Things To Consider Before Buying Sanding Discs 

Here are some of the important factors that you should consider before investing in a sanding disc:

Your Needs 

Do you just need to sand the surface, or are you looking to calibrate the parts? What do the parts look like, and what are they made of? Do you require a particular surface targeted stock removal, surface finish, or both?

You should ask these questions in order to select the right kind of sanding disc for your project.

Adhesives

One Part Epoxy is one of the popular that many sand discs use. This material needs heat in order to get properly cured. Once it is cured, the adhesive generates a staunch bond with the surface.

The kind of adhesive a sanding disc determines the sturdiness you will get with the sander. A high-quality adhesive also ensures that you do not injure yourself during the process.

Types Of Sanding Discs 

Following are the types of discs available in the market –

Fiberglass

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.

Plastic 

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.

Metal 

 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.

Resin 

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.

Grain

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.
