 They can be fitted to the Hum-B Variable speed upright grinder or on any standard 7-in. angle grinder and are available in 12 grits. Four are designed to prep the floor and remove gouges and scratch marks left behind by cup wheels in the initial prep work. The remaining eight are for polishing floors to a high gloss.
