Application & Handling

The NFU 50 impresses with its ergonomic operation and clear view of the cutting line. The rotating extraction nozzle (58 mm) enables clean work even with large amounts of chippings – perfect when combined with a professional dust extractor.

Flexibility in every application

Thanks to the swivel range of 0° to 45°, even precise angled grooves can be easily created. The machine can be removed from the rail with just one hand – for freehand milling or hard-to-reach areas.

Accuracy and leadership

The included L guide device enables controlled, linear milling up to 370 mm in length – ideal for timber framing infills, notches and more.

Robust, powerful, well thought out

The combination of a magnesium die-cast housing , glass-fiber reinforced plastic parts and high-quality workmanship makes the NFU 50 particularly durable – even under the toughest construction site conditions.
