Understanding Sanding Discs

Sanding discs come in various sizes, materials, and grit levels, making them suitable for different tasks. Common materials include aluminum oxide, silicon carbide, and ceramic. Each material serves a specific purpose:

  • Aluminum Oxide: Ideal for general woodworking and metalworking, these discs are durable and suitable for both rough and fine sanding.
  • Silicon Carbide: Best for sanding harder materials like glass and plastic, these discs provide a sharper cut but wear out faster.
  • Ceramic: Perfect for heavy-duty applications, ceramic discs are excellent for removing material quickly and can withstand high temperatures.

Choosing the Right Grit Level

The grit number of a sanding disc indicates its coarseness or fineness. A lower grit number, such as 40 or 60, is used for coarse sanding, while higher numbers like 120 to 400 are for finer finishes. Here’s a quick guide on when to use different grit levels:
