3M 7100048730 Sanding Disc 5 Inch P800 Grit Aluminum Oxide

Product Description

The 3M 7100048730 is a coated abrasive hook-and-loop sanding disc engineered for fine finishing work in woodworking, automotive, and general surface preparation applications. Built on a light A-weight paper backing, this 5-inch disc uses aluminum oxide mineral to deliver fast, consistent cuts across a wide range of surfaces. The open-coat construction combined with a load-resistant coating minimizes clogging, extending disc life and maintaining cut rate through the full service life of the abrasive. The P800 grit rating makes it well suited for fine sanding passes where surface finish quality is the priority.

This disc is intended for finishing applications where controlled material removal and surface quality matter. The multi-hole pattern is designed to work with compatible hook-and-loop random orbital and orbital sanders that support dust extraction. Typical users include finish carpenters, cabinet makers, auto body technicians, and general contractors performing final-stage sanding before coating or painting. The dust extraction design keeps the work surface and disc cleaner, reducing the frequency of disc changes on the job.

Key Features

• P800 grit aluminum oxide mineral delivers fast cutting with a fine finish
• Multi-hole pattern provides improved dust extraction compared to standard 5-hole and 6-hole disc configurations
• Open-coat construction and load-resistant coating resist clogging and extend disc life
• Hook-and-loop attachment allows quick disc changes and disc reuse
• Light A-weight paper backing is appropriate for finishing passes
• 5-inch diameter fits standard hook-and-loop random orbital sanders

Compatibility

Designed for use with hook-and-loop random orbital and orbital sanders that accept 5-inch discs with a multi-hole dust extraction pattern.

Installation Notes

Attachment and removal require no tools — press the disc firmly onto the sander pad to engage the hook-and-loop fastening system. Ensure the sander is powered off and unplugged before changing discs. Inspect the pad backing for wear or debris before attaching a new disc, as a damaged pad can cause uneven contact and reduce abrasive performance. Dispose of worn discs per local regulations for coated abrasive materials.
