For sale is a Milwaukee Bench Grinder. 3/4 HP, 8 inch wheels, 115 volts AC. It runs well. I installed a new capacitor in it and brand new, expensive double sealed bearings, all from McMaster-Carr. The bearings alone were $7.72 each, not some cheap junk. The bearings are sealed, so the grinding dust cannot get into them.
The grinder has one wheel, but it has the washers and other hardware for mounting a second wheel.
