3M 7010401375 Floor Surfacing Disc 7in 150 Grit

Product Description

The 3M 7010401375 is a precut floor surfacing disc designed for sanding and finishing hardwood and wood-composite floors. The disc uses a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible paper or combination backing. At 7 inches in diameter with a 0.875-inch center hole and a 150-grit rating, this disc is suited for fine finishing passes that smooth and prepare floor surfaces for staining or sealing. Flooring contractors and wood floor technicians rely on this disc for consistent cut rate and finish quality across large surface areas.

This disc is intended for use with standard floor sanding machines that accept 7-inch disc pads with a 0.875-inch arbor hole. It is well suited to residential and light commercial flooring applications, particularly during finish-sanding stages where controlling scratch pattern and surface uniformity is critical. The 150-grit designation makes it appropriate for final prep work before applying stain, sealer, or topcoat finishes on wood floors.

Installation Notes

Flooring contractors should ensure the sanding machine pad is clean and free of debris before mounting the disc to prevent uneven contact.
