GEM Industries invented the Orbital Polisher for car, boat, and plane detailing almost 50 years ago and has been in uninterrupted production ever since. The GEM Orbital Polisher is currently sold throughout the world and recognized as the premier quality buffer for the professional detailer. In 2001, GEM modified and enhanced the polisher, turning the machine into the hottest sander to hit the Solid Surface and Wood industries in decades. The 11" head cuts sanding time by as much as 70%!!
