The invention relates to a tool (1) for producing a friction-welded connection between a wire and a substrate having a tool shaft (2, 3) extending in the direction of a longitudinal center axis of the tool, having a tool receptacle section (2) for fastening the tool to a tool receptacle of a friction-welding machine and having a tool tip (3) connecting to the tool shaft, wherein a face (5) of the tool (1) is allocated to the tool tip (3) and wherein, in order to receive the wire during friction-welding, there is a channel-shaped groove (7) extending in a transverse direction of the tool in the region of the face (5) which is delimited by a shell surface, which can contact the wire at least in sections during friction welding, wherein there is at least one pocket-shaped recess (11) on the shell surface such that a cross-section of the groove (7) is designed to flare in the region of the recesses (11) and there is a wall of the recess (11) set back opposite the shell surface.
