Close Coated Abrasive Disc, Medium Density Ribbed Deburring Brush, 7

3M™ disc pad face plate backs a same size fiber disc (sold separately) to provide firm support and the force required for grinding applications. It is used in conjunction with a disc pad hub (sold separately), which attaches to the power tool and held into place along with the appropriate disc using either a retainer nut (sold separately). This assembly allows the 3M™ disc pad face plate to be easily changed without removing the disc pad hub, allowing the operator to use a single tool for multiple applications from heavy grinding to finishing a workpiece.
