Overview
The Genesis GBS321A is a corded sander running on 120 volts and drawing 8 amps, with a listed speed of 18,000 RPM. At 7.8 pounds it's built for two handed operation over extended sanding sessions.
An 8 amp draw is solid for a sander in this weight class, and the high listed speed points to a tool meant for fast material removal rather than fine finish work alone. The category places it among sanders generally, without specifying belt, orbital, or disc style, so check the listing photos to confirm the exact format.
