Buying Guides

Someone who is the first time to learn about tools might be confused about an orbital sander and a random orbital sander. In fact, they are two different tools, and the main difference is the way they move.

In an orbital sander, the disc spins around a circle. That’s the only way it moves.

In a random orbital sander, the disc spins in a circle and oscillates around. This way keeps the pattern after sanding more random and will eliminate any visible scratches and creating a smoother finish.

So, if you are looking for a random orbital sander, there are some useful tips you should keep in mind before making your decision:

Motor and OPM

The motors range usually vary from about 2 – 6 AMP to operate the sander. Two sanders with the same AMP don’t mean they have the same performance. The matter is how effectively they use the power they have.

OPM - stands for orbits per minute - will help you know how fast the sanding disc rotates. The higher the number, the faster the sanding disc spins.

Some sanders are single speed and only working at the high range. Others have a variable speed that allows them to work at different speed depending on your projects.

Power Source

Random orbital sanders typically have three different types of power sources: corded, cordless (battery operated), and pneumatic.

The pneumatically powered sanders are powerful, but they require an air compressor to operate. Professionals usually use them, so in my review, I only mention about corded and battery operated ones (this is the lack in my review).

The power source affects sanders weight, power, and reliability.

Corded random orbital sanders have more power and are more reliable. You will don't need to worry about how much the battery remains. But the pros of this type is cumbersome and get in the way when you’re working.

Battery operated random orbital sanders are flexible, but you must make sure that the battery is always enough for your projects.

Base Plate

The sandpaper is attached to the base plate. So we should notice it choosing the new random orbital sander:

First, this part will determine the sanding area. Random orbital sanders usually come in two sizes, 5 or 6 inches. Anything smaller than 5 inches is called a finishing sander, and other is a professional tool powered with an air compressor.

Another notice is how you attach the sanding discs.

Some sanders use adhesive discs to attach them on the plate, but they are unreliable because they can wear, and come off when the sander is working.

Others are moving toward a hook and loop system to attach the sanding paper. It is more reliable and easier to do.

The next thing is the holes where the sawdust will be sucked up by the dust removal system when working. It keeps the sawdust off the wood surfaces to avoid any tiny scratches.

The covering foam of the base plate will wear during the working time and need to replace. This means either replace the foam itself or the entire sander. Keep in your mind when comparing other products. If you decide to invest an expensive sander, you might want to make sure the pads are replaceable.

Dust Collection Systems

The almost self-contained dust collection system of the sanders in the market can be modified to a vacuum collection system. You can remove the bag of the dust collection system to attach a vacuum hose to the sander for added suction and efficiency.

But, at first, you should check the size of the dust collection port. Make sure that they can be connected together if not you will need to find an adapter for connecting.

FAQs - Frequently asked questions


When to use variable speed on an orbital sander?

You can set the sanding speed to depend on your project. Low speed is ideal when you are working with flat surfaces and high speed when you want to sand down faster.

A higher sanding speed isn’t always better in practice. Low speed is preferable to sand a painted surface, for example. Because this will prevent the paint from getting hot and spreading out or clogging up the sanding sheet. You will, therefore, have to think about the optimal sanding speed for each specific job.

How to get the best sanding results?

  • The quality of sanding depends on various factors. It is always necessary to replace the new sanding sheets in a proper time.
  • Never use the same sanding sheet for both wood and metal.
  • You must choose the right grain size for your material for the best result.
  • Do not apply too much pressure when sanding. The sanding sheet will wear faster, and the results will be less good.
  • Try to get the best sanding speed on a piece of waste material before sanding with the right speed on your job.

What sandpaper grit to use for my random orbital sander?

  • It depends on your stage.
  • If you want to remove material quickly, you should choose the lower grit.
  • For the best result in finishing, you should choose the higher grit number.

Can you use a random orbital sander as a polisher/waxer?

Sanders are for sanding. So unless want to sand your vehicle, it is not the appropriate tool to use.

I know you want to trim your budget when buying the new orbital sander. But you're aiming out of a reasonable league with wanting to use the wrong tools which could damage your vehicle.

What to do when orbital sanding pads loses adhesive?

When the pads have a lot of dust, it loses its grip and does not stick. So what to do? Clean and reuse.
