Abstract
The invention relates to a grinding tool (1) comprising an elongated tool body (2) having a first end (20) comprising a grinding head (3) provided with an abrasive coating (4), and a second end (21), an axial channel (5) extending through the tool body (2) from the second end (21) over a given length of said body, and at least one coolant channel arranged with the axial channel (5) to allow the ejection by the grinding head (3) of a fluid introduced into the axial channel (5) at the level of the second end (21), the grinding head (3) having a terminal external surface (30) delimited by a peripheral external surface (31), said terminal external surface (30) being provided with at least one groove (6a to 6f) extending radially from the axial channel (5) to the peripheral external surface (31), said groove being closed along its length by the coating abrasive (4) to form said at least one watering channel.The invention also relates to a method for making a galvanized grinding tool.
