3M™ Disc Pad Hub has an internal threaded metal insert that threads onto the shaft of a sander and grinder to hold a disc pad face plate and fiber disc in place.
Use 3M™ Disc Pad Hub to hold face plates firmly in position. Our disc pad hub supports fibre discs with a 7/8 inch centre hole which is secured with a compatible retainer nut. The hub enables operators to select face plates (sold separately) with four different densities: soft, medium, hard and extra hard. This offers the convenience of using a single power tool for multiple grinding applications.
