Essential Facts in Choosing the Best Disc Sander

It is never wise to go for a product without seeing what kind of ideal features disc sanders come with. These important factors will give you a fine aspect of what you are looking for. If you are an amateur, this section is a must for you.


Availability of Both Disc & Belt Sanders

We are discussing the best disc sanders here, but often these days’ disc sanders include a 2 in 1 feature of having both disc sanders & belt sanders. You can save a lot of workspaces as you can work with both the tools than buying them separately. Having this feature will benefit you a lot.

Disc Size

The disc size of a sander usually ranges between 5 to 8 inches. The numbers can go up to 10 or even 12 inches too. This size depends solely on the type of project you are working on. If you are working on large projects, then you will need a larger disc.

Because the more surface area of the disc means the lesser time you will need sand.


The performance of the sander depends on the power the motor provides. The more powerful the motor is; the more work you can get done by it. The power rating is measured by the Amps & the horsepower of the motor. If you are working with a large amount of sanding tasks, then go for a powerful motor.


Disc speed & belt speed is an important factor to keep in mind. These are measured in RPM. The usual range of disc speed is 1200-4000 RPM. Speed is important because you will need various speed ranges for different types of wood.

Hardwoods require lower speed while softwoods can work with higher speeds. The same goes for belt speed too.

Rotating Angle

The flexibility & rotation of the belt sanders is adjustable. The adjustable disc tables will give you a tilt angle of 0 to 45 degrees & 0 to 90 degrees. This way you can work both horizontally & vertically & perform all your custom sanding actions with ease.

Dust Collecting Port

Disc Sander produces a lot of dust making your workspace a mess. A few minutes of work & you will see the whole place covered with dust. That’s why the top valued disc sander has one or more dust collecting ports.

These ports vacuum out the dust as the sander runs, keeping your workspace debris free. Having dust collection ports on your disc sander comes in very handy.


Q: Can I sand Glass using a Disc Sander?

Ans: Technically it is not advised to sand glass with a disc sander. Glass is a very delicate piece of material. With little movement going wrong, the whole glass would be wasted. There are a lot of other tools such as Dremel, drills to sand glass. Even the sandpaper used to sand glass needs a lot of modifications.

Q: What direction should I use the belt sander?

Ans: Belt sanders are used to level a surface neatly. So you need to keep the belt of the sandpaper in level with the surface you are working on. You have to be careful while working with edges as if you tilt the belt even a bit, it will ruin the edge.

Q: Are there any safety measures while using a disc sander?

Ans: Yes, working with a disc sander can become dangerous, if you have not taken any safety measures. There is a lot of scattering of small parts while sanding, so you have to have safety goggles for the protection of your eyes.

Your hands must also be kept as far away as possible from the rotating disk. Even with a minimum amount of contact, it can peel your upper skin. So be careful while working with them.

Q: Can the vibration of the belt sander be reduced?

Ans: If you are working with delicate woodwork, then the vibrations of sanders can become annoying. You can mount a rubber pad underneath the sander. This will tackle some of the vibrations for you. But you will still have some vibrations as it works on a motor. 

Q: What type of grit should I use?

Ans: The grit of the sandpapers depends on the work you are doing. If you are looking to do heavy sanding jobs, then a lower grit of around 60 is recommended. But for polishing work, it is ideal to use a grit between 100 to 200. This grit is recommended for wood only.
