ABSTRACT:
A tool for obtaining access through a gate can to the end of a valve stem of a valve in a buried water main. The gate can extending from the valve bonnet to the surface may be filled with silt, dirt, or debris. The tool is cylindrical, having a helical rib and cutting edge providing an auger so that by turning the tool the debris within the gate can can be cut into and removed by the tool. The tool has a fitting at the top adapted to receive a socket on the end of a manual operating tool which is the same tool that can be used to engage a fitting on the end of the valve stem for operating the valve.
