Joining has always been a slow, difficult process. Never again, thanks to the Biscuit Joiner Electric Machine. It is 100% rotation-proof and far stronger than either biscuits or dowels. It also has a large gluing surface area for extra strength. The unique, patented cutting mechanism consists of a spiral cutter with carbide tip that oscillates as it rotates to create perfect mortises time after time. This action creates a clean entry for a perfectly flush surface while preventing heat build up in the tooling for long cutter life. The adjustable fence for mitered and beveled joints ranges from 0 to 90º with positive stops at 22.5, 45, 67.5, and 90º. Straightforward adjustments for mortise width and depth, and material height.
