History and description
This tool, first on sale in 2006, cuts mortises in the manner of a biscuit joiner. 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 five 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°.
Advantages
- Allows very quick joinery, useful in a commercial carpentry setting.
- Flat tenons resists torquing.
- Stronger than a biscuit
Disadvantages
- High tool cost comparative to other joinery methods
- Proprietary tenons (dowels) required
- Brushes (motor) and bits will wear out in time
- Noise and dust (dust extraction required)
- Mortises overcut (i.e. the mortise is visibly larger than the domino) reducing strength.
