Abstract:
A grinder assembly includes a spindle selectively rotatable about a central axis. The grinder assembly also includes a grinding wheel attachable to and detachable from the spindle. The grinding wheel is rotatable about the central axis when attached to the spindle. The grinder assembly further includes an adaptor cooperating with the spindle and the grinding wheel to provide a quick attachment and detachment of the grinding wheel with the spindle. The adaptor includes a plurality of first teeth extending outwardly relative to the spindle and a plurality of second teeth extending outwardly relative to the grinding wheel. The first and second teeth cooperate with each other to selectively attach the grinding wheel to the spindle and prevent independent rotation of the grinding wheel relative to the spindle.
