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.
- 120 volt, 8 amp corded motor

Who it's for
Suits users tackling larger corded sanding jobs where consistent power matters more than portability. Less suited to anyone needing a compact cordless sander for quick touch ups.
Pros and cons
- Solid 8 amp motor for sustained sanding
- High 18,000 RPM speed rating
- Manageable 7.8 pound weight
- Sanding format such as belt or orbital not specified

Performance notes
An 8 amp draw at 120 volts gives the motor enough power for sustained use, and the 18,000 RPM speed rating suggests fast stock removal. At 7.8 pounds it sits in a manageable range for extended handheld sessions without becoming a strain.
