Abstract
1. Un tornillo de taladrado y formación de rosca automáticos fabricado a partir de un material de acero inoxidable de serie 300, inicialmente austenítico, que comprende: un cuerpo alargado que posee una rosca helicoidal formada en el mismo; una cabeza impulsadora radialmente ensanchada en un extremo y una punta taladradora subsiguientemente formada en frío en el extremo opuesto, presentado la punta taladradora una estructura martensítica al 40 por 100- 70 por 100 que proporciona un perno de fijación con una punta taladradora que posee al menos, una dureza de superficie comprendida en los límites de 50-58 Rc y es capaz, por ende, de penetrar a través del acero, a la vez que retiene las deseables características de resistencia a la corrosión del acero inoxidable austenítico de serie 300. 2. El tornillo de taladrado y formación de rosca automáticos, según la reivindicación 1, en el cual las zonas de cabeza y cuerpo poseen una estructura martensítica de 0-40 por 100. 3. El tornillo de taladro yformación de rosca automáticos, según la reivindicación 1, en el cual el terminal de acero inoxidable austenítico generalmente comprende 7,75 por 100 a 8,25 por 100 Ni. 0,06 por 100 a 0,10 por 100 C y 17 por 100 a 18,5 por 100 Cr. 4. El tornillo de taladrado y formación de rosca automáticos, según la reivindicación 1, en el cual la punta perforadora incluye un par de bordes cortantes terminales que se extienden radialmente hacia fuera y hacia arriba y que intersecan un borde cortante lateral, una zona de canal o ranura cóncava que se extiende hacia arriba desde los bordes cortantes terminales, siendo la dimensión transversal de la punta taladradora generalmente en el plano de los bordes cortantes al menos dos veces la dimensión transversal de la punta generalmente normal respecto al plano de los bordes cortantes, siendo el área de corte transversal de la punta taladradora generalmente no mayor de un 50 por 100 del área de corte transversal del cuerpo. 5. El tornillo de taladrado y formación de rosca automáticos, según la reivindicación 1, en el cual la punta taladradora posee, al menos, 50 por 100 de estructura martensítica.
