Buying Guide – Things You Must Consider Before Purchasing the Best Sanding Disc for Your Random Orbital Sander


You can’t just go into the shop and purchase sandpaper for your orbital sander. Because there is a massive chance of buying the wrong ones if you don’t have the idea about it. That’s why knowing the essential facts that make a regular sandpaper best for the orbital sanders. 

So, the things you must remember while purchasing the sandpaper or sanding disc are:

Grit Density of the Sanding Disc

Some orbital sandpaper grits cover 100% surface of the sander deck. On the other hand, some sandpaper grits come with the capability of covering 70-80% area of the deck. For the previous type, it is way easier for the sanding disc to get clogged after some days of usage.

But for the latter type, clogging and damaging are less likely to happen, which ensures an extended lifespan. At the same time, if you are sanding and polishing wood and other soft object surfaces, then the latter type of grits are more preferred. Therefore, while purchasing the orbital sanding discs, you must keep this fact in check.

Grit Grades of the Orbital Sanding Discs

Some orbital sandpapers have a vast range of gritting grades, and some have fixed grit. If you need to grind and polish objects from different surface types, it is crucial to have a vast gritting grade range. But some also want their sanding disc to come with a fixed grit.

In our list of the best sandpaper or sanding discs, we have both these types of sanding discs. So, before purchasing, all you need to do is determine which type you require and go for the one according to that.

Water Resistivity

Being water-resistive is such an essential part of the orbital sanding discs. Because you won’t always work on the dry surfaces, and sometimes, you will have to sand the wet objects. In such cases, the sandpaper will not be able to survive if it isn’t water-resistive.

That’s why an orbital sander that is capable of resisting water is a must in those conditions. Then you will be able to polish and sand those wet surfaces in the way you want. 

Attachment System of Orbital Sandpaper to the Sander

There are different attachment types of sanding discs or sandpaper to the sanding machine. If you are using a sandpaper sheet, you will have to attach it to the device with the help of a clip. But if you are using a PSA disc, you need to slap it on the backing pad of the random orbital sander.

On the other hand, the hook and loop attachment system is the best for the orbital sanders and sanding discs. Because of the tiny loops, the sanding disc will be appropriately attached to the backing pad of the sander. You just need to apply a bit of pressure on both ends to ensure a firm connection.

All the orbital sanding discs from our list come with the hook and loop attachment system. This attachment system is also crucial in removing and replacing the disc easily within a quick period. So, after purchasing a sanding disc among those, you won’t face difficulties during installation and replacement.

Keeping these factors in mind during the purchasing period will assist you in finding the best sandpaper for your best random orbital sander.

How to Attach Sandpaper in Random Orbital Sander

Attaching the sandpaper to the sander is the first task you need to perform in order to sand your metal or wooden object. But most people face difficulties in this phase if they are doing it for the first time. However, there is a proper method for pairing the right orbital sandpapers with the random orbital sander.

Improper application of that method will bring no success, let alone sand your objects. That’s why you need to follow the proper basic steps to attach the sandpaper to a random orbital sander. Those steps are: 

Step-1: Prepare your Sander and Sandpaper

The first thing you need to do is prepare your sandpaper and the random orbital sander. You will either use a circular sanding disc or just a sheet of sandpaper to pair. If it is a disc, there will be a “hook and loop” attachment system to connect with the sander.

As you will be using the random orbital sander, you need to find the perfect size of disc to fit your sander correctly. You also need to keep your focus on a certain number of holes in the disc. Because these holes are for fitting it correctly onto the sanding plate.

If your random orbital sander hasn’t been used for a long time, you also should clean it before attaching the sandpaper.

Step-2: Attach the Sandpaper to the Sander

If you are attaching a hook and loop sanding disc, you will first have to face your sander upside down. Then you will just have to place the tiny loop disc surface of the disc on the backing pad of your random orbital sander. In the end, apply pressure and press both the surfaces of the sander and sanding disc together.

You can also use a PSA sanding disc to pair with your random orbital sander. In that case, you again need to turn the disc upside down to reveal the backing pad, which should be facing up. There will be a paper or nylon liner will be attached behind the PSA sanding disc, and you need to peel that carefully.

After doing so, slap it on the sticky surface of the backing pad to pair it with the random orbital sander.
