3M 05575 PSA Disc Backup Pad 5 Inch Pack 10
This 3M adhesive-backed disc backup pad measures five inches in diameter and features a medium-density foam construction. It uses a threaded 5/16-24 shaft for secure attachment to compatible hand sanders. The yellow tapered pad supports a maximum operating speed of 10000 RPM and is sold in a convenient pack of ten units.
Replaces Worn Pads For Consistent Sanding Finish
Swap out a damaged or glazed backup pad when the adhesive surface no longer holds discs flat or when vibration increases during operation. A fresh pad restores even pressure across the abrasive, preventing swirl marks and extending disc life. The upgrade is worth it whenever the current pad shows uneven wear, loss of grip, or foam breakdown that affects surface quality.
Suits Shops Running High Volume Disc Changes
This pack suits professional shops and frequent users who need multiple pads ready for quick changeovers on non-vacuum sanding systems. The threaded shaft fits tools accepting a 5/16-24 connection, while the medium density handles general-purpose sanding tasks. Buyers needing vacuum-hole pads for dust extraction, alternative densities for specialised finishes, or different shaft sizes should look at other configurations.

Questions about this item
Will the 5/16 in.-24 threaded shaft fit my sander's spindle?
The pad uses a 5/16 in.-24 threaded shaft; match that thread to your tool's spindle before mounting.
How do I attach the adhesive-backed discs without them shifting?
Clean the pad face, peel the disc liner, centre the disc on the 5 in. foam surface, then press firmly from the middle outward.
When should I replace the yellow foam backup pad?
Replace the pad when the foam loses medium density, the tapered edge wears unevenly, or the adhesive no longer holds discs securely.
