The invention concerns a method for supplying the working parts of a boring tool, in particular a drill, with a lubricant which both cools and lubricates the drill, a dispenser (9) being connected directly or indirectly to the drill to enable lubricant to be fed to the working parts of the drill through at least one channel (10) in the drill. The invention also concerns a boring tool, in particular a drill, with a shaft (1) and a cutter (2) and at least one internal lubricant channel (10), at least one reservoir being fitted as a dispenser (9) for the lubricant, the reservoir being directly or indirectly connected to the drill by mechanical means and to the at least one lubricant channel (10) to permit the passage of lubricant. In addition, the invention concerns a tool-holder designed to hold the drill. It has an internal dispenser (9a) for the lubricant, the dispenser being connected, when the drill is fixed in place, to the at least one lubricant channel (10) in the drill to permit the passage of lubricant.
