3M 7100078180 6 Inch P400 Sanding Disc Clean Sanding

Product Description

The 3M 7100078180 is a coated abrasive sanding disc designed for finish sanding applications in woodworking, automotive bodywork, and light metal prep. Built on a C-weight paper backing, this disc features aluminum oxide abrasive grains and a proprietary multi-hole dust extraction pattern that removes sanding debris more effectively than standard 5- or 6-hole configurations. The open-coat, load-resistant construction resists clogging, extending disc life and maintaining consistent cut rate throughout use. The hook and loop attachment system allows for fast disc changes and disc reuse without tools.

This disc is suited for orbital and random-orbital sanders used in finish sanding passes on bare wood, paint, primer, and light gauge metal surfaces. The P400 grit rating places it in the fine finishing range, making it appropriate for final prep before topcoat application or between-coat scuffing. It is commonly used by finish carpenters, cabinet makers, auto body technicians, and painters working in both shop and field environments.

Key Features

• Proprietary multi-hole pattern provides superior dust evacuation compared to 5- or 6-hole disc designs, extending disc life
• Open-coat aluminum oxide grain resists loading and cuts faster and longer than traditional garnet abrasives
• Load-resistant coating prevents clogging to sustain cut rate and surface finish quality
• C-weight paper backing provides firm support for aggressive sanding passes
• Hook and loop attachment allows tool-free disc changes and disc reuse
• No hole alignment required during installation

Compatibility

Designed for use with 6 inch hook and loop random-orbital and orbital sanders accepting multi-hole disc patterns.

Installation Notes

Power down the sander and disconnect it from its power source before changing discs. Align the disc flat against the sanding pad before engaging the tool to ensure full surface contact. Inspect the hook and loop pad for wear periodically, as a degraded pad will reduce disc retention and sanding performance. Dispose of worn discs per local waste disposal guidelines.
