Grinding Disc Backing Pad PRO for Angle Grinder, 22 mm Arbor Hole

Backing pad for grinding and sanding discs by PRO with a 22 mm arbor hole designed for use with compatible angle grinders. It serves as the interface between the grinding or sanding disc and the grinder spindle, providing a flat, stable mounting surface that helps maintain consistent contact with the workpiece during sanding, grinding and polishing operations on metal, wood and other materials.

Advantages

The PRO backing pad offers reliable disc support and low vibration transfer thanks to its robust construction. Its 22 mm central hole ensures precise alignment on grinders with compatible spindles, reducing wobble and improving surface finish consistency. The pad is designed for straightforward disc attachment and detachment, making disc changes efficient while maintaining firm retention during operation.

How to use

Mount the backing pad onto the angle grinder spindle, ensuring the 22 mm arbor hole is correctly seated and the pad is secured according to the grinder manufacturer’s instructions. Attach the appropriate sanding, grinding or polishing disc to the pad face, verifying that the disc matches the pad diameter and attachment system. Operate the grinder at recommended speeds for the chosen abrasive and material, applying even pressure and steady movements to achieve uniform results. Regularly inspect the pad and the disc for wear or damage and replace components when necessary.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and hearing protection when operating an angle grinder. Match disc type and grit to the task, and avoid excessive pressure or side loading on the backing pad to extend its service life. Confirm compatibility of the 22 mm arbor hole with your grinder spindle before use.
