5 in PSA Disc Backup Pad

The Ingersoll/Rand 49094-1 is a foam backup pad designed for adhesive-backed sanding discs. It attaches via a 5/16 in.-24 threaded shaft and measures 5 in diameter by 3/8 in thick. The soft-density foam conforms to contours during finishing work. Maximum operating speed is 12,000 RPM.

Suited for and not suited

This pad suits operators running orbital or rotary sanders that accept a 5/16 in.-24 threaded shaft and 5 in discs. It does not suit tools requiring a hook-and-loop face, a vacuum-hole pattern, or a different thread size. Buyers needing a firm-density pad or a quick-change mounting system should look at other options.

12,000 RPM maximum speed

The 12,000 RPM rating is the decisive limit for safe use. The sander's no-load speed must not exceed this figure. Exceeding it risks pad failure and injury. Verify the tool's documented speed before mounting this pad.

Questions about this item

Is the 5 in PSA disc backup pad the only size available for this model?

The 49094-1 is supplied as a 5 in diameter round pad with a 5/16-24 threaded shaft and 3/8 in thickness.

What does the 12,000 RPM maximum operating speed mean for daily sanding work?

The pad is rated to run safely up to 12,000 RPM on compatible sanders, so it matches high-speed orbital or rotary tools without exceeding its limit.

How does the 5/16-24 threaded shaft connect to my sander?

The 5/16-24 threaded shaft screws directly into sanders that use the same thread pattern, providing a secure mount for the adhesive-backed discs.
