Abstract

La présente invention se rapporte à un taraud composite à guidage présentant différents diamètres. Le taraud composite comprend une lame (1) de vis et une tige (2) de vis. La lame (1) de vis est reliée à la tige (2) de vis, ou la lame (1) de vis et la tige (2) de vis forment un seul bloc. La lame (1) de vis fait corps avec plusieurs bandes (3) de lame de vis. Chaque bande (3) de lame de vis est pourvue d'une surface bord taraudeur (6) sur la surface avant. L'angle entre la surface bord taraudeur (6) sur une partie chanfreinée (4) de chaque bande (3) de lame de vis et une tangente d'un cercle concentrique est supérieur à l'angle entre une surface bord taraudeur arrière (6) et la tangente du cercle concentrique. Le diamètre d'un bas (10) de lame de vis au niveau de la partie chanfreinée (4) est inférieur au diamètre d'un fond (10) de lame de vis arrière. Une plaquette de rayonnement (8'') est disposée sur la surface bord taraudeur (6) de chaque bande (3) de lame de vis. En plus de la fonction rayonnement de chaleur, la surface bord taraudeur (6) ayant la plaquette de rayonnement (8'') améliore également l'efficacité de traitement, augmente la stabilité du taraudage et prolonge la durée de vie du taraud.
