What is a disc sander?

A disc sander is a machine for sanding or polishing that is equipped with a disc that performs a round oscillating movement parallel to the work surface. This is a tool for the removal of a surface from a certain material with the abrasive medium. When purchasing a disc sander, it is important to make sure that it has an efficient system for dust suction. This system, besides efficiency, should contain appropriate filters that will hold even the finest dust particles. It is also useful to purchase additions that can enable the disc sander to attach to a vacuuming system you already own in your garage.

The poorest solution (but often the only one) is to rely on a bag attached directly to the sander and the ability of a built-in vent to blow dust into the bag. Unless you have previous experience with electric disc sanders and want to get one, consider the fact that based on the housing, there are three basic types of sanders:

Palm grip
Right angle
Pistol grip

The popular combo kits aren’t usually ones to include disc sanders. You may also be interested in our best belt sanders article to add a sidekick to your disc sander. We do recommend being equipped with all types of tools if you want a full arsenal — Reddit’s belt sander vs. disc sander article also agrees.

How to choose which disc sander to buy

Your budget – This will really dictate which direction go when choosing a disc sander. The higher you go, the more additional features, overall quality and longevity you will get.
Brand preference? We all know those “DeWalt-only” or “Makita or bust” tool enthusiasts. With power tools, brand is at least something to take into consideration when it comes to investing.
Diameter – The diameter of your sander is something to take into consideration. Do you have a larger surface to take care of? Only small projects? They range from about 4″ to 12″. In this instance, yes in a way — the bigger the better (only if you need to tackle a bigger surface area in the future). However, this doesn’t necessarily imply that you have to go insanely big. The average is around 6 inches,and the higher you go the better the quality, quickness and accuracy the sanding will be.
Overall style of build – Handheld, with a stand, or other? There’s a time for each, and this all depends on what type of jobs you expect yourself to need to use the sander for, or what it will entail in the future. We found a few of each category to fit all readers.
Additional features? Corded or cordless? Some also come with cleaning systems, others the stands as spoken previously, fancy handles, measuring systems and some with diameter choices. It all comes down to how much you want with your tool.
