2-inch Quick Change Backup Pad

This 3M 45095 backup pad accepts quick-change abrasive discs on a TR mounting system. The 2-inch rubber pad has a medium density and a threaded 1/4-20 hole for direct attachment to compatible die grinders. It is built for non-vacuum sanding applications where fast disc changes are required.

Upgrade from screw-on or adhesive discs

The TR quick-change interface replaces slower screw-on or adhesive-backed disc systems. The jump is worth it when operators need to swap grits in seconds without tools during multi-step finishing work. It suits technicians who value changeover speed over vacuum dust extraction.

Medium-density rubber at 25000 RPM

The medium-density rubber construction maintains consistent contact on contours while resisting heat buildup during extended runs. Rated for 25000 RPM maximum operating speed, it delivers stable backing for prolonged material removal without the pad softening or deforming under sustained load.

Questions about this item

What thread size does the 2-inch backup pad use for the 1/4-20 connector?

The pad has a threaded 1/4-20 hole that screws directly onto the matching spindle of a quick-change disc sander.

How do you attach a disc to the TR quick-change system without cross-threading?

Align the disc's TR fastener with the pad face, press firmly, then twist a quarter-turn until it locks; forcing it straight on strips the threads.

When should the medium-density rubber pad be replaced if run at 25000 RPM?

Replace the pad when the rubber face shows cracking, glazing, or the TR receptacle no longer holds discs securely.
