Abstract: A grinding tool (1) including an elongated tool body (2) including a first end (20) including a grinding head (3) with an abrasive plating (4), and a second end (21), an axial channel (5) running through the tool body (2) from the second end (21), over a given length of the body, and at least one coolant feed tube arranged with the axial channel (5) to allow the grinding head (3) to eject a fluid introduced into the axial channel (5) at the second end (21), the grinding head (3) having a terminal outer surface (30) bounded by a peripheral outer surface (31), the terminal outer surface (30) having at least one groove (6a to 6f) running radially from the axial channel (5) to the peripheral outer surface (31), the groove being closed off along its length by the abrasive plating (4) to form the at least one coolant feed tube. The invention also relates to a method for making a galvanised grinding tool.
