3M 7010328800 Floor Surfacing Disc 16 Grit 7 Inches

Product Description

The 3M 7010328800 is a 16-grit floor surfacing disc designed for aggressive material removal on hardwood and commercial flooring surfaces. Built on a tough, flexible paper or combination backing, it uses a sharp, fast-cutting synthetic mineral abrasive that maintains cut rate through extended use. At 7 inches in diameter with a 5/16-inch arbor hole, the disc is precut and ready to mount. Flooring contractors and surface preparation professionals install this disc as part of routine floor sanding operations. It delivers consistent stock removal and a controlled finish profile without excessive loading on the abrasive face.

This disc is suited for residential and light commercial floor sanding applications where an aggressive cut is needed, such as initial sanding passes on raw hardwood, removal of old finish coatings, or leveling uneven plank surfaces. The 16-grit rating makes it a first-pass abrasive, typically followed by progressively finer grits to achieve a finish-ready surface. Flooring mechanics using drum or disc floor sanders will find this disc compatible with standard 7-inch disc machines.

Installation Notes

Installation is performed by licensed flooring contractors or experienced tradespeople familiar with floor sanding equipment.
