Types of Grinder Sanding Discs
Grinder sanding discs come in various types, each designed for specific applications. Here are some of the most common types:

Choosing the Right Grit Level
The grit level of a sanding disc determines its coarseness or fineness. A higher grit number indicates a finer disc, while a lower grit number indicates a coarser disc. Here’s a guide to help you choose the right grit level for your project:
Grit Level | Use |

Coarse (40-60 grit) | Removing paint, rust, or heavy material buildup |
Medium (80-120 grit) | General sanding and finishing |
Fine (150-220 grit) | Finishing and smoothing surfaces |
Very Fine (240-320 grit) | Finishing and achieving a high-quality finish |
Size and Diameter
The size and diameter of a sanding disc are important factors to consider, as they determine the amount of material that can be sanded at once. Here are some common sizes and diameters:
- 4-inch: Suitable for small to medium-sized projects
