3M™ Roloc™ Discs
3M™ Roloc™ Discs provide a fast, efficient method for grinding,
blending, leveling and finishing on all types of metal. They lock
securely in place with just a half twist…another half twist and
they’re off. Each disc is color coded by grade. (This does not
include 3M Roloc TSM products.)
