One of them is to repair things that are not too heavy. You can drill holes in any direction (but you cannot use bone structures). If you need to use internal expansion screws (implosion tubes), concrete walls are better used, but the perforation strength of mortar walls is insufficient. Expansion screws are generally used directly without instructions in 8 mm and 10 mm. If the 6 MM hole tool fails, screw the expansion tube into the hole to take out the expansion tube, and fill the gap between the expansion tube and the hole with a thin piece of wood. 6 expansion screws can usually be firmly fixed, but the ceramic tiles and wall tiles have a certain thickness of cement Tube Assembly Machine layer when tiling, and the materials of these two parts are very good. Relaxed state when tightened. If you use it at home, And the drilling capacity is not very high, you can buy a light electric hammer to use as an electric hammer or electric drill. If a hole is punched on the surface of the explosion-proof glass, the entire glass may be damaged. In the plasterboard wall, there are two drill holes to choose from. Used to fix heavy objects, such as TV sets, need to use metal detector studs to locate the surface of the rack, drill into the rack and fix it with expansion screws. Perhaps because of the power of terminal support. When tightening a 6 MM expansion screw, the combination of the sand wall and the expansion screw is easy to loosen, so there is a correct way to loosen a screw first, and then hammer into an expansion tube. If you want to drill a hole in the surface of the tile, but also want to drill a deep hole, then if you can't drill a deep hole, you have to use an electric hammer. As far as the perforation of the wallpaper surface is concerned, the wall material must be distinguished, whether it is a solid brick wall or a hollow plasterboard wall.
