Abstract

Broca con una caña (1) de broca y un inserto de corte fijado de forma desprendible en la misma, que forma la región de la punta de la broca, y con al menos una ranura de sujeción (3) dispuesta en la caña (1) de la broca y que se proyecta en el interior del inserto de corte (2), donde el inserto de corte se apoya con una superficie de apoyo (6), que se extiende en ángulo recto con respecto al eje medio longitudinal (8) de la broca, en la superficie frontal (7) de la caña (1) de la broca y se extiende con un pivote de fijación (9), que se proyecta centrado desde la superficie de apoyo (6), dentro de una escotadura de alojamiento (10) configurada complementaria del mismo en la superficie frontal (7) de la caña (1) de la broca, caracterizada porque al menos una sección circunferencial (13) del pivote de fijación (9) presenta una primera sección longitudinal (15), que pasa a una segunda sección longitudinal (17), con una superficie helicoidal (16) que apunta fuera de la caña (1) de la broca, seeleva hacia la punta (5) de la broca en el sentido de giro (18) de la perforación y colabora con una superficie opuesta (19) en la pared interior (14) de la escotadura de alojamiento (10).
