3M™ Centre Pin Back-Up Pad

3M Centre-pin back up pads are used with Scotch-Brite surface conditioning discs. Used to prepare and/or finish metal surfaces in fewer steps and in less time than conventional abrasives, such as grinding discs and wire wheels. The centre-pin attachment system contributes to a reduction in tool vibration by centring, securing and maintaining the disc in the correct position on the back-up pad.
