The MAFELL DD40P PowerMAX Duo-Dowel System (120V, Ref. No. 916043) is a portable dowel jointer designed for fast, precise joinery in carcass construction, staircase building, and hardware fitting installation. Powered by a 1000 W (1.3 hp) universal motor, this system features a standard 32 mm (1 1/4 in.) drill spacing and a 0 to 40 mm (0 to 1 9/16 in.) drilling depth capacity, delivering reliable corner, edge-to-edge, and mitre joints across solid wood and composite board materials.

By utilizing standard wooden dowels with dual-bit drilling, the DD40P automatically aligns workpieces during assembly, simplifying or eliminating the need for complex clamping setups. A clear material thickness scale paired with a six-position turret stop allows rapid resetting across varied stock thicknesses, while continuously variable adjustments for depth and fence tilt angle ensure exact alignment across complex joint configurations.

Integrated retractable stop pins and auxiliary stops facilitate quick edge positioning without requiring layout markings. Dual-side locking on the fence mechanism maintains rigid, non-deflecting alignment throughout continuous production drilling.

Features & Benefits

• Dual-Dowel Operation: Uses two drill bits spaced at 32 mm (1 1/4 in.) to complete parallel dowel holes in a single pass, accelerating assembly and ensuring joint alignment.
• 1000 W PowerMAX Motor: Delivers robust power with a 13,500 RPM no-load speed for clean drilling in hard woods and board products.
• 6-Position Turret Stop: Pairs with a clear scale to enable fast, repeatable depth and stock thickness resets.
• Continuously Variable Adjustment: Precision controls for drilling depth up to 40 mm (1 9/16 in.), stock thickness, and fence tilt angle from 0 to 90 degrees.
• Integrated Edge Stop System: Retractable stop pins and auxiliary stops allow edge-referenced drilling without manual layout lines.
• Dual-Fastened Tilting Fence: Locks securely on both sides of the fence assembly to prevent slipping under drilling pressure.
• Versatile Tooling Capacity: Accepts carbide-tipped dowel drill bits from 5 mm (3/16 in.) to 16 mm (5/8 in.) diameter via an 8 mm chuck.
