Abstract
The present invention deals with a bore head for deep-hole boring, in which a plurality of circumferentially spaced cutting members may be radially displaced in the bore hole by a common actuating device during operation. The actuating device includes an actuating rod for each cutting member, which actuating rod is in engagement with its associated cutting member by gear means including inclined teeth. The actuating rods are secured to a central actuating bar by a common connecting member. The bore head is interchangeably secured to a boring tube, and the actuating rod may be separated from the connecting member by a coupling which is automatically engaged and disengaged during changing of the bore head.
