Abstract

UNA BROCA CON CUCHILLAS CONCAVA QUE TIENE UN CUERPO DE LA BROCA CON UNA CONCAVIDAD EN EL EXTREMO DELANTERO CON RESPECTO AL EJE DEL MISMO. UNA PLURALIDAD DE ELEMENTOS INSERTADOS CON CUCHILLAS ESTAN SOLDADOS AL CUERPO DE LA BROCA EN LA PERIFERIA DEL EXTREMO ABIERTO DE LA CONCAVIDAD. LOS ELEMENTOS INSERTADOS CON CUCHILLAS ESTAN SEPARADOS DE TAL FORMA QUE HAY UN HUECO ENTRE LOS ELEMENTOS INSERTADOS CON CUCHILLAS ADYACENTES QUE TIENE UN TAMAÑO SUFICIENTE PARA EVITAR LA FORMACION DE UNA UNION DE SOLDADURA CONTINUA ENTRE LOS ELEMENTOS INSERTADOS ADYACENTES.A CONCAVE BLADE DRILL BIT HAS A DRILL BODY WITH A CONCAVITY AT THE FRONT END WITH RESPECT TO THE SHAFT OF THE SAME. A PLURALITY OF ELEMENTS INSERTED WITH BLADES ARE WELDED TO THE BODY OF THE DRILL IN THE PERIPHERY OF THE OPEN END OF THE CONCAVITY. THE ELEMENTS INSERTED WITH BLADES ARE SEPARATED SO THAT THERE IS A GAP BETWEEN THE ELEMENTS INSERTED WITH ADJACING BLADES THAT HAS A SIZE ENOUGH TO PREVENT THE FORMATION OF A CONTINUOUS WELDING JOINT BETWEEN THE ADJACENT INSERTED ELEMENTS.
