Our 3M Disc Pad Hub enables operators to select face plates with four different levels of flexibility (soft, medium, hard and extra-hard). The disc pad hub holds a face plate firmly in position, and a center hole fiber disc is secured to the tool spindle with the retainer nut.
Disc pad hub and retainer nut has a M14-2 INT thread for use on grinders with M14-2 threaded spindle and can be used on all 3M Fiber Disc face plates. Use with 4-1/2 inch through 9 inch Fiber Discs with 7/8″/22mm center hole.
