Abstract

Foret comportant des bandes de guidage. Un foret selon l'invention comporte une queue tubulaire 1 profilée arrivant jusqu'à l'extrémité du foret, la partie d'extrémité portant un élément de coupe 3 et des bandes de guidage 4 et 5, lesquelles peuvent être des éléments séparés ou bien l'élément 5 pouvant être un élément séparé et l'élément 4 faire partie intégrante de l'élément de coupe 3. Convient, en particulier, pour le perçage profond demandant une circulation importante de liquide de coupe envoyé à travers le foret pour évacuer les copeaux entre la queue du foret et la surface du trou foré.
