3M 7010301729 Regalite Floor Surfacing Disc 40 Grit

Product Description

The 3M 7010301729 is a Regalite abrasive floor surfacing disc designed for use with floor edger machines on bare wood and non-gummy finishes. Measuring 7 inches in diameter with a 5/16-inch arbor hole, this disc runs at 40 grit for aggressive material removal during floor preparation and refinishing work. The Regalite mineral construction allows the disc to cut faster, run cooler, and outlast conventional abrasive discs, reducing downtime and disc changes on the job. 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 consumable.

This disc is suited for residential and light commercial wood floor refinishing applications where an edger machine is used to sand along baseboards and in corners that drum sanders cannot reach. It is used on bare hardwood, softwood strip flooring, and similar wood surfaces that have not been treated with a gummy or heavily built-up finish. The 40-grit rating makes it appropriate for initial cut-down passes and leveling work rather than fine finish sanding.
