CUTTER CAPABLE OF CUTTING AWAY OBSTRUCTIONS DISPOSED ON THE INSIDES OF PIPES RANGING IN DIAMETER FROM APPROXIMATELY EIGHT INCHES TO APPROXIMATELY FIFTEEN INCHES OR FROM APPROXIMATELY TWELVE INCHES TO APPROXIMIATELY TWENTY-FOUR INCHES

摘要

A cutter is provided for cutting through obstructions disposed in the interior of pipes ranging in size from approximately 8″ to approximately 15″ in diameter or from approximately 12″ to approximately 24″ in diameter. The cutter has been reduced in size relative to known root cutters to be capable of being used with smaller-diameter pipes, but is sufficiently powerful to cut through obstructions, such as mineral deposits, for example, that known flexible cutters capable of being used with these smaller-diameter pipes are incapable of cutting through.
