6-inch PSA backup pad pack
The 3M 7000045680 PSA Disc Backup Pad is a round foam pad with a medium-density core and a tapered edge. It uses a pressure-sensitive adhesive surface to hold abrasive discs without a quick-change mechanism. The pad connects to the tool through a 5/16 in.-24 threaded shaft and is sold in a pack of 10 units.
3,000 RPM speed ceiling
The pad is rated for a maximum operating speed of 3,000 RPM, which sets a firm limit for the sander or grinder it is mounted on. Exceeding this speed risks pad failure or disc separation during operation. The non-vacuum design means no dust extraction ports are present, so the operator must manage debris separately.
Ten-pack capacity for production use
Each pack contains 10 pads, providing enough stock for extended body-shop work or multiple technicians. The 6 in. diameter covers standard repair areas, while the 3/4 in. thickness offers a stable backing for consistent pressure distribution. High-volume shops will need to reorder once the pack is depleted.

Questions about this item
Which capacity should I choose for the 3M 7000045680 backup pad?
This backup pad is sold as a pack of 10 units. Each pad measures 6 inches in diameter and 3/4 inch thick, so the pack quantity is the only capacity option available.
What does the 3,000 RPM maximum speed mean when the pad is mounted on a tool?
The 3,000 RPM rating is the highest safe operating speed for the foam pad. Running your sander or polisher faster than this limit risks pad failure or separation from the backing.
How does the 5/16 In. -24 threaded shaft affect which machines I can use?
The pad fits any rotary or orbital tool that accepts a 5/16 In. -24 threaded shaft. It will not mount on tools with different thread sizes or quick-change collets without an adapter.
