Overview
The RIDGID 28533 is a corded electric sander built for 120 volt outlets, drawing 6.5 amps and running at a fixed 950 RPM. At 8.2 pounds it stays manageable for a corded tool, though pad size and included accessories are not specified.
RIDGID's listing here leans on spec numbers rather than a marketing description, so what's confirmed is the electrical draw, the fixed speed and the weight. There is no listed pad or belt size, which matters if you are trying to match it with existing sanding accessories.
- 120 volt corded electric power source
- 6.5 amp motor draw
- Fixed sanding speed of 950 RPM
- Weighs 8.2 pounds
Who it's for
Buyers already familiar with RIDGID's sander lineup, who mainly need to confirm the amperage and RPM before adding this to a corded tool collection, are the best fit. Anyone needing a specific pad diameter or a cordless option should look elsewhere, since neither is confirmed here.
Pros and cons
- Runs on standard 120 volt household current
- 6.5 amp motor at a fixed 950 RPM
- Manageable 8.2 pound weight for a corded tool
- No pad or belt size listed
- Single fixed speed rather than variable
- No included accessories specified
Performance notes
At 950 RPM the 28533 runs at a single fixed speed rather than a variable range, and its 6.5 amp draw on a 120 volt circuit is typical for a corded sander of this size. Being corded, it avoids battery runtime limits but ties the tool to an outlet or extension cord.
