formation and evacuation, reducing the likelihood of built‑up edge and supporting stable tool life when machining ductile materials.

Is the insert coated?
No, the WAK15 grade of this insert is an uncoated carbide specifically selected to maintain a sharp cutting edge on soft, adhesive materials like aluminium.

Can this insert be used for finishing operations?
Yes; the 0.8 mm corner radius and positive geometry make the insert well suited to operations that require a fine surface finish on non‑ferrous components.
