3M 7010384123 Floor Surfacing Disc 7 in X 7/8 in 50 Grit

Product Description

The 3M 7010384123 is a Regalite floor surfacing disc engineered for floor edger machines used on bare wood and non-gummy finishes. Measuring 7 inches in diameter with a 7/8-inch arbor hole, this 50-grit abrasive disc uses the Regalite mineral grain, which is self-sharpening by design, allowing it to cut faster, run cooler, and outlast conventional abrasive discs. The tough paper backing resists tearing under the rotational stress of floor edger use. Flooring contractors and finish carpenters rely on this disc for edge sanding work where drum sanders cannot reach.

This disc is suited for residential and light commercial flooring applications. It is used in floor edging machines to sand bare wood flooring along walls and in corners. The 50-grit rating makes it appropriate for stock removal and initial surface preparation before progressing to finer grits. It performs well on unfinished hardwood and softwood flooring where a non-loading abrasive is needed to maintain consistent cut rate across the disc life.

Key Features

• Regalite mineral grain cuts faster and runs cooler than conventional abrasive minerals
• Tough paper backing withstands rotational stress of floor edger machines

Installation Notes

Floor edger discs are installed and serviced by flooring contractors and finish carpenters. Disconnect the floor edger from its power source before changing discs. Ensure the disc seats flat against the backing pad and that the arbor fastener is secured before operation. Inspect the backing pad for damage prior to each disc change, as a worn pad can cause uneven sanding or premature disc failure.
