I believe you are familiar with the idea of drilling holes in ceramic tiles. For example, the most common hook for placing towels in the bathroom needs to be drilled through the ceramic tiles. We also often see tile cracking during the drilling process, so how to avoid cracking when drilling tiles? Then you need to pay attention to these points, let’s take a look at it!
1. Punch location
① Before drilling holes, check whether there is a hollow in the tile. If there is a hollow, you need to reselect the position, because drilling holes in the hollow can easily cause the tiles to break and fall off. In addition, pay attention to the corresponding positions in the wall and avoid beams, columns, and water and electricity lines.
② The drilling position should be chosen at the joint of two tiles. If it is not suitable, it can be in the middle of the tile. It must not be chosen at the edge of a certain tile, as this will easily cause the tile to break.
③After determining the location, mark it with a pen or pencil.
2. Choose the right tool
Drilling may use impact drills, pistol drills, electric hammers and corresponding drill bits. Which one to choose and how to use it are all very particular.
It is generally believed that the drill bit for drilling tiles should not be a concrete drill bit, but a tile-specific drill bit or a glass drill bit (it is said that each can be purchased for 5 yuan in the building materials market).
The drill bit should be a hollow tube-shaped emery hole drill bit, followed by a bow-arrow-like ceramic tile hole drill bit. Currently, there are arrow-shaped drill bits on the market that are specially designed for drilling ceramic tiles, which are more convenient and faster.
3. Control the speed
In addition to tools, controlling the rotational speed is also critical. The speed should be low at the initial stage of drilling, and the speed can be increased appropriately after the glaze is drilled.
When using an impact drill, turn off the impact function and replace it with a ceramic tile drill bit. Generally, the impact drill has a flat drill bit. Turn to the flat drill bit first, and use low speed to gently remove a small amount of the glaze on the tiles. block, and then penetrate the tile layer at high speed, and then drive to the impact drill to continue drilling.
4. Control the size of brick holes
When using a glass drill bit to drill holes in ceramic tiles, first make a small pit in an oblique direction. If it is a big blowdiameter holes (such as smoke holes), use a drill to first make a circular mark on the tile, use a tile drill bit to drill a circle of holes around the mark, and then use the drill to make the operation easier.
5. Continuous watering
Water should be added for cooling during the drilling process, otherwise the drill bit will easily burn.
6. The punching force should be balanced
When drilling holes, do not use excessive force, and do not shake the drill from side to side.
7. Unblock the drill bit
After each hole is drilled, remove the drill bit and clear the blocked hollow part of the drill bit. This step is especially necessary for full ceramic tiles.
8. Heavy bolts should be long enough
Insert the expansion plug (plastic expansion tube) into the punched hole, and then you are done. Some masters said that if heavy bolts are installed on ceramic tiles, bolts that are 3 cm longer than the original bolts must be used, otherwise it will be dangerous.
9. Be careful when using electricity safely
Wear insulating gloves when using a drill.
