Quick-Change Backup Pad

This 3M 45101 backup pad accepts quick-change abrasive discs using the TR mounting system. A 1/4 in.-20 threaded hole secures the pad to compatible sanders. Medium-density rubber construction supports a maximum operating speed of 30,000 RPM for material removal tasks.

Professional and DIY sanding jobs

Suited for operators who need fast disc changes on a 1 in. round pad without vacuum extraction. Not intended for users who require dust-collection holes, larger pad diameters or alternative mounting patterns such as hook-and-loop.

30,000 RPM maximum speed

The rated 30,000 RPM limit determines whether the pad matches the sander’s output. Exceeding this speed risks pad failure, so verify the tool’s free-speed rating before fitting the 45101.

Questions about this item

How long can the 30,000 RPM backup pad run before the rubber reaches its thermal limit?

The medium-density rubber pad is rated for continuous operation at 30,000 RPM; heat buildup depends on the sander motor and disc friction, so monitor the housing temperature during extended use.

What is the noise and vibration level when the pad spins at 30,000 RPM all day?

3M does not publish a decibel or vibration figure for the 45101; expect typical high-speed sander whine and transmit vibration through the 1/4-20 threaded connection to the tool.

Which sander spindle does the 1/4-20 threaded hole fit without an adapter?

The pad mounts directly on any sander with a 1/4 in.-20 male threaded spindle; no additional hardware is required if the tool matches that specification.
