Woodworking Sanding Discs

Sanding discs come in multiple forms and different among the following attributes:

  1. Material
  2. Backing
  3. Diameter Size
  4. Backup Pad Holes
  5. Required Backup Pad

For example, there are paper and cloth material that sanding discs are manufactured from. Paper is often used for types of sanding that load a disc (where the pores of the abrasives are smoothly filled with sanding debris, rendering the abrasive action ineffectual).
