The domino XL saves you time and space because you're occupying a small amount of space in additon to reducing set-up and machining time. For large-scale joinery, this Festool joiner is perfect because it uses thicker, longer tenons up to 5 1/2 inch in length. Your work performance is more efficient as you rapidly switch between a wide range of joint sizes using simple controls and adjustments. This domino XL joinery system allows you to do precise, reliable adjustments and stops in a matter of seconds unlike what has traditionally taken hours. You're essentially saving time and energy with having perfect, clean, and repeatable mortises every time. Buying new materials for re-cutting work is not necessary with the patented oscillating cutter action because it reduces the chance of kickback. Backed by a three-year warranty, Festool guarantees a quality power tool and years of reliable service.
