Types Of Sanding Discs

Following are the types of discs available in the market:


These are the most popular types of discs you will find in the sanding machine. Fiberglass is reckoned because of the durability, safety, and strength they offer. These types of discs work strongly with different kinds of adhesive. And one of the best parts is that fiberglass will not contaminate your working surface.


This type of material is also widely used, particularly in the European region. One of the benefits of plastic materials is that they can be trimmed in order to increase the application of abrasive materials. Moreover, plastic discs come in a wide range of colors, so you can choose the one that best matches your sanding machines.

Arbor holes in the plastic material can be added internally to the backing. However, one of the downsides of plastic is that it can contaminate your working area.


If safety is your concern, then the metal is the option you should consider. The sanding discs that are made using metal backing offer more aggressiveness. One of the valuable benefits of metal is that it does not require any backing flange. However, these are also the most expensive options.

Abrasive Backing

It has to be one of the most important aspects; however, it is frequently overlooked. The backing needs to be strong in order to retain the grain from wearing before time.

However, it should not be too strong in order to result in glazing on the disc surface. The most popularly used backings are poly-cotton, X weight cotton, and polyester backings.


It is used to bond the abrasive backing and grain. Generally, there are two resin coats; however, there are certain cases where the third coat is applied in order to enhance the performance, reduced loading, and cooler grinding.


The type of grain you select depends on the application. Zirconium is the common material used in the grain because of its price against the performance ratio. Moreover, it also offers great compatibility with different forms of metals.

What To Consider Before Buying A Sanding Disc

When selecting a sanding disc for your tasks, there are numerous factors to consider. What remains the best part? For a very low price, you may acquire a robust and high-quality sanding disc. Some depend on the material, while others are focused on the features.

Solid Foundation

Always check to see if the sanding disk you are choosing has enough stability to hold it in place while you work. In fact, this feature not only ensures a pleasant working experience but can also save your fingertips from the tool’s business end. Balance this against the task you plan to do and the location of the machine.

Metal Construction

If at all feasible, look for tools that are made entirely of metal or that employ as much metal as possible. While plastic has gone a long way, when it comes to stiffness and longevity, metal still reigns supreme. This feature will have a significant impact on the price, but it will ensure that you have the sander for a long period.

Tilt Function

You may use the tilt option to conduct angular sanding. Through this, a smooth and polished finish is achieved with complete control. There is also an option of grinding portions away from the tool’s tilting surface. However, it should be kept in mind that doing so limits your ability to sand precisely and safely.

  • Whenever using sanding discs it is very important to wear appropriate PPE (Personal Protective Equipment).
  • Sanding and grinding release very small particles into the air, some that can be very dangerous when inhaled. Make sure to wear a respirator and have good ventilation.
  • Let the disc do the work and don’t apply too much pressure
  • Sanding discs, attachments like backing pads and the actual tool are all rated for different RPMs. It’s important to verify all of your equipment works within the same RPM ranges.
  • To get the most out of your sanding disc, ensure it is properly cleaned after each use. This can be done with a sanding disc cleaning stick.
