Abstract
EL TALADRADOR QUE SE COMPONE DE VASTAGO (1) Y CABEZA (2) PORTABARRENAS, ESTA PROVISTO EN SU PARTE FRONTAL (2A) Y EN EL SENTIDO DEL AVANCE DE UNA PLACA (5) Y PASADORES DE CORTE (6, 7). LOS PASADORES SIRVEN PARA DISMINUIR EL DESGASTE DE LA PLACA Y MEJORAR EL APOYO DEL TALADRO, PUDIENDO ESTAR DISPUESTOS EN PARTE INCLINADOS Y EN PARTE PARALELOS RESPECTO AL EJE DEL TALADRO. SUS EXTREMOS FRONTALES LIBRES ESTAN SITUADOS EN LA SUPERFICIE DE ROTACION FORMADA POR LAS CUCHILLAS DE LA PLACA (5).
