The Mafell Arunda 50N Midi Dovetail Joint Milling Template System is engineered for creating high-precision timber-to-timber dovetail connections in narrower structural wood members. Built for timber widths between 45 mm and 80 mm (1-3/4 in. to 3-1/8 in.) and heights from 90 mm to 300 mm (3-1/2 in. to 11-13/16 in.), this system produces strong, aesthetic, hardware-free joinery ideal for joists, purlins, and light timber frame construction.

Paired with a compatible heavy-duty router such as the Mafell LO 65 Ec, the Arunda 50N uses a two-piece template system to router-cut self-tightening tenons and mortises. The interlocking dovetail design wedges securely in place during assembly, drawing members tightly together while maintaining structural load capacity. The standardized reference stops on each template eliminate manual recalculations, improving shop productivity and site installation efficiency.

This Midi complete set supplies essential job-ready components, including male and female templates, specialized cutter head, guide ring, alignment gauge, spare reversible carbide blades, and a sturdy wooden carrying case.

Features & Benefits

• Flexible Angle Cutting: Supports square perpendicular joints as well as angled cuts up to 50 degrees for roof structure framing.

Choose the Arunda 50N for narrow timber dimensions spanning 45 mm to 80 mm (1-3/4 in. to 3-1/8 in.) with a 37 mm joint depth. For larger timber widths, select the Arunda 80N (80 mm to 140 mm) or 120N (120 mm to 200 mm). Choose the Arunda 60-1B if working with wider timber up to 120 mm that requires a shallower 21 mm joint depth.
