For this post, I have put together a collection of the best random orbital sanders currently available.
UPDATED: September 12, 2019.
MY TOP PICK:
If you are looking for the best overall, I recommend the Bosch ROS65VC-6 because it features a vibration reduction system to minimize hand fatigue and a microfilter canister for trapping dust.
Random orbit sanders are hand-held power tools for sanding in which the sanding blade delivers a random-orbit action. That is, the angle of rotation of the head and disk is variable.
This tool is different from a standard belt sander in that the random orbit sanding pattern is produced by simultaneously spinning the sanding disk and moving it in small ellipses. This ensures that no single part of the abrasive material travels the same path twice during the same rotation. Because of this random sanding action, the tool does not leave swirl marks, and is not sensitive to the direction of the wood grain. This makes it useful when sanding two pieces of wood that will be fastened at right angles.
Random orbital sanders use sandpaper disks, and many include integrated dust collectors. Disks are attached using either pressure-sensitive adhesives or a hook and loop system. On models equipped with a dust collection feature, a vacuum sucks discharged dust through holes in the paper and pad, feeding it to a bag, shop vac, or canister.
The following random orbital sanders are versatile tools that are excellent for many types of finish work and can be used in conjunction with, for example, an electric hand planer to get the desired wood surface.
So here is my list of The 10 Best Random Orbital Sanders.
