Method and device for preventing a drilling chip from winding around drill bit and for removing a drilling chip deposited in flutes of drill bit

摘要

A method and a device for preventing a drilling chip from winding around a drill bit and for removing the drilling chip deposited in flutes of the drill bit comprising a drill bit acting as a driving member and a driven gear having at least one tooth engageable with flutes of the drill bit. As the drill bit is turned to drill a hole, the driven gear is actuated to turn such that the tooth of the driven gear engages the flute of the drill bit so as to scrape off any drilling chip deposited in the flute of the drill bit and to prevent the drilling chip from winding around the drill bit in action. The driven gear is rotatably and movably fastened to a support rod which is in turn fastened to a drill press.
