Meshpower is a multi-functional abrasive with a high cut rate and an incredible dust extraction thanks to thousands of tiny holes created by the unique mesh matrix structure. Mesh backing enables excellent dust extraction, for a cleaner working environment and less clean up time. No-fil® technology prevents clogging for longer product life and better finish results. Self-grip backing for a quick and easy disc change. No defined hole pattern for fast, easy alignment with the back-up pad. Clipper grinding disc M920 SB Meshpower can be used wet or dry, on many materials, flat and contoured surfaces, by hand or machine.
