How to punch holes in bathroom tiles
2. Draw an intersection accurately with pencil positioning, and then cover it with transparent tape.
3. Electric hammer is used for drilling, and 6mm drill bit is generally used. The wall of the drilling rig first destroys the glazed surface of the ceramic tile, and then gradually becomes heavier, and the depth is slightly deeper than that of the plastic nut.
4. After drilling, select the appropriate expanding tube to bury and tighten the required device objects.

Precautions for punching ceramic tile in bathroom
1, select the appropriate tool.
Drill holes can use impact drills, pistol drills, electric hammers and corresponding drill bits. What to choose and how to use it are all exquisite. It is generally believed that it is best not to use a concrete drill for drilling ceramic tiles, but to use a special drill for ceramic tiles and a glass drill. It is best to use a hollow tubular emery bit, followed by a tile bit such as a bow and arrow head.
2. Control speed
In addition to tools, it is also critical to control the speed. The initial opening speed should be low, and the rotation speed can be increased appropriately after glaze drilling. When using an impact drill, it is necessary to turn off the impact function and replace it with a ceramic tile drill. Generally speaking, an impact drill has a flat drill file. First drive to the flat drilling gear, slowly and gently grind off a small piece of glaze on the tile, then drill through the tile layer at high speed, and then drive to the impact drilling gear to continue drilling.
3, control the brick hole size
When drilling a hole in a ceramic tile with a glass drill, first make a small hole obliquely. If you want to be accurate, you can cover it with a perforated plate (tile) (appropriate size), make a shallow mark and then remove it, and then pass through the hole to be punched. But remember: this hole must be larger than the actual hole 1.5-2mm.
Step 4 keep watering
When drilling, add water to cool it, otherwise the drill bit will burn easily. The operation is as follows: find a mineral water bottle → fill it with water → punch a hole in the bottle cap → water while punching → water the contact part between the drill bit and the ceramic tile (especially the whole ceramic tile, be sure to water it).
5, heavy bolts should be long enough.
The expansion plug (plastic expansion tube) is inserted into the hole, which is considered to be completely successful. If you install heavy bolts on ceramic tiles, you must choose bolts that are 3 cm longer than the original bolts, otherwise it is very dangerous.
