Abstract
The invention therefore provides a tool holder for tools supplied with coolant or lubricant, especially rotating tools such as boring or milling tools, with an internal duct system for passing coolant or lubricant to the shank of the tool. To enable particularly flexible use of machine tools, the tool holder is equipped according to the invention with a lubricant reservoir which is integrated into the tool holder and which is preferably fillable and pressurizable, which during operation of the tool can be decoupled from a coolant or lubricant source and supplies the tool controllably with coolant and lubricant via a metering unit.
