Abstract

Perfeccionamientos introducidos en una broca que comprende un vástago provisto de dos rebajos de retirada de virutas que se extienden axialmente y al menos dos piezas insertas de corte, estando dispuestas dichas piezas insertas radialmente y comprendiendo una pieza inserta periféricamente situada junto a uno de dichos rebajos de retirada de virutas, extendiéndose el filo de dicha pieza inserta radialmente de tal manera que forma el diámetro del agujero, y una pieza inserta situada junto al otro de dichos rebajos de retirada de virutas, pero estando situada radialmente dentro de la periferia de la broca, extendiéndose dichas piezas insertas en sentido axial básicamente en igual medida, caracterizados porque la pieza inserta más interior tiene un emplazamiento radial tal y está dispuesta alejada de la pieza inserta periférica bajo un ángulo (180+- gamma) de un valor tal que, visto radialmente, se consigue un equilibrio de fuerzas del vástago de la broca.
