Abstract

A drill bit for forming a hole in a formation. The drill bit has a shank and a full face crown that cooperate to define an interior space that receives water or other drilling fluid. The full face crown defines a plurality of bores that extend from a cutting face of the full face crown to the interior space. The full face crown completely circumferentially encloses the interior space of the drill bit. A wedge shaped slot is defined therein the full face crown that extends longitudinally therein a portion of the cutting face and the circumferential outer surface of the full face crown. The slot further defines an apex that is positioned beyond the center of the cutting face of the drill bit such that the longitudinal axis of the drill bit extends through the bottom surface of the slot and into an interior void area of the slot. Further, a conduit is defined in the drill bit that is in communication with the interior space and with a portion of the defined slot.
