3M 7010320722 Floor Surfacing Disc 60 Grit

Product Description

The 3M 7010320722 is a precut floor surfacing disc designed for drum and belt sanding machines used in hardwood floor refinishing and surface prep. The disc features a sharp, fast-cutting synthetic mineral abrasive bonded to a tough, flexible paper or combination backing. At 6.875 inches in diameter with a 0.875-inch arbor hole and a 60-grit abrasive grade, it is suited for aggressive material removal and initial passes on bare or previously finished wood floors. Flooring contractors and restoration crews install these discs to reduce sanding time while delivering a consistent, even finish across large surface areas.

These discs are used in professional floor refinishing applications on residential and light commercial wood floors. The 60-grit rating makes them appropriate for the early stages of refinishing — removing old finish, leveling minor surface irregularities, and preparing raw wood for finer finishing passes. They are sold individually and are sized to fit standard drum sanding equipment used in the flooring trade.

Key Features

• Precut disc format for fast, tool-free installation on compatible drum sanders
• 60-grit synthetic mineral abrasive for aggressive stock removal on wood floors
• Tough, flexible paper or combination backing resists tearing during extended use
• 6.875 x 0.875 inch dimensions sized for standard floor-surfacing drum equipment
• Fast-cutting construction reduces passes required to clear old finish or level surfaces

Compatibility

Designed as an OEM-style replacement disc for standard drum floor sanding machines that accept 6.875-inch precut surfacing discs.

Installation Notes

Installation is performed by flooring contractors and experienced trade professionals. Before changing discs, power down the sander completely and allow all moving parts to stop. Follow the machine manufacturer's loading procedure to ensure the disc seats flat and secure before operation. Always wear appropriate respiratory protection and eye protection during floor sanding operations, and follow applicable local safety codes for dust containment.
