The new Mafell DDF 40 Duo Dowel System introduces greater ease and efficiency to the task of drilling accurate dowel holes.  Its hallmarks include a broad range of applications, an ergonomic design, a flat base plate for easy handling, and joints that are absolutely aligned and stable.  Whether in the workshop or on site, no other 230 V power tool can produce such high-quality joints.

When producing corner joints, partitions, or rows of holes, the DDF 40 offers not only the precision of a stationary machine, but also the cost savings associated with standard wooden dowels.  In addition, the technique of using dowels in pairs achieves outstanding stability at the dry assembly stage.

Smart accessories make the DDF 40 a convenient multi-purpose machine.  In most cases you do not need to use a template or mark out the work, thanks to the variety of stops and fences.  This MaxiMAX version in the “T-Loc” systainer includes the innovative SA 320 Side Fence Set and LA Stop Pin Insert for Battens in the Standard Equipment.

Mafell has put together an excellent DDF 40 Brochure and a host of videos showing the many different ways in which the DDF 40 can be used:
