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 mortise. 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 (4 mm, 5 mm, 6 mm, 8 mm and 10 mm) 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 implies, 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)
