Abstract:
A tool for roughening a borehole surface. The tool includes a coupling portion for clamping the tool; a tool head for machining the borehole surface; and an extraction duct. The coupling portion is disposed at a first end of a tool shank and the tool head at an opposite, second end of the tool shank. The tool head has a cutter disposed circumferentially on the tool head. The tool head has a slit, which passes through from one side to the other and which, starting from an end face of the tool head, extends axially along a longitudinal axis of the tool. The extraction duct extends at least partly axially along the longitudinal axis of the tool for extraction of drilling dust. The extraction duct, starting from the end face of the tool head, extends inside the tool shank and discharges circumferentially into a connecting opening in the tool shank.

Claim (Index 5):
The tool according to  claim 1 , wherein\n the tool head comprises at least two mutually intersecting slits that extend, starting from an end face of the tool head, axially along the longitudinal axis of the tool.
