The sanding head assembly (124) has a drive disk (514), and a sanding disk (516) which are operatively coupled to the gearbox (414) by a flexible drive cable (416). A dust tube extends from the vacuum assembly (400) through the body tube (114) and is connected to the sanding head assembly (124) dust ring (534) by a flexible dust tube (122).
