3M 7010029933 Hook Loop Disc 5 in 320 Grit Aluminum Oxide

Product Description

The 3M 7010029933 is a 5-inch hook and loop abrasive disc designed for fine surface preparation, finish sanding, and scratch removal on wood, metal, and painted surfaces. Built on a C-weight paper backing, the disc carries a coated aluminum oxide abrasive at 320 grit, placing it in the extra fine grade range. The gold-colored disc mounts to any 5-inch hook and loop random orbital or disc sander. Vacuum holes are included to support dust extraction during operation. Finishing carpenters, painters, auto body technicians, and general tradespeople commonly use this disc for between-coat sanding and final prep work.

This disc is suited for light material removal and surface refining in both residential and light commercial settings. The flexible paper backing conforms to slightly contoured surfaces, making it useful for cabinet faces, door panels, and trim work. The 320 grit rating is appropriate for smoothing surfaces between finish coats or preparing a surface for sealer application. The hook and loop attachment system allows fast disc changes without adhesive, reducing downtime during multi-step sanding operations.

Installation Notes

Align the disc squarely with the sander pad before pressing firmly to seat the hook and loop fastening. Ensure the sander is powered off and unplugged before mounting or removing the disc. Inspect the sander pad for worn hooks that may reduce disc retention and cause slippage during use. Operate at the speed recommended by the sander manufacturer for the grit and material being worked.
