Abstract

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. Se define una ranura con forma de cuna con la corona de cara completa que se extiende longitudinalmente con una parte de la cara de corte y la superficie circunferencial exterior de la corona de cara completa. La ranura define, ademas, un vertice ubicado mas alla del centro de la cara de corte de la broca de tal modo que el eje longitudinal de la broca se extiende a traves de la superficie inferior de la ranura y dentro del area hueca interior de la ranura. Adicionalmente, se define un conducto en la broca que esta en contacto con el espacio interno y con una parte de la ranura definida.
