The Mafell NFU 50 Groove-Cutting Machine (Ref. 918723) is a heavy-duty timber construction tool engineered for cutting lengthwise and crosswise grooves, frieze blocks, false floors, birdsmouth joints up to 45 degrees, and tenons. Powered by a 2300 W (3.1 hp) motor operating on 240V power, this machine delivers a maximum cutting depth of 1 15/16 in. (50 mm) without a guide track and 1 3/4 in. (44 mm) with a guide track, utilizing an included 2 3/8 in. (60 mm) wide cutter head.

Constructed with a lightweight magnesium die-cast housing and impact-resistant fiberglass-reinforced plastic components, the NFU 50 delivers structural rigidity for demanding jobsites. The 2-in-1 cutting depth adjustment mechanism enables fast, accurate depth settings, while a single-button release disconnects the machine from its cross-cut track for freehand or guide rail operation. For operator safety, an integrated hydraulic brake stops cutter rotation within 3 seconds, paired with a flashing LED status light that alerts when the spindle is actively turning. The 58 mm (2 5/16 in.) dust extraction port rotates and locks into position to maintain clear sightlines during heavy chip removal.
