∮100mm Sponge Backer Pad Holder Pad Connecter

Backer pads are used as a support for soft or flexible polishing mops and abrasive discs used in power tools. They provide a secure and pliable mounting that allows the disc or pad to maintain good surface contact with flat and corrugated surfaces. The pad also ensures maximum attachment surface area when polishing or sanding. The support discs always keep the discs flat when grinding, preventing the disc edges from scuffing the piecework.
