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.
