MAFELL DDF 40 MaxiMAX DuoDübler is a professional dowel drill for precise, stable, dimensionally stable joints in furniture making, stair building, the workshop and installation. Its compact design, ergonomic handling and patented stop system provide stationary-machine precision in a hand-held tool.
Proven double-hole technology drills two precisely positioned dowel holes in one operation. This prevents the workpieces from twisting relative to each other after assembly, simplifies alignment and ensures very stable joints.
32 mm drill spacing makes DDF 40 suitable for professional hole rows and fitting holes, so the machine is especially practical in carcass construction and complete furniture assembly. Standard round wooden dowels also allow cost-effective joints.
The patented stop system uses spring-loaded stop pins. These let you reliably drill repeat holes 15.5 mm from the workpiece edge, without measuring and marking each hole individually.
The swivel stop height can be precisely adjusted with a rotary knob and scale up to 62 mm. Common dimensions can be preset with the revolver stop. For corner joints the stop can be swivelled infinitely 0–90°, with detent positions at 22.5°, 45° and 67.5°.
DDF 40 flat design and flat base plate combine the simple handling of a biscuit jointer with the advantages of a classic dowel joint. The ergonomic motor housing ensures a secure grip and optimal power transfer while drilling.
The 900 W universal motor, 8000 rpm no-load speed and drilling depth up to 40 mm allow use with solid wood and panel materials. The integrated extractor connection helps remove chips and dust from the drilling area.
The MaxiMAX version also includes the SA 320 side stop and LA strip stop, as well as 6 and 8 mm carbide drills, wooden dowels and an 8 mm glue nozzle, making the kit especially versatile for repetitive furniture and installation work.
The machine is part of the T-MAX transport and storage case configuration, keeping the machine and accessories practically organised and protected.
