A grinding tool for use with an automatic tool changing system in conjunction with a machine spindle and a source of cutting fluid. A preferred embodiment of the grinding tool includes a tool holder adapted for attaching the grinding tool to a machine spindle, and an attachment structure for placing the grinding tool in fluid communication with a source of pressurized fluid. The grinding tool further can comprise a fluid distribution passageway having a central supply tube formed within the tool holder, an annular space and guide channels formed within the body of the grinding wheel, and a plurality of non-perpendicular fluid delivery openings formed in the grinding surface so that coolant fluids at pressures of 200 psi and greater can be received within the fluid distribution passageway and delivered in a controlled manner toward the grinding surface via the delivery openings for either cleaning the grinding surface, for cooling and otherwise lubricating the workpiece and the grinding tool, or both.
