Note:
1. When the surface of broken screws is smooth, you need to drill a hole first. Otherwise, the drill bit will slip.
2. When drilling the hole, it must be vertical and slowly. Using this drill bit upside down, the deeper the hole you first drill, the easier it is to take out.
3. It is best to use an electric hand drill instead of a hammer drill. It must be slower during use.
