  • Patent number: 5597276
    Abstract: An apparatus is provided to allow a conventional tube grooving tool to be used to create a vent hole in a tube behind the tube sheet of a boiler or other tubular heat exchanger without cutting a hole or grove in the entire circumference of the tube. The apparatus includes an eccentric or a canted guide that is positioned within the end of the tube to guide the tool holder having a grove cutting tool mounted on it. The guide offsets the tool holder and the cutting tool from the centerline of the tube so that the cutting tool only cuts into a portion of the inside surface of the tube.
