Q: What is domino joinery in woodworking?
A: Similar in application to biscuit joinery, Festool’s Domino Joiner tool cuts mortises into the edges of wood boards or panels so they can be joined along those edges using tenons to bridge the pieces. Whereas biscuit joinery uses oval hardwood biscuits as the tenons, the newer Festool system utilizes angular domino-shaped tenons, which have a large gluing surface area for extra strength and they’re 100-percent rotation-proof and far stronger than either biscuits or dowels.
