Abstract

A tool holder device for rotary tools, especially a grooving head for tunnel boring machines, which is made so that it can rotate and can tilt in the direction of the axis of rotation with a constant feed rate and at the periphery of which are fixed chisels protruding essentially in the radial direction, characterized in that the chisels are arranged in several groups located one after the other in the direction of the axis of rotation, the chisels of each group being distributed on the periphery of the tool holder and the ends of the chisels of the different groups located on circles whose diameter increases from group to group towards the holder of the tool holder, and because the fronts of the chisels are approximately perpendicular to the direction of the resultant of the speed of the rotating ends of the chisels and of the advance speed of the tool holder.
