Abstract

Broca de perforación para martillo neumático de fondo de agujero, constituida por una cabeza que lleva útiles de perforación propiamente dichos y prolongada por un apéndice de sección menor, en el cual están tallados dientes disimétricos, viniendo a aplicarse el apéndice en el extremo del martillo, acanalado interiormente, teniendo además canales previstos para el escape del aire comprimido del martillo, caracterizada por el hecho de que, para cada diente del apéndice de la broca, la altura del flanco de desgaste, que está en contacto con el martillo durante la perforación, es superior a la del otro flanco, encontrándose formados así los canales de escape del aire comprimido entre los dientes disimétricos del apéndice de la broca y las acanaladuras del martillo.
