Question

which grinder accessory can be used to provide a stable surface for flexible sanding discs or buffing pads to rest against?
flap disc
arbor shield
backing pad
tool rest

Explanation:

• A flap disc is a type of abrasive disc used for grinding and sanding, not for providing a stable surface.
• An arbor shield is mainly for protecting the arbor area, not for supporting sanding discs or buffing pads.
• A backing pad is specifically designed to provide a stable surface for flexible sanding discs or buffing pads to attach to and rest against.
• A tool rest is used to support the workpiece during grinding, not for the discs or pads.

Answer:

backing pad
