When using an electric hammer to drill holes in ceramic tile walls, we can try two relatively simple methods to avoid tile damage. One method is to first perform a simple treatment on the surface of the ceramic tiles to prevent cracking. Another method is to use a specialized ceramic tile drilling tool to drill holes, and then use an impact drill bit to expand the hole and drill deep. First, remove a part of the surface of the ceramic tile at the drilling position, so that after processing, the drill bit will not directly come into contact with the surface of the ceramic tile. Firstly, make a cross mark on the position where you want to make a hole, and then gently tap the ceramic tile on this marking point with a cement steel nail. At this point, two key points need to be noted. The first point is that the steel nail tip should not be too perpendicular to the surface of the ceramic tile. The correct way is to slant the steel nail towards the ceramic tile, forming a certain angle between the two, which is conducive to breaking the surface of the ceramic tile. The second key point is that the force of striking the steel nail should not be too strong. If the ceramic tiles are forcefully struck before they are broken, it is easy to cause porcelain to collapse on the surface of the tiles. At that time, what is broken is not a single point, but an irregular sheet shape. Next, use a steel nail to continue tapping around the marked point until the porcelain surface at this position gradually falls off and forms a small pit. At this point, the drill bit can be pressed against the exposed point for drilling operation.
