Pad saver for 225mm backing pads. Mirka's pad savers are designed to protect the backing pad from wear and tear, when sanding aggressively and continuously with net products. These cost effective pad savers, placed between the backing pad and the sanding disc, should be changed regulary. The pad savers prolong the life of the backing pad. The 25H pad saver (MIW9535011) is suitable for the Mirka® LEROS machine.
