Ali Industries 4142 5-Inch 80-Grit 8-Hole Hook & Loop 15-Pack Sanding Discs

5-Inch 80-Grit Sanding Discs

These 5-inch hook-and-loop discs suit wood metal drywall fiberglass and painted surfaces. The 80-grit aluminum oxide abrasive handles intermediate material removal and surface preparation. Packaged in a 15-count box they fit random-orbit or finishing sanders with an 8-hole pattern. The quick-change backing speeds disc swaps during multi-stage jobs.

Hook & Loop Quick-Change Limits

The hook-and-loop interface requires a matching 8-hole backing pad to align dust extraction and prevent misalignment. Resin bonding resists heat and humidity yet the discs will load faster on resinous woods or soft metals without regular cleaning. Grit 80 is too coarse for final finish sanding and too fine for heavy stock removal on thick coatings.

Replaces Worn 80-Grit Discs

This pack replaces depleted 80-grit hook-and-loop discs when cutting rate drops or backing tears. The jump is worth it when the old discs no longer clear dust through the 8-hole pattern or when the abrasive glazes over on painted surfaces. Buyers who need finer finishing grits or heavier coarse grits should select a different grade.
