ABSTRACT:
The invention concerns an anti-balling drill bit. The drill bit includes an approximately cylindrical steel body provided at one end with axial arms on which are mounted toothed conical wheels. The bottom of the tool body has a dome shaped profile such as a parabolic profile, whose flanks are joined at an apex located approximately along the axis (x--x) of the tool. The flanks ascend toward the cylindrical wall of the body through gaps between the arms with unbroken surfaces and without edges, each arm bearing at its end at least one extension nozzle for emitting a liquid jet, and nozzles also being mounted in said flanks.
