Abstract

Tornillo de taladrar para sujetar una parte constructiva sobre urna parte portante, especialmente una más dura, con una cabeza y un vástago que sigue a la cabeza y tiene una rosca de máquina autoterrajante, que en una sección de taladrado, a la que sigue una punta estrechada, está aplanada con una profundidad de rosca que disminuye y un diámetro exterior que disminuye también, siendo la longitud axial de la sección de taladrado aproximadamente igual al espesor de la parte constructiva que se ha de fijar y estando dimensionadas la posición y longitud axiales de una sección principal de la rosca que se encuentra más cerca de la cabeza, total de la rosca y todo el diámetro exterior, de tal manera que, en el estado totalmente penetrado del tornillo de taladrar la parte portante está atornillada con la sección principal de la rosca, estando previstas además en la sección de taladrado y en la junta dos ranuras de virutas diametralmente opuestas con sección transversal aproximadamente rectangulary un filo transversal que discurre en el extremo libre de la punta entre las ranuras de virutas, formando además las superficies de ranura de virutas que se encuentran detrás en la dirección de penetración a rosca del. tornillo, juntamente con las partes de la sección de taladrado y de la punta que han quedado entre las ranuras de virutas, bordes cortantes, y estando modificada además preferentemente la forma básica cónica de la punta por aplanamiento que parten del filo transversal, caracterizado porque en cada una de las ranuras (14) de virutas el fondo está dotado de un relleno parcial (34) cuya superficie exterior representa una superficie transversal que discurre entre las paredes laterales 36, 38 de la ranura y forma con éstas dos bordes internos (40, 42) y porque el (40, 42) que se encuentran detrás en la dirección de penetración a rosca (44) del tornillo.
