MY TOP PICK:
If you are looking for the best overall, I recommend theDEWALT DCW210Bbecause it features variable speed control for a range of projects and a low-profile design for getting into tight spaces.


What is a random orbit sander?

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.

How does it work?

This tool is different from a standardbelt sanderin 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.

If you are just getting started, check out this brief video that covers some of the basic features and provides a demonstation of this type of sander:

Disks

Random orbital sanders use sandpaper disks that are attached using either pressure-sensitive adhesives or a hook and loop system. This allows the disks to be quickly replaced or swapped out for a different grit.

Dust Collection

On models equipped with a dust collection feature, a vacuum sucks discharged dust through holes in the disk, feeding it to a bag,shop vac, or filter canister. The simple dust bag option is usually the most affordable choice but it is not the most effective method of dust mitigation.

Many sanders allow for a shop vac to be connected which greatly enhances the dust collection but it can be cumbersome to work with a hose attachment. The best of both words are the filter canisters that collect and contain the dust while allowing for maximum maneuverability. However, this does come at a cost premium.

Orbits Per Minute

Some models offer variable speeds which allow you to control the Orbits Per Minute (OPM) within a specified range. The OPMs will vary by manufacturer but typically fall in the 5,000 to 14,000 range. Obviously, the higher the number the more material will be removed in the same time period.

Variable Speed

根据模型,大多数这些工具variable speed that is typically controlled through a dial on the side of the unit. This allows for greater flexibility when working on a range of applications and woodworking projects.

Corded vs. Cordless

As with most power tools today the same pros and cons apply when comparing the corded and cordless models. Corded have the advantage of never running low on power but lack the freedom and maneuvering that cordless sanders offer.

Cordless offers the benefit of complete freedom while working but can limit the work time based on the charge and number of batteries you have. In addition, cordless is usually a more expensive option when compared to corded sanders. Based on your projects and way of working, you will need to determine what is the best power method for your situation.

Also, if you already have other cordless tools you may want to pair the sander with the same brand so they can share battery packs.Check to make sure it is indeed the same battery, as it can differ even within the same brand.

Weight

Since you are often holding these tools at awkward positions it is important to note the weight, as working with a heavy tool can quickly cause fatigue. For cordless options, the weight provided by the manufacturer will oftenexclude the battery weight.So take into consideration the additional weight of the battery you will be using. Keep in mind that typically a higher voltage battery does mean a longer run time but at an increased weight.

The following random orbital sanders are excellent for many types of finish work and can be used in conjunction with, for example, anelectric hand planerto get the desired wood surface.

So here is my list of The Best Random Orbital Sanders for 2021.
