Unlike Proxxon's 28548 Velcro backing disc, this Relativity™ 44702 backing disc has full-face Velcro coverage, permitting the entire disc area to be used. Suitable for use with 28030 SP/E, the extra-thick and extra-soft polyurethane backing disc has no centre hole! Instead this Relativity™ 44702 backing disc has a precise aluminium centering boss and inbuilt M8 left-hand thread, perfectly matching the leftmost shaft end of 28030 SP/E.
We chose the same polyurethane hardness as 3M's Hookit™ generic discs, but the Relativity™ 44702 discs have custom-designed aluminium cores which mate with the Proxxon SP/E grinder, truly centered for smoothest rotation.
One 50mm / 2inch red polyurethane bevelled disc with 20mm centering boss, M8 left-hand thread, full-face hook Velcro.
