Pros

  • Cuts a mortise for a loose tenon (Domino) rather than a biscuit slot -- significantly stronger joint

  • Oscillating cutter produces a mortise, not a slot -- the correct geometry for a tenon

Cons

  • Very high price -- the most expensive plate/domino joiner
  • Festool Dominos are proprietary -- an ongoing consumable cost
