Best Random Orbital Sanders for Refinishing Furniture
Direct answer. The Makita BO5041K is our top pick for most furniture refinishing. Its variable speed goes down to 4,000 OPM, which lets you sand gently on veneer and turn it up to strip old finish, and the pad brake helps prevent swirl marks. For cordless work, the Milwaukee 2648-20 is the pick, and for simple cordless jobs the Ryobi PCL406B is the easiest sander in this set to pick up and use.
Refinishing furniture is mostly about the sanding sequence, not the sander alone. A random orbit sander removes old finish fast and leaves a smooth surface, but only if you work through the grits in order and keep the pad flat. A variable speed dial helps, since low speed suits veneer and fine finishing, and high speed suits stripping. Sanding dust is a health risk, so wear a dust mask and eye protection, connect the sander to a dust bag or vacuum, and never sand lead based paint without following the proper precautions in the maker manual. Empty the dust bag often, since fine sanding dust can build up heat.

How we research
We compared specs, maker data and owner reviews for 5 random orbit sanders. Amazon US listings for all 5 products could not be confirmed on 2026-11-06, so each product shows ASIN_TBD rather than a guessed ASIN. Our criteria were finish quality and swirl control at 30 percent, speed range and control at 25 percent, dust collection at 20 percent, comfort and vibration at 15 percent, and pad and paper compatibility at 10 percent. Sources were maker pages and maker manuals, checked on 2026-11-06. We did not pick any model based on what it costs at Amazon.
Makita 5 in. Random Orbit Sander with Variable Speed BO5041K
Best for most furniture refinishing, especially pieces with veneer and old finish that need both gentle and aggressive sanding.
Key specs are a 5 in. abrasive disc on a 4-13/16 in. pad, variable speed from 4,000 to 12,000 OPM, an orbit diameter of 1/8 in., and a 3 amp corded motor. It weighs 3.5 lbs. Dust collection runs through the pad, with a high capacity system and a built in vacuum port adapter. The kit includes the sander, a dust bag, a dust bag nozzle, and a tool case. It has an adjustable front handle, a rubberized palm grip, and a pad control and brake system.
Pros:

Con: At 3.5 lbs it is the heaviest sander in this set, so long sanding sessions on large furniture take more effort.
Owner review themes point to owners who praise the low speed range, the smooth finish, and the dust collection when connected to a vacuum. Complaints focus on the weight, the size of the sander on small pieces, and the cost of the kit compared with smaller sanders.

Check current price on AmazonQuestions to ask before buying
What grit sequence should you use to refinish furniture with a random orbit sander?
Start coarse enough to remove the old finish, then work up in steps. A common sequence is 80 grit to strip, 120 grit to smooth, 180 grit to prepare for finish, and 220 grit for the final pass before stain or topcoat. Do not skip grits, since each step removes the scratches from the last one. If you skip from 80 to 220, the deep 80 grit scratches will show through the finish. Vacuum or wipe the piece between grits so old grit does not scratch the surface.
How do you avoid swirl marks when sanding furniture?
Keep the pad flat on the work and move the sander slowly in overlapping passes. Do not press hard, since pressure makes the pad dig in and leaves swirls. Let the sander stop fully before you lift it, and use the pad brake if your sander has one. Work through the grits in order, since a coarse scratch left behind will look like a swirl under finish. The Makita, Milwaukee, and Bosch sanders in this set have pad brakes that help.
Should you sand with the grain or in circles with a random orbit sander?
A random orbit sander moves in small circles, so you do not need to follow the grain the way you do with hand sanding. Move the sander slowly across the piece in overlapping passes, and finish with a light hand sanding pass along the grain with the final grit. Hand sanding along the grain at the end removes any faint circular marks and leaves the surface ready for finish.
How do you sand through old finish without damaging the wood underneath?
Start with a coarse grit and a low speed, and check the surface often. Once the old finish is gone, switch to a finer grit right away, since a coarse disc will cut into the wood fast. On veneer, use the lowest speed and the finest grit you can, and stop as soon as the finish is off. The Makita in this set goes down to 4,000 OPM, which suits veneer. If the veneer is thin or damaged, hand sand it instead of using a power sander.
Corded or cordless random orbit sander for furniture refinishing?
Corded suits long sanding sessions and large pieces, since power never fades and the sander stays light. The Makita, DeWalt, and Bosch sanders in this set are corded. Cordless suits quick jobs, small pieces, and work away from an outlet. The Milwaukee and Ryobi sanders in this set are cordless. For a full piece of furniture with several grits, corded is simpler, since you never stop to swap batteries. For a chair or a small table, cordless is fine.
Frequently asked questions
Can a random orbit sander remove old paint and varnish?
Yes, with a coarse grit. Start with 60 or 80 grit to cut through the old finish, then work up through finer grits. Wear a dust mask and eye protection, and check whether the old finish could contain lead paint before you sand it. Do not sand lead based paint without following the proper precautions in the maker manual.
What size sanding discs does a 5 in. random orbit sander take?
A 5 in. random orbit sander takes 5 in. hook-and-loop discs with 8 holes for dust extraction. The holes must line up with the pad for the dust collection to work. All five sanders in this set use 5 in. discs, so paper is easy to find.
How do I keep dust out of the finish when sanding furniture?
Connect the sander to a dust bag or vacuum, and vacuum the piece between grits. Wipe the surface with a tack cloth or a damp cloth before you apply finish, and let it dry fully. Sand in a clean area away from other dusty work, and keep the piece covered while the finish dries.
Do I need a vacuum or is the dust bag enough?
A dust bag catches most of the dust and is enough for small jobs. A vacuum connected through the dust port or hose adapter catches far more fine dust and keeps the air cleaner, which matters on large pieces and in a closed shop. The Milwaukee and Bosch sanders in this set include hose adapters, and the Makita has a vacuum port adapter.
When should I switch from a random orbit sander to hand sanding?
Switch to hand sanding for the final pass, for edges and corners the round pad cannot reach, and for thin veneer that a power sander could cut through. Hand sand along the grain with the final grit, using a sanding block to keep the surface flat.
