The hard 150 mm sanding backing pad uses an M8 fitting and a multi-hole layout for the stated ER, BR and RH tool families. Its role is abrasive support and dust-path alignment, not polishing.
The backing pad supports the abrasive and, where provided, routes sanding dust through its openings. The fitting and hole layout matter as well as the working diameter.
