Abstract
The utility model relates to a welding hole saw, which is mainly applicable to drilling wood holes. The connection of a central drill and a saw body of the existing similar product is a separated structure, which is realized by thread fit of a screw nut and a thread on the central drill; so the product is easy to loose during the hole drilling, and the usage is not convenient enough. The welding hole saw includes the central drill and the saw body, one circle of an opening end of the saw body is provided with a saw tooth, which is also characterized in that the central drill and the saw body are welded into an integrated structure. Thus, the welding hole saw has reasonable structural design, convenient, rapid and reliable usage and no loose.
