Abstract
This paper reviews a study of the slip of an oblique-tooth array of a cone drill bit during drilling of normal rock. The kinematics of the cutter of the drill bit, operating as the array slips along the face, is analyzed. Basic factors affecting the magnitude and direction of the slip of the teeth along the face of the hole are determined. Disadvantages of straight-tooth cone drill bits are exposed, and the advantages offered by use of an oblique-tooth array are substantia ed. Results of the investigation enable us to conclude that use of the type of array in question is promising.
