ABSTRACT OF THE DISCLOSURE A drill bit for insertion into a tool receiver of a rotary percussive drilling machine has a generally cylindrical shank portion, and a working portion extending axially from one end of the shank portion. The shank portion has a peripheral longitudinal groove open at a free end of the shank portion, the groove having a substantially flat base surface recessed from the cylindrical periphery of the shank portion and two non- radial sidewalls diverging outwardly from opposite lateral edges of the base surface toward the cylindrical periphery of the shank portion. Each sidewall forms a small obtuse angle with the base surface which is smaller than an angle formed with the base surface by a diametrical plane that intersects the lateral edge of the base surface from which that sidewall extends.
