A grinding tool includes a toothed grinding wheel, two opposing stationary grinding members, and an actuating wheel; the grinding wheel is connected to a transmission shaft turnably connected to a housing and having an engaging end projecting from the housing; the stationary grinding members are fixedly disposed in the housing, and have grinding teeth on inward surfaces facing the grinding wheel; the actuating wheel is connected to the engaging end of the shaft at a middle connecting hole so that rotation of the actuating wheel can be passed on to the grinding wheel by means of the shaft; thus, contents of the housing can be ground with the grinding wheel and the stationary grinding members by means of holding the housing still, and turning the actuating wheel to and fro repeatedly.
