When using electric hammer to drill holes in ceramic tile wall, we can try two relatively simple operation methods to avoid ceramic tile damage. One is to simply treat the ceramic tile surface first to prevent cracking. The other is to use a special tile drilling tool to make holes, and then use an impact drill to expand the hole and drill deeply.
1. How to treat the surface of ceramic tile
First remove part of the porcelain surface at the drilling position. After this treatment, the drill bit will not directly contact the porcelain surface. The specific operation methods are as follows.
First, make a cross mark on the position where you want to drill a hole, and then gently tap the porcelain chip on this marked point with a cement steel nail. At this time, two points need to be paid attention to.
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 incline the steel nail to the ceramic tile to form a certain angle between them, which is conducive to breaking the surface of the ceramic tile.
The second point is that the strength of knocking steel nails should not be too large. If the porcelain is knocked hard before it is broken, it is easy to cause porcelain collapse on the surface of the ceramic tile. At that time, what is broken is not a point, but an irregular sheet.
Next, continue to knock around the marked point with steel nails until the porcelain surface at this position gradually falls off to form a small pit. At this time, the drill bit can be pressed against the exposed point for drilling operation.
2. How to use special punching tools for ceramic tiles
The special tile drilling tool is different from the ordinary impact drill bit. Its shape is more like the arrow cluster of bow and arrow. It can drill holes under the condition of ensuring the integrity of porcelain surface.
However, such tools cannot be directly used on large electric hammers. They need to be used with a slightly smaller electric hand drill. At the beginning, the drilling speed of the electric hand drill needs to be adjusted slowly to prevent the bit from sliding or breaking.
When the texture of the lower part of the ceramic tile is exposed, adjust the drilling speed to make the drill completely pass through the ceramic tile layer. Then replace the electric hammer and impact drill bit according to the required hole-diameter, and continue to expand the hole and drill deeply.
Another tool is the tile opener, which is similar to the barrel shape. When it is used to open holes for ceramic tiles, it needs to open obliquely at a small angle. However, due to certain requirements for technique and technology, it is best to hand it over to professionals for operation.
3. Other relevant precautions
When making holes for ceramic tiles, many dusts harmful to the body will be produced. In order to suppress the flying of these dusts, it can be washed in time with water, or professional drilling dust-proof storage bag can be used, which is relatively safer. However, no matter what method is used, it is necessary to ensure effective safety protection during construction operation.
