Most random orbit sanders cost $40 to $80 and do an adequate job. These two cost more and do a better job. The Festool ETS 125 REQ is a corded 5-inch sander from the brand that professional finishers worship. The DeWalt DCW210B is a cordless brushless unit that runs on 20V MAX. The Festool extracts dust like nothing else on the market. The DeWalt gives you freedom from a cord. Different priorities.
Quick Verdict
The Festool ETS 125 REQ produces a measurably better finish. The smaller orbit diameter and superior dust extraction make it the right sander for fine furniture, cabinet finishing, and any work where the surface will receive a clear coat. The DeWalt DCW210B is the right sander for everything else: jobsite trim finishing, paint prep, deck refinishing, and any sanding where a cord is impractical. At less than half the price, it's the better general-purpose sander.
1/8-inch orbit leaves no visible swirl pattern under clear finishes. Dust extraction keeps the grain clean between coats.
Cordless operation is mandatory on jobsites where outlets are scarce. Pad brake prevents swirl marks.
99% dust capture means you're not breathing sanding dust in an enclosed kitchen all day.
No cord, no dust extractor to haul outside. Dust management doesn't matter outdoors.

Festool ETS 125 REQ
Price: $250 (Amazon)
Pros
- Dust extraction with a Festool CT captures 99%+ of sanding dust, leaving surfaces and lungs clean
- 1/8-inch orbit diameter produces the finest swirl-free finish of any random orbit sander
- Variable speed from 6,000 to 12,000 OPM with soft-start prevents pad marks on delicate veneers
Cons
- $250 for a sander is hard to justify unless finishing is your primary trade
- Corded operation limits mobility and requires a dust extractor for best results
- Proprietary Festool sanding pads and discs cost 2 to 3x more than standard hook-and-loop
DeWalt DCW210B
Price: $99 (Home Depot)
Pros
- Cordless freedom lets you sand anywhere without extension cords or dust extractor hoses
- Electronic pad brake stops the pad when lifted, preventing swirl marks on set-down
- $99 bare tool is strong value for a brushless cordless sander
Cons
- 5/32-inch orbit is more aggressive than the Festool, harder to get a swirl-free finish on clear-coat work
- Dust bag captures maybe 70% of dust, nowhere near the Festool's extraction performance
- Battery adds weight and shifts the balance point slightly compared to the lighter Festool

Frequently Asked Questions
What does orbit diameter actually affect?
Smaller orbit (1/8 inch) means finer scratches and a smoother finish but slower material removal. Larger orbit (5/32 to 3/16 inch) removes material faster but leaves more visible swirl patterns. For bare-wood finishing under clear coat, smaller is better. For paint prep and heavy stock removal, larger is faster.
Do I need a Festool dust extractor to use the ETS 125?
Not technically. It has a standard dust port that connects to any shop vac with a hose adapter. But Festool CT extractors use auto-start (the sander turns on the vac automatically) and HEPA filtration. The ETS 125 performs best in the Festool ecosystem. Without it, you lose the signature dust extraction advantage.
Can I use third-party sanding discs on the Festool?
Yes, any 5-inch hook-and-loop disc fits. Third-party discs from Mirka, Diablo, and 3M work fine. Festool's own Granat discs last longer and cut more consistently, but at $30+ per box of 50 versus $10 to $15 for third-party, many users compromise.
