A single-disc rotary sander used for buffing, screening and light sanding rather than heavy stock removal, which is why floor contractors keep one alongside a belt or drum sander rather than instead of one. Its 407mm disc and 1.9kW motor put it in the same bracket as other single-phase rotary buffers sold through UK flooring trade counters.

The DOMINO DF 500 replaced traditional dowelling and biscuit jointing for many furniture makers and joiners, letting them cut precise mortises for loose tenons quickly. It has no direct equivalent from the other brands in this catalogue, which is part of its appeal to Festool users.
