3MTM HookitTM Clean Sanding Discs – Multihole
Premium, high performance discs that utilise a unique spiral, multihole, dust extraction technology to obtain 2–3 times more disc life. The discs attach to a dust-free sander with a hook and loop system. The spiral hole pattern means that disc alignment with the back up pad is not critical. Grades P180 and courser incorporate 3M CubitronTM ceramic abrasive mineral. The improved dust extraction decreases loading, increases cut and therefore, increases life.
