Choosing the Right Flap Disc Material

The construction of a Flap Disc consists of multiple abrasive sheets (flaps) around the centre ring. These flaps are made from a number of materials that can differ depending on the application requirements.

When choosing the right type of Flap Disc to use for your project, it is important to note that the abrasive grain material used in the disc greatly impacts its performance, durability and suitability. The most common types of abrasive materials used with Flap Discs are:

  • Aluminium Oxide
  • Zirconium
  • Ceramic

  • To get a better understanding of the options for the types of abrasive materials used in Flap Discs, it is best to be aware of the features, applications, and benefits of the different materials available.
