Precautions

The screw is easy to loosen due to too much vibration when drilling with the electric hammer, which is a normal phenomenon. You can continue to use the center drill after positioning it.

The product is only suitable for use on electric hammers. The handle of the post handle should match the chuck of the electric hammer (round handle and five-pit handle). Please choose carefully, thank you! ! !
note! ! The wall hole opener is used on the electric hammer. Be optimistic about the clamp handle of your electric hammer. It is not a three-jaw electric drill or impact drill. Please distinguish the machine.

The electric hammer is only used to hit brick walls and cement walls, but not steel bars, tiles and stones.
If there are tiles on one side of the wall, you have to use a tile opener to make a hole in the tile first, and then use a wall opener to make a hole. It is recommended that the tile opener is one size larger than the wall opener!
