I refinished a butcher-block island top, a cedar deck rail, and three solid-core doors over six weeks while testing five random orbit sanders. Here is what survived the dust.
What Matters Most
Low vibration matters most for hand fatigue. Effective dust collection keeps your shop and lungs clean, and hook-and-loop pads need to grip after a hundred swaps.
My Setup
I ran each sander through the same 80-to-220 grit progression on identical pine boards, then on my real projects. I measured RPM, weighed dust caught, and timed pad changes.
The Sanders I Tested
The Festool ETS 125 REQ Random Orbital Sander was the smoothest and fastest. Hooked to a dust extractor, it captured 98 percent of the dust and left no swirls.
The DEWALT DWE6423K 5-Inch Random Orbit Sander is the contractor classic. Affordable, durable, and the rubber overmold reduces fatigue.
The Makita BO5041 5-Inch Random Orbit Sander has variable speed and the cleanest power delivery. Best pick for delicate veneer work.
The Bosch ROS20VSC 5-Inch Palm Sander is the budget pick that punches above its price. The bag dust collection is acceptable, the vacuum port is excellent.
The Milwaukee M18 FUEL 5-Inch Random Orbit Sander is my cordless pick. Battery life on a 5Ah pack held for a full door front.
Common Mistakes
Pressing harder slows the orbit and burns spirals into your finish. Let the sander float. Skipping grits leaves scratch patterns the stain reveals later. Always hook to a vacuum on hardwoods.
Final Recommendation
The DEWALT DWE6423K is the best buy for most woodworkers because it nails the price-to-performance balance. For a forever sander, the Festool ETS 125 REQ is genuinely worth the upgrade.
Frequently asked questions
What grit progression should I use?+
For raw wood I run 80, 120, 180, then 220. Skipping grits is the number one cause of swirl marks the next morning.
Corded or cordless orbital sander?+
Corded for long furniture refinish sessions. Cordless for trim and quick spot work. I keep one of each on the bench.
