I might make a foray to Sears, with the sander disk sans the sander, in order to see if this is true. I wonder if anyone has tried to fit one to their Rotozip as there are no sander disks to be found in the US. Most sander disks I have seen on the Internet are from companines in England.
I just love my father's Rotozip and its sanding, even its polishing, disk would wipe steel clean down to bare bleeping metal without grunting or sweating. It is merciless!. I just don't like the drill-mounted sanding disks as they do NOT have the 20k RPM that the Rotozip affords me.
Your help would be greatly appreciated. Ken
