Optimized for use with the M12 FUEL™ 6” Random Orbital Sander, our MILWAUKEE® 6” Pressure Sensitive Adhesive Sander Backing Pad – Firm is a replacement pad that features a Pressure Sensitive Adhesive (PSA) design to adhere the sander paper to the pad. The firm pad is designed specifically with the body technician in mind, allowing the user to shape body filler and remove paint to bare metal. When paired with the M12 FUEL™ 6” Random Orbital Sander, the pad and tool combination is optimized for vibration for long durations of usage along with the preferred removal rate of body filler.
