Abstract
It is suggested here that a tool for the machining of workpiece surfaces, with at least one adjustable, geometrically defined cutting edge (7) with an adjusting device (29) for the adjusting of the distance of the cutting edge (7) to the central axis (33) of tool (1), whereby the adjusting device (29) has a drive shaft (11) that acts on an adjusting gate valve (31) via a gearbox (25), which determines the distance of cutting edge (7) from the central axis (3) of tool (1), whereby it is proposed that adjusting gate valve (31) be designed as a piston valve arranged eccentrically to the central axis (33) of tool (1). Tool (1) is characterized in that transmission (25) has a high reduction and directly acts on adjusting gate valve (31).

1-6. (canceled)
A tool for machining of workpiece surfaces:
- at least one adjustable, geometrically defined cutting edge;
- an adjusting device for adjusting the distance of the cutting edge to the central axis of tool;
- whereby the adjusting device has a drive which acts via a gearbox on an adjusting gate valve, which determines the distance of the cutting edge from the central axis of the tool;
- whereby the adjusting gate valve is designed as a piston valve arranged eccentrically to the central axis of tool;
- wherein the gearbox has a gear reduction and acts directly on the adjusting gate valve and the drive of the gearbox is connected directly to the adjusting gate valve.
