3M 7010339982 Regalite Floor Surfacing Disc 40 Grit

Product Description

The 3M 7010339982 is a Regalite floor edger disc engineered for sanding bare wood and non-gummy floor finishes. Built around 3M Regalite abrasive mineral on a tough paper backing, this disc cuts aggressively while running cooler than conventional abrasive discs, extending working life between changes. At 6-7/8 inches in diameter with a 7/8-inch arbor hole and a 40-grit cut, it is sized specifically for floor edger machines used in hardwood floor sanding applications. Flooring contractors and finish carpenters reach for this disc when stripping old finish or leveling raw wood close to walls and edges where drum sanders cannot reach.

This disc is intended for use with standard floor edger machines on residential and light commercial hardwood flooring projects. The 40-grit rating makes it appropriate for aggressive material removal on bare wood substrates or for cutting through thick, non-gummy old finishes. It is not recommended for gummy or resinous coatings, which can load the abrasive and reduce cut rate. Flooring professionals typically use this disc as part of a multi-stage sanding sequence, starting with coarser stock removal before stepping up to finer grits for finish preparation.

Installation Notes

Floor edger discs are installed and serviced by flooring contractors. Before changing a disc, power down the edger machine and disconnect it from the power source. Ensure the disc is properly seated and secured to the backing pad before operating the machine. Always wear appropriate personal protective equipment including eye protection and a dust mask or respirator when operating floor sanding equipment.
