とにある。Generally, this type of drilling device is constructed by attaching a drill to the tip of a water supply unit and connecting a driving machine such as an electric drill to the rear end. Conventionally, drills have been mounted using a screw type or a tapered fitting type in order to secure the drill and prevent water leakage. For this reason, it took time to attach and detach the drill, and water often leaked from the fitting part.This invention solves the above-mentioned problems of the conventional example, and makes it easy to attach and detach the drill, and also allows water to leak from the fitting part. The purpose of this device is to provide a drilling device that does not allow water to leak.The feature is that a shank is formed at one end of a shaft rotatably provided in the water supply unit body, and a connecting hole is formed at the other end. A seal part and a rotation prevention part are formed on the side surface of the connecting hole, and a seal part and a rotation prevention part are formed on the mounting part of the drill. A sealing member is provided on either side, and the mounting portion of the drill is removably mounted in the connecting hole.
