These 9/16" disks are designed to fit on 3/32" miniature screw mandrels for use in your handheld flex shaft or foredom machine and are available in six different grits. NOTE: Always place disks on the mandrel so that the bristles curve opposite (or away) from the direction of rotation -- bristles should not be bent backward during use. These unique disks from 3M are a new type of abrasive that is superior to sandpaper, flap wheels, or other types of sanders, brushes, or abrasive wheels. Coarser grits can be used to carve, grind and texture while finer grits will smooth, burnish and polish. The 3M Cubitron and aluminum oxide grains embedded throughout the plastic bristles make them very long lasting. Individual disks are stacked to make a brush. Be sure to closely follow the directions in the package so that the disks are stacked and mounted properly.WARNING: This product can expose you to chemicals including titanium dioxide, which is known to the State of California to cause cancer (www.P65warnings.ca.gov).
