3M 7100112077 Sanding Disc 3 Inch P800 Grit

Product Description

The 3M 7100112077 is a 3-inch hook-and-loop coated abrasive sanding disc engineered for finishing applications where dust control and disc longevity are priorities. Built on a light A-weight paper backing, this disc uses aluminum oxide mineral that cuts fast and holds up across a range of surfaces. The proprietary multi-hole pattern improves dust extraction beyond what standard 5- or 6-hole disc designs provide, keeping the work surface cleaner and extending disc life. An open-coat construction paired with a load-resistant coating resists clogging, helping maintain consistent cut rate throughout the life of the disc. Licensed finishing tradespeople and detail-oriented fabricators are the primary installers of this consumable.

This disc is suited for finish sanding in woodworking, automotive refinishing, and light metalwork where a fine P800 grit is appropriate. The hook-and-loop attachment system allows fast disc changes without tools and supports disc reuse when the abrasive surface remains serviceable. The multi-hole dust extraction pattern is designed to pair with compatible random orbital and line sanders that use vacuum or dust-collection ports, reducing airborne particulate at the point of cut.

Key Features

• P800 grit aluminum oxide mineral for fine finishing passes
• Proprietary multi-hole pattern extracts dust more effectively than 5- or 6-hole designs
• Open-coat construction resists loading and clogging
• Load-resistant coating extends usable disc life
• Light A-weight paper backing suited to finishing work
• Hook-and-loop attachment allows fast, tool-free disc changes and disc reuse

Compatibility

Designed for use with hook-and-loop random orbital sanders equipped with multi-hole dust extraction pads accepting 3-inch abrasive discs.

Installation Notes

Attachment and removal requires no tools — align the disc face to the sanding pad and press firmly to seat the hook-and-loop interface. Ensure the sander is powered off and disconnected before changing discs. Connect the sander to a dust collector or vacuum system to take full advantage of the multi-hole extraction pattern. Inspect the disc before each use and discard if the abrasive mineral or backing shows damage.
