ABSTRACT:
A main frame supports a first shaft rotatably so that a grinding wheel mounted at the end of the shaft may be rotated. A second shaft supports at one end a drill bit holding element for supporting a drill bit which is to be sharpened. The drill bit holding element has a first arm and a second arm for receiving the end of the second shaft, one arm being used in order to sharpen one facet of the drill bit end, and the other arm being used to sharpen the other facet of the drill bit end. A locking frame integrally connected with the arms is telescopically received in a hollow frame, which plate is urged upwardly toward the top surface of the hollow frame to lock in place a drill bit between the top V-shaped surface of the locking plate and the top surface of the hollow frame. A gauge is also provided in the top surface of the hollow frame in order to initially position the drill bit end relative to the grinding wheel surface.
