ABSTRACT:
The present invention discloses an apparatus and method for directing drilling fluid to the cutting tip of a downhole drilling bit cutter by one or more flow channels formed in the upper section of the cutter's front surface, thereby maximizing the cleaning and cooling effect of the fluid flow on the actual cutting surface. Another embodiment of the present invention discloses an apparatus and method for helping to peel a rock chip from the face of a downhole drilling bit cutter while simultaneously cleaning and cooling the drill bit cutter cutting tip.
