| Description: |  | The primary aim of this tool is to effectively combine boring and reaming operations in one tool and continuous operation. The lead screw helps pull the tool into the wood, while a gouge shaped cutter at the bottom of the body bores the opening hole - with the reaming cutter to follow. |  |
