Abstract

Outil de coupe rotatif, du type à lame, destiné à la réalisation de trous coniques dans des pièces métalliques Il comporte une lame allongée 12, à peu près plate, effilée dans la direction de sa largeur et dans la direction de son épaisseur, de manière que des arêtes de coupe, formées le long des bords de cette lame, précèdent des arêtes de coupe proches de la pointe de la lame et atténuent ainsi les déviations de cette pointe. Toutes les arêtes de coupe de la lame ont un angle sensiblement négatif de dégagement. Domaine d'application : montage de dispositifs de fixation pour véhicules aériens et spatiaux.
