The wall hole saw connecting rod is a rod-like tool used to connect the wall hole saw with other tools. It is typically made of hard alloy, with the handle including square and round shapes, featuring an integrated design that is hard, wear-resistant, and durable. One end of the connecting rod can be inserted into the hole of the wall hole saw, while the other end can connect to other tools such as electric drills and reamers. By using the connecting rod, it is suitable for operations like drilling and reaming on materials such as cement walls, concrete, brick walls, and stone, saving time and effort.
