Fibre disc

A fibre disc is an abrasive with rigid vulcanised fibre backing material, which is used with a back-up pad. They are primarily used for very high stock removal, e.g. when deburring or removing weld seams.

What effect does the use of a fibre disc have on service life, stock removal and surface?

• Stock removal: very high
• Service life: Depending on material, abrasive grain and additional layer
• Surface: fairly coarse, only limited suitability for finishing

Typical problems when using fibre discs:

• Overheating of the workpiece
• Wrong back-up pad
• Incorrect application

What needs to be kept in mind when using fibre discs?

• Use back-up pads with a suitable hardness
• Keep the pressure under control
• Use an angle grinder with sufficient power
