Abstract

A drill bit (10) for drilling a well bore (26) using solid material impactors comprising a nozzle (200) and a cavity (205) for accelerating the velocity of the solid material impactors and directing flow of the solid material impactors through the nozzle. The drill bit may also comprise a junk slot (204A) for return flow of the drilling fluid and solid material impactors.
