A tool magazine of a tool handling machine which carries several similar tools comprises a unit which can be removed from the tool machine. The tools are conducted between guide rails in a lengthwise shiftable manner. The lengthwise feed of the tools in the tool magazine takes place by means of a feed comb whose comb teeth are moved transversely into engagement between the individual tools. The feed comb carries out a driven feed movement in a lengthwise direction of the magazine. The tools are moved from the tool magazine by a tool gripping device and conducted to a tool fixture of the tool machine. Conversely, the expended tools are moved into the tool magazine by a tool gripping device.

Drive mechanism for radial adjustment of a drilling tool

A tool has independently radially adjustable cutting edges. Adjusting drives are provided for each cutting edge. Each adjusting drive is laterally spaced from, and axially overlaps, an adjacent adjusting drive. Each adjusting drive comprises a servomotor which directly drives a screw. A screw nut is axially movable on the screw and is rigidly connected by means of a bridge with an adjusting piston arranged parallel thereto. The adjusting piston is axially movable and is connected by a bearing to a tubular connecting rod. Axial movement of the latter serves to radially adjust an associated cutting edge of the tool. The connecting rods of the adjusting drives are coaxially and telescopingly arranged.
