The Domino in action

The Domino is a loose mortise and tenon joining tool manufactured by the German company Festool.

History and description[edit]

This tool, first on sale in 2007,[1] cuts mortises in the manner of a biscuit joiner. A drill-like rotating cutter cuts a round-ended mortice. Each plunge creates a mortise that is sized to accept a Domino loose tenon, creating joints in stock from 22.2 millimetres (0.87 in) wide. There are five cutter sizes (4mm, 5mm, 6mm, 8mm and 10mm) for six different Domino tenon sizes. Self-referencing pins allow the cutting of rows of evenly spaced mortises with no need to measure and mark. Mortise width is adjustable in three increments with the turn of a knob, and cuts can be overlapped for long mortises. Fence tilts from 0-90°, with stop positions at 0°, 22.5°, 45°, 67.5°, 90°.

Domino XL[edit]

The Domino XL is, as the name states, the Domino's larger cousin. It uses the same cutter design as the original Domino, yet uses much larger tenons.


  • Allows very quick joinery, useful in a commercial carpentry setting.
  • Flat tenons resists torquing.
  • Stronger than a biscuit joiner.


  • High tool cost comparative to other joinery methods
  • Proprietary tenons (dowels) required
  • Noise and dust (dust extraction required)
