Frequently asked

5 questions
What's the difference between a 5-inch and 6-inch random orbital sander?
A 6-inch pad covers roughly 40% more surface area than a 5-inch pad, which speeds up stock removal on large panels. Reviewers in r/woodworking note that 5-inch sanders are easier to control one-handed and have far cheaper, more widely available sanding discs, making them the better default for general DIY and furniture work. 6-inch tools shine for auto-body, big tabletops, and floor refinishing.
Are corded orbital sanders better than cordless?
For sustained sanding sessions, the consensus across mainstream tech press and Reddit tool communities is that corded sanders still deliver more consistent RPM under load and run indefinitely. Cordless models have closed the gap for short jobs, but several DeWalt-thread commenters note the corded versions hold pad speed better when you lean into the work.
How important is variable speed on an orbital sander?
Variable speed matters most for finishing work, polishing, and sanding heat-sensitive finishes or veneers where high RPM can burn the surface. For 80–120 grit rough sanding most users run flat-out, so a fixed-speed tool is fine. If you plan to polish, work with thin veneers, or sand plastics, prioritize variable speed.
Do I need dust extraction or is the included bag enough?
Across verified-purchase reviews and woodworking subreddits, the near-universal verdict is that onboard dust canisters and bags are mediocre at best. Hooking the sander to a shop vac (often via an adapter) dramatically improves dust capture, reduces airborne fines, and helps the abrasive last longer. Plan on a vac hookup for any serious indoor work.
What's a reasonable budget for a quality corded orbital sander?
Verified-purchase reviewers and Reddit tool threads consistently point to the $60–$90 range as the sweet spot for durable, low-vibration tools from established brands. Sub-$40 sanders work for occasional DIY but commenters flag shorter motor life and rougher vibration. Spending past $150 generally buys you premium dust extraction, a larger 6-inch pad, or pro-grade ergonomics.
