Sebring Tip:

The 3M 20317 Random Orbital Sander is a departure from all the other tools we’ve covered in this article. This is a powerful pneumatic orbital sander, so it’s more suitable for professional or commercial use. Note also that you can only use it for applications where it will not produce dust.

It is heavier than most of the orbital sanders on the list because of its metal body. Make sure that you won’t be using it for several hours as it can result in fatigue.

Keep in mind also that this is more expensive than your regular orbital sanders.

Random Orbital Sander 101

Random orbital sanders are power tools used for smoothing, shaping, and polishing different types of materials. It can also be used to remove rust from metal, as well as for stock removal. You can use these tools on different materials, including wood, plastics, non-ferrous metals, and sheet steel.

A random orbital sander is just one of the many power sanders available for hobbyists, woodworkers, contractors, and other professionals right now. There’s the disc sander, belt sanders, detail sander, and drywall sander. Table sanders, orbital sanders, oscillating spindle sanders, and file sanders are also available for different applications.

But if you want versatility and excellent performance, then the random orbital sander definitely has a place in your garage or workshop. This handheld power tool’s design is similar to the regular orbital sander. But instead of a square pad, this particular power tool has a round pad.

The shape of the pad is just one of the differences between the random orbital sander and the regular orbital sander (also known as sheet sander or finish sander). With the regular orbital sander, you have to attach the sandpaper to the tool using built-in metal clamps. On the other hand, the sandpaper or sanding disc is attached to the random orbital sander using hook-and-loop (Velcro) or pressure-sensitive adhesive.

The sanding discs used by random orbital sanders are pre-cut to 5-inch or 6-inch in diameter. These special sandpapers generally come with holes in the middle which you have to align with the holes on your tool’s pad. The purpose of these holes is to draw the sawdust away from the work surface and into the dust canister or your shop vac, ensuring a cleaner and less toxic work area. But there are also some models that use sanding discs that do not come with holes (such as this 3M 20317 Random Orbital Sander).

So, why is this particular orbit sander described as “random.” The answer lies in the motion it produces. A regular orbital sander produces a simple back and forth motion while sanding. A random orbital sander, on the other hand, not only produces a back and forth motion, but also an unpredictable or eccentric circular motion while sanding.

Because the orbital or sheet sander simply moves back and forth, it is inevitable for it to leave visible marks on your workpiece. The random orbital sander, however, produces a more aggressive action and removes more stock from your workpiece.

But the good news is the finish it produces is smoother compared to the ones produced by sheet sanders. Plus, the resulting cross-grain scratches are a lot less visible compared to orbital/sheet sanders.

In addition, random orbital sanders also have variable-speed settings that allow you to control the aggressiveness of the sanding action.

But that doesn’t mean it doesn’t have its disadvantages. The sanding it produces is so aggressive that you have to be careful when leaving it in one area of your workpiece for a long time. And because it is rounded, getting in corners or sanding tight spaces is virtually impossible.

Check out this video for some tips on how to use your random orbital sander properly.

Random Orbital Buying Guide

Variable Speed

Random orbital sanders produce an aggressive sanding motion that can sand  away a lot of your workpiece if you’re not careful. That’s why it’s important to choose a tool with a variable speed setting. The general rule is the wider the range of speed, the better as this gives you more control when it comes to sanding.

Cordless or Corded?

If you’re working indoors and you have ready access to an electrical outlet, then it is best to go for a corded random orbital sander.

A portable cordless sander is the better choice if you’re going to work outside or your job site doesn’t have access to an electrical outlet. Sanders like these are powered by rechargeable lithium-ion batteries.

Although they have the advantage of being portable, you have to make sure that you’re not going to use the tool for several hours as their run time is limited.

The Right Type of Handle

Most random orbit sanders have a palm grip design. This allows you to grasp the top handle located directly on top of the pad and fully control the direction of the tool.

This design, on the whole, is ergonomic and keeps hand fatigue at a minimum. The problem is that some models have a bigger palm grip compared to others, making them difficult to grasp for people with smaller hands.

Palm sanders are ideal for smaller projects thanks to their compact and lightweight bodies. Apart from the palm grip, you can also hold them around the neck for greater control.

If you want greater control and a more secure grip, then check out random orbital sanders with D-handles. Some models even have the trigger switch located right below the handle for a more convenient operation.

If you want to reduce hand and arm fatigue while maintaining a firm grip on your tool, then check if the model has an auxiliary handle. A random orbital sander with an auxiliary handle is more convenient, and you can be assured that you can apply just the right amount of pressure to the tool while working.

It is also easier to use the tool vertically or overhead when it has an auxiliary handle. Some units have built-in auxiliary handles, while others have auxiliary handles that can be adjusted and removed when necessary.

Disk Diameter

Choose a 6-inch random orbital sander if you want to take on larger projects as it covers more area. But if you’re a hobbyist who tackles smaller projects or you want something lighter and budget-friendly, then go for 5-inch random orbital sanders.

The truth is every one of these random orbital sanders is outstanding in their own way. But, of course, there can only be one, and the best random orbital sander is…

Bosch GET75-6N Electric Orbital Sander

So, what makes it the most outstanding random orbital sander in the list?

What I like most about this 6-inch sander is its ergonomic design. I’m confident that all random orbital sanders in the list perform well and are durable, but you have to consider user comfort if it’s going to be a mainstay in your workshop and you have an extensive project that requires you to sand away at several workpieces for hours on end. 

There are a lot of options for handling the tool. There are the barrel and rubber-molded top handles. It also has an adjustable auxiliary handle that makes it easy to work on large surfaces or sand a vertical or overhead surface.

It has a pad guard that protects the front or side surface of your workpiece (in the case of cabinets or floors). It also has a longer dust exhaust port at the side which, for the most part, doesn’t get in the way.

It only has two-speed settings or sanding modes (normal and turbo mode), but it is still possible to get a finer finish when you set it to normal mode and an aggressive performance when you set it to turbo mode.

But it is heavy, so make sure that you consider that before buying this random orbital sander. It is also pricier than your regular random orbit sander. This might not be the ideal tool for you if you’re new to woodworking or you’re an occasional user.
