Abstract

Unidad taladradora perfeccionada para la realización de taladros de perforación; con destalonamientos compuesta por el vástago de la broca y por la cuchilla de taladrar que va unida con el primero y que posee, además de un filo cortante frontal, unos filos cortantes laterales que sobresalen radialmente del vástago de la broca; unidad taladradora esta que va provista de un casquillo de tope que es fijable al vástago de la broca y que a efectos de constituir un soporte oscilante, se apoya en la hondonada de una placa de tope que está colocada sobre el vástago de la broca; caracterizada porque la parte del vástago de la broca, que entra en el portabrocas, tiene un diámetro incrementado para la formación de un tope, en el cual se coloca a tope el casquillo de tope con el lado suyo situado alejado del taladro de perforación.
