3M 7010384122 Floor Surfacing Disc 7in X 7/8in 36 Grit

Product Description

The 3M 7010384122 is a Regalite floor edger surfacing disc designed for use with floor edging machines on bare wood and non-gummy finish removal applications. Built around 3M's purple Regalite mineral abrasive, this 7 inch x 7/8 inch disc runs cooler than conventional abrasives, which reduces loading and extends disc life. The coarse 36-grit cut rating makes it well suited for aggressive stock removal on hardwood floors. A tough paper backing supports the abrasive layer under the lateral stress typical of edger operation. Flooring contractors and finish carpenters are the primary installers of this disc type.

This disc is intended for floor edging machines in residential and light commercial flooring applications. It performs on bare wood subfloors and hardwood finish floors where aggressive material removal is needed before finish coats are applied. The 7/8 inch arbor hole fits standard floor edger spindles. At 36 grit, this disc is a first-pass or heavy-removal option, typically followed by finer grit passes before sealing or finishing. It is sold individually (each).

Installation Notes

Disc installation and floor edger operation is typically performed by flooring contractors or finish carpenters. Before changing discs, disconnect or power down the floor edger completely. Inspect the backing pad for damage before mounting a new disc, as a worn pad can cause uneven abrasive contact or premature disc failure. Always wear appropriate respiratory protection and eye protection when operating floor edging equipment, and follow applicable occupational safety guidelines for dust management in the work area.
