Boring shaping tool has cutting edge on one end at varying spacing from longitudinal axis

摘要

The tool (1) shapes a boring (2) in a screw (3). It has a longitudinal axis (6), along which the tool extends, a cutting edge (9) on the first end (7) of the tool and with varying spacing from the longitudinal axis. A grip device (15) grips the second end (8) to drive the tool into the boring in the cutting direction along the axis.
