Quick Answer: The Bosch GEX125 random orbital sander delivers the smoothest furniture finishes we have tested, with its micro-filtration dust system keeping your workspace clean and your lungs protected. For furniture refinishing, swirl-free sanding is everything, and this sander’s tight orbit pattern produces results that impress even professional finishers.
What to Look For
Furniture refinishing prioritizes finish quality above removal speed. Random orbital sanders spin and oscillate simultaneously, creating a swirl-free scratch pattern that disappears under finish. The orbit diameter affects aggressiveness: smaller orbits (1/16 inch) produce finer finishes while larger orbits (3/16 inch) remove material faster. Variable speed is essential for working through grits, running slower for fine sanding to prevent heat buildup. Dust collection quality directly affects finish quality since airborne particles settle on wet finish coats. Vibration levels determine how long you can sand comfortably. Pad size (5-inch or 6-inch) and hook-and-loop disc attachment make grit changes fast. Consider a corded model for all-day refinishing since battery weight and runtime limitations add up over hours of continuous sanding.

How to Choose
Workshop-based refinishers should choose the Bosch GEX125 for its superior finish quality and dust collection when connected to a shop vac. If you refinish furniture on-site or in different locations, the DeWalt DCW210B gives you cordless freedom without sacrificing much finish quality. The Makita XOB01Z is ideal for LXT platform owners who want a versatile sander for both furniture and general woodworking. Always sand through progressively finer grits (80, 120, 180, 220) and never skip more than one grit level. Connect to a dust collector or shop vacuum for the best results regardless of which sander you choose.
FAQ
Random orbital vs sheet sander for furniture?
Random orbital sanders produce swirl-free finishes and are superior for furniture refinishing in almost every scenario. Sheet sanders (1/4 or 1/3 sheet) are useful only for flat surfaces with straight-grain sanding or for getting into tight corners where a round pad cannot reach.
What grit progression for stripping furniture?
Start with 80 grit to remove old finish and smooth major imperfections. Move to 120 grit to refine the surface, then 180 grit for pre-finish smoothing. Finish with 220 grit for most stains and polyurethane. Water-based finishes may need 320 grit for glass-smooth results.
How do I avoid swirl marks?
Let the sander do the work without pressing down. Move slowly across the surface. Use lower speeds for finer grits. Never start or stop the sander while it is in contact with the wood. Replace worn sanding discs promptly since worn discs create more heat and more swirls.
