Abstract:
(EN) A drill bit including: a main body portion including three legs extending therefrom, the three legs arranged around a periphery of the main body portion; a conical cutter rotatably mounted on each leg, the conical cutters positioned to allow a clearance between the conical cutter and the main body portion; a protrusion extending from the main body portion into the clearance, wherein the protrusion encourages drill cuttings away from a base region of the main body portion where the legs meet the main body portion.
