Abstract

A rapid attachment is described for the drill bit for the fast perforator in the fabrication of tubes, able to connect in easily immovable fashion said drill bit 1 to the corresponding rod 3. It is comprised of a metal body 2, secured, for example by screwing, in an appropriate lodgement of the rod 3 and, at the opposite end turned toward the tip 1, having a pocket 11 to accommodate a corresponding shank 10 of the bit 1. The connection is produced by a pair of cylindrical and parallel pegs 6, prevented from coming out of corresponding seats by a ring 4 surrounding the front portion of the attachment 2 and in turn maintained in position by the engagement of its rear edge with a pin 5 normally elastically thrust toward the outside by a compression spring. <IMAGE>
