Festool has taken the domino joining process and tremendously decreased the time in which the process is completed. The Festool domino joining system is comprised of pre-fabricated beech and sipo tennons and of course the joiner. While equipped with easily adjustable mortise sizing, never again worry about creating flawed or wrongly sized mortises again. Festool also wanted to beef up the convenience of the Festool domino joiner 500 by including a large gluing surface are for extra strength as well as making it 100% rotation proof. An adjustable fence angle, retractable stop flaps, an adjustable cutter and step gauge, make the Festool domino joiner 500, the last one you ever purchase!
