MAFELL DDF 40 MidiMAX DuoDübler is a professional dowel drill for highly precise, stable joints in the workshop and on installation jobs. Its compact design, ergonomic handling and patented stop technology achieve precision usually associated with stationary machines.
DDF 40 uses double-hole technology, drilling two precisely positioned dowel holes in one operation. This prevents the workpieces from twisting relative to each other after joining, simplifies alignment and ensures a very stable, dimensionally stable joint.
32 mm drill spacing makes the machine suitable for professional hole rows and fitting holes, so DDF 40 is especially practical in carcass construction and furniture assembly. Standard round wooden dowels also allow cost-effective joints.
The patented stop system uses spring-loaded stop pins integrated into the base plate. These let you reliably drill repeat holes 15.5 mm from the workpiece edge, without measuring and marking each hole individually.
The height of the swivelling stop can be precisely set 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 fixed positions at 22.5°, 45° and 67.5°.
DDF 40 flat housing and flat base plate combine the simple handling of a biscuit jointer with the advantages of a classic dowel joint. The ergonomically shaped motor housing ensures a secure grip and efficient power transfer when drilling.
The 900 W universal motor, 8000 rpm no-load speed and drilling depth up to 40 mm let DDF 40 be used with both solid wood and panel materials. The integrated extractor connection helps remove chips and dust from the drilling area.
The MidiMAX version comes in a T-MAX case with two 8 mm carbide drills and 200 wooden dowels, offering a practical ready-to-use kit for professional dowelling.
