Abstract

Se refiere a una broca para formar un agujero en una formacion. La broca tiene un vastago y una corona de cara completa que ayuda a definir un espacio interior que recibe agua u otro liquido de perforacion. La corona de cara completa define una pluralidad de perforaciones que se extienden desde una cara de corte de la corona de cara completa hasta el espacio interior. La corona de cara completa rodea circunferencialmente por completo el espacio interior de la broca.
