  • Driven tool assembly
    Patent number: 8128323
    Abstract: A driven tool assembly that uses the cutting tool coolant to also lubricate and cool the driven tool. The driven tool housing has at least one coolant intake port, at least one coolant discharge port, and a shank for mounting the driven tool assembly to a machine tool. An input shaft and an output shaft are rotatably mounted in the driven tool housing, and a transmission transmits power from the input shaft to the output shaft. A seal is disposed between the housing and the input shaft. Typically, at least one passageway fluidly communicates the coolant intake port with the input shaft, the output shaft, the transmission, the bearings, and the coolant outlet port.
