What can I do if the drill does not go in?

When the impact drill uses the impact mode, everyone complains that the wall and concrete are too slow or not drilled at all.

The impact force of the impact drill is far less than that of the electric hammer. When using it, it must be forced to withstand. As long as it is not cast-in-place concrete, the following common things are: clay brick, cement mortar layer, ceramic tile (not all-ceramic, which should be opened with glass), cement bricks can be drilled in. If you encounter a bad drill, you can drill with a small drill and then change it.
Drill bit, in my experience, the general household is to install plastic expansion screws, 6MM and 8MM, generally do not have to change the drill bit.
