Orbital Sander vs. Random Orbit Sander

When choosing a sander for your DIY projects, you have the option to choose between a multi-sander, orbital sander and random orbit sander. But which is the right sander for the project at hand?


When hosting our DIY Divas workshops we touch on the topic of an Orbital sander versus a Random Orbit Sander and the difference between the two.

First off, it's important to note that it isn't the shape of the pad that gives the sander its name - but the motion of the sanding pad. An Orbital Sander generally has a rectangular pad but the pad rotates in a circular motion, which gives the sander it's name, whereas a Random Orbit Sander has a circular pad and also rotates in an orbit, but with an eccentric orbit. To put it simply, a Random Orbit Sander rotates off-centre, which means it never does the same surface area twice, and therefore reduces scratching on the surface of the material being sanded.





Which sander you use depends on the project you’re sanding. Understanding the main difference between an Orbital and Random Orbit Sander will ensure you’ve got the right sander for the job.

An Orbital Sander is ideal for sanding large surface areas and general sanding. A BIG plus when buying a Bosch PSS 200 AC Orbital Sander is the ability to use sandpaper instead of Velcro pads, which are featured on most Random Orbit Sanders. This model features a clamping system with a clamp lever for easy changing of sandpaper, and you will find tips on how to save money when sanding in this article.

As a finishing sander, and regardless of whether you want to sand or polish on wood, plastic, metal or painted surfaces - flat or curved surfaces - the Bosch PEX Random Orbit Sander ensures the finest finish and high sanding performance. Because this sander reduces scratching, it's ideal for polishing and finishing off your painted projects.
