Abstract

L'invention concerne les vis perceuses et autotaraudeuses. Elle se rapporte à une vis perceuse qui a une extrémité pilote 16 dont deux goujures 24 délimitent deux bords de coupe 26. Selon l'invention, une gorge 38 est formée le long du bord de coupe 26 afin qu'elle permette la découpe progressive d'un long copeau, si bien que la pénétration de la vis est facilitée au début du perçage. Application aux industries de l'automobile et de la construction mécanique. (CF DESSIN DANS BOPI)The invention relates to drilling and self-tapping screws. It relates to a drill screw which has a pilot end 16 of which two flutes 24 define two cutting edges 26. According to the invention, a groove 38 is formed along the cutting edge 26 so that it allows the progressive cutting of d. 'a long chip, so that the penetration of the screw is easier at the start of the drilling. Application to the automotive and mechanical construction industries. (CF DRAWING IN BOPI)
