It works
This was hard to find, but it is just the thing for fitting a velcro foam backing pad to a drill. I have a Griott's Garage polisher, which foam backing pads fit onto with their embedded bolt/stud. In order to use a 3 inch backing pad (designed for the polisher) on a drill, you need something like this, to covert the threaded stud into a smooth shaft that will fit into a drill. It works well.
