Abstract (en)
[origin: CA2998678A1] The invention relates to a tool for roughening a borehole surface which has a coupling portion (12) for clamping the tool (10) in a drill device and has a tool head (14) for processing the borehole surface, cutting means (18) which are circumferentially arranged on the tool head (14) being provided. A borehole surface can be roughened in a reliable manner as a result of the fact that the tool head (14) has at least one laterally continuous slot (20) which extends from an end face (22) of the tool head (14) axially along a tool longitudinal axis (A), and that the tool (10) has a suction channel (11), which extends at least partially axially along the tool longitudinal axis (A), for suctioning drilling dust, the suction channel (11) extending from the end face (22) of the tool head (14) within the tool shank (16) and opening circumferentially into a connection opening (13) in the tool shank (16).
