Orbital sander to 5/8" adapter

[bkvanbek]

I want to use threaded wire brushes and diamond cup wheels, made for 4" electric grinders, on my air sander, powermate 5" from Menards
What size is the threaded spindle? Or what is it called?

I need a bump. Hasn't anyone wanted to run a threaded grinder tool on an air sander?

You probably wont find anything most wire brush cups have a max speed of around 15 000RPM and some are less, your high speed sander runs 18 000 RPM. Im not sure the tool would have a descent amount of torque to even make it useful.
