Festool recently released the Domino XL DF 700, big brother to its revolutionary Domino DF 500, one of the most innovative tools of the last few decades. Aside from the size, the loose-tenon joints created by the XL are the same as with the earlier version. From a machine that resembles a biscuit joiner, a router-type bit both plunges and oscillates to cut mortises in mating parts. Into each mortise fits a loose tenon, or “Domino.”
How’s the fit? As good as I’ve seen, whether cut by hand or power. And lining up the joint couldn’t be easier.Cut butt joints on square or angled parts, align the two mating pieces and mark the tenon location on both pieces with one quick swipe of your pencil. Line up the machine and make the plunge cuts. The XL also has an improved indexing system that allows for even less measuring.
