Sanding discs can come in a variety of shapes, sizes and materials. Knowing the right type of sanding disc to use in your project will make sanding easier and help you to achieve the best results. Ask yourself a few questions when selecting the right sanding disc for you.
1. What Material Are You Sanding?
First, consider the material you are sanding. Sanding discs made of aluminum oxide are suitable for most types of wood, fiberglass or metal. Silicon carbide discs are more suitable for softer materials such as plastic or aluminum. For non-ferrous metals, such as brass, copper and bronze, it is best to use abrasive paper.
2. What Grit Level Do You Need?
The grit of a sanding disc will determine the aggressiveness of the sanding. The lower the grit, the more aggressive the sanding. Coarser grits, such as 36-60, are best used for heavy sanding and removing old finishes. Finer grits, such as 80-220, are best used for light sanding and finishing.
3. What Size and Shape Do You Need?
The size and shape of sanding discs are important when selecting the right one for your project. Sanding discs come in a variety of diameters ranging from 4” to 7”. They can be in either circular or rectangular shapes. Sanding discs that are small and dense are better for tight areas or corners, while larger discs are better for larger, flat surfaces.
4. Which Brand Do You Prefer?
When selecting a brand of sanding discs, consider one that has a good reputation for performance and durability. Popular sanding disc brands include 3M, Mirka, Norton, and Yale.
To sum it up, the key to choosing the right sanding disc for you is to consider the materials you are sanding, the grit level, the size and shape you need, and the brand you prefer. With the right sanding disc, you can achieve optimal results with your project and save time.
