Review on Extended Grinder Long Shaft ZHONG by Mike Goodwin

Air line fitting broke 5 minutes after use. I ended up fixing the tool, there was enough left over to put the fitting back into the back of the mill. The rear vent on the back of the instrument is cheap plastic, the air intake is a thin-walled cast aluminum that just snapped. Wasn't very happy with the tool but after spending an hour and a half fixing it the tool seems to work well for the money.
