I found the plastic material on GP's spinner is pretty tough. It can easily break the abrasive cutting wheel if the spinner is pushed too hard against the wheel. So use caution.
One of the problems you may be having it that even if you put that drill press on its highest speed, it is still about 1/4 what a Dremel tool turns. Those abrasive wheels work better at higher RPM.
