Abstract: A tool holder for carrying a cutting insert wherein the cutting insert is useful for the removal of material during a material removal operation. The tool holder includes a tool holder body. The tool holder body includes a pocket adapted to carry the cutting insert, a coolant inlet in communication with a pressurized source of coolant, a coolant chamber having a central region, an upstream coolant passage having a central longitudinal upstream coolant passage axis, and a downstream coolant passage having a central longitudinal downstream coolant passage axis. The upstream coolant passage opens into the coolant chamber. The upstream coolant passage has an orientation relative to the coolant chamber so that the central longitudinal upstream coolant passage axis is offset from the central region of the coolant chamber whereby coolant flows into the coolant chamber in a tangential fashion.
