For general furniture and project finishing, start by comparing a variable-speed random orbital sander with usable dust extraction and readily available abrasives. Comfort and extraction are more useful than chasing a single maximum-speed number.
Choose by the work you actually do
| Your situation | Start with | Tradeoff to check |
|---|---|---|
| Occasional projects at a bench | Corded random orbital sander | No battery weight or runtime planning |
| Work moves around the garage | Cordless sander on an existing platform | Include battery weight and extraction hose |
| Long finishing sessions | Comfortable grip and matched extraction | Compare vibration, hose drag, and abrasive cost |
| Fast stock removal | Different abrasive or sanding tool may fit | A finish sander is not always the right roughing tool |
What to compare before buying
Compare the sanding system
Disc diameter, hole pattern, backing pad, extraction adapter, and abrasive availability all interact. Check whether the papers you plan to buy match the pad and whether a replacement pad is available. A bargain tool with awkward consumables can be expensive to keep using.
A general-purpose corded candidate
The DEWALT DWE6423 is listed by its manufacturer as a variable-speed random orbit sander. It offers a useful corded comparison point. Check its extraction connection and handling against the other tools on your shortlist rather than assuming a dust bag will meet your whole-garage cleanup needs.
Use a finishing sequence
Start with the grit needed to remove the actual defects, then progress appropriately for the material and finish. Clean between stages and inspect under task lighting. More pressure and a longer session are not substitutes for the right abrasive and extraction setup.
Your purchase checklist
- Disc size, hole pattern, and replacement-pad availability
- Grip, installed weight, and control access
- Hose compatibility and pad extraction openings
- Abrasive availability and ongoing cost
A common buying question
Does a dust bag replace a dust extractor?
A bag can collect some debris, but it is not the same as a connected extraction system. Choose dust control for the tool, material, and work rather than the visible amount of dust alone.
