摘要： A relatively low cost twist drill sharpener apparatus employable with a rotary grinding wheel has a twist drill alignment fixture which positions the drill with respect to the drill holding chuck. The twist drill holding chuck has mounted thereto one or a pair of cam elements which cooperate with a sharpener fixture which is adjustable for height, pivotal motion and backward and forward motion relative to the rotary grinding wheel. The fixture has mounted thereto a second cam and is adapted to receive the twist drill chuck and control the grinding of the twist drill when the chuck is pressed toward the face of the grinding wheel and rotated clockwise. The fixture and the chuck are also adapted to receive a wheel dressing element.
