Abstract
Tornillo auto-taladrador que incluye un vástago de forma alargada, una cabeza ensanchada en una extremidad con un dispositivo que puede cooperar con una herramienta para hacer girar el tornillo, incluyendo el vástago de forma alargada una porción roscada situada entre la cabeza ensanchada y la porción de extremidad de penetración del vástago, una punta de perforación formada en dicha porción de extremidad de penetración que incluye un par de ranuras dispuestas en posiciones opuestas y orientadas de manera generalmente longitudinal que se extienden hacia arriba y que cortan un par de superficies achaflanadas planas formadas en cada lado de un borde saliente terminal que corta de manera sustancialmente perpendicular el eje longitudinal del vástago, incluyendo cada una de dichas ranuras unas primera y segunda superficies que se cortan y que están dispuestas de manera sustancialmente longitudinal, cortando dichas superficies ambas superficies achaflanadas y extendiéndose la parte lateral principal de dicha primera superficie con un ángulo no superior a 45º respecto al borde saliente terminal, formando así unos filos de corte dispuestos lateralmente, incluyendo dichas primeras superficies un par de superficies planas que se cortan dispuestas linealmente tanto en la dirección longitudinal como en la dirección lateral, estando ambas superficies planas que se cortan inclinadas respecto al eje longitudinal del tornillo y estando la más baja de dichas superficies inclinada en un grado inferior a la más alta de dichas superficies, estando dichas segundas superficies constituidas por dos superficies que se cortan, que presentan una forma curva en la dirección longitudinal, formando la intersección de las superficies curvas un nervio vertical separado axialmente de los filos de corte y que se extiende de manera general lateralmente respecto al eje longitudinal, estando dichas primera y segundas superficies separadas por un ángulo de 92º a 97º, la una respecto a la otra para asegurar un destalonado adecuado detrás de los filos de corte dispuestos lateralmente.
