Abstract
PARA LA FABRICACION DE TALADROS CILINDRICOS EN HORMIGON O ANALOGOS SE UTILIZAN BROCAS CON VASTAGO RECTO. DURANTE LA PENETRACION EN EL MATERIAL SE PRODUCE CON FRECUENCIA UN AGARROTAMIENTO O UNA INCLINACION DE LAS BROCAS CONVENCIONALES. SE PROPONE UNA BROCA PARA LA FABRICACION DE TALADROS CILINDRICOS EN CUYO VASTAGO (5) SE PREVEN DOS O MAS ENSANCHAMIENTOS (6, 7) ABOMBADOS DEL VASTAGO DISPUESTOS UNO DETRAS DE OTRO, CUYO DIAMETRO MAXIMO EQUIVALE APROXIMADAMENTE AL DIAMETRO DE LA CABEZA DE TALADRADO. ENTRE LAS RANURAS PARA LA VIRUTA SE FORMAN TABIQUES (12) ANCHOS, QUE OFRECEN UNA SUPERFICIE DE APOYO BUENA DE LOS ENSANCHAMIENTOS DEL VASTAGO.
