The American Sanders OBS-18 is the industry’s most powerful orbital floor sander, trusted by flooring professionals for delivering a smooth, swirl-free finish on hardwood floors. With a heavy-duty 1 HP motor and 3,600 orbits per minute, the OBS-18 removes scratches left by drum or rotary sanders—leaving floors perfectly prepped for staining or sealing.
Its random-orbital action makes it the ideal choice for intercoat abrasion, screen & recoat, and fine finish sanding. The OBS-18 and OBS-18DC models also offer exceptional dust containment compatibility, enhancing job site cleanliness and reducing post-sanding cleanup.
