The 3M 18730 is a 2-inch, 50-grit bristle brush disc designed for surface preparation, blending, and finishing on a variety of materials. Its abrasive-tipped bristles conform to irregular surfaces, delivering consistent scratch patterns without loading or gouging the workpiece.
Ideal for use in metalworking, fabrication, and maintenance applications, this bristle disc attaches easily to compatible angle grinders and die grinders. It is well suited for removing rust, scale, paint, and other surface contaminants while leaving the base material intact.
