How to punch a hole in the tile without cracking

Punching holes on the paved tiles seems to be an inevitable operation, but the success rate can be described as unspeakable, there are fan messages in the background to say some knowledge points related articles, that today Xiaobian focus on doing a science popularization. When we punch holes on the tile, the emergence of porcelain, cracking and other conditions is mostly caused by non-standard drilling operations. How to punch accurately and not afraid of brick cracking? The following 9 knowledge points to remember!!

01 Select a hole position
It is best to choose the joint of two tiles, if not suitable, you can be in the middle of the tile, do not choose on the edge of a tile, so it is easy to break the brick, too many failure cases in this.
Before drilling, check whether there is an empty drum at the tile, if the empty drum, you need to re-select the position, because the hole at the empty drum can easily lead to the breakage of the tile. In addition, pay attention to the corresponding position in the wall, avoid beams and columns, water and electricity lines.
After determining the position, mark it with a marker for more accurate operation.

02 Select the right tool
The tools needed for drilling are percussion drill, pistol drill, electric hammer and the corresponding drill bit, which to choose and how to use, there are specifications.
It is generally believed that it is best to use tile/glass drill bits for tile drilling.
The drill is best to use a hollow tubular emery drill, followed by a tile drill like a bow and arrow. At present, among the many tile bits on the market, Bosch recently launched a brazed diamond tile perforated bit, easily cope with high hardness marble, tiles, etc., indeed in response to tile drilling is to provide a good choice, of course, the price of this bit is relatively high, in fact, it is worth trying.

03 Control Speed
In addition to choosing the right tool, how to control the speed of the machine is equally important. The opening should be low speed at the beginning, and the speed can be appropriately increased after the glaze is drilled. When using a percussion drill, it is necessary to turn off the impact function and replace it with a tile drill bit. Generally, there is a flat drilling gear on the percussion drill. First open to the flat drilling gear, at low speed, gently grind off a small piece of the glaze on the tile, and then hit the tile layer at high speed, and then you can open to the percussion drilling gear to continue to chisel in. After the tile is drilled out of the hole, if the material behind the tile is concrete, an electric hammer must be used. Many machines now have stepless transmission function, which will be much easier to control.

04 Control the size of the rotating brick
When turning the hole, it is mainly necessary to tilt the drill bit in the direction at the beginning, grind it lightly, hit a small pit, hit a shallow mark and then remove it, and then hit the hole to be punched through. If it is to play a large aperture hole (such as smoke holes), use the drill to turn out the round impression on the tile, use the tile drill bit to drill a circle of holes around the impression, and then on the drill, so that it is easier to operate.

05 Control the punching force
When drilling operations, do not need to be too strong, let alone shake the drill from side to side.

06 Drill blockage should be removed
After each hole, remove the drill bit and dredge the hollow part of the blocked drill bit, especially for the whole tile.

07 Heavy bolts should be long enough
The expansion plug (plastic expansion tube) is not inserted into the drilled hole until it is done. A master said that if the tile is installed with heavy bolts, it is necessary to choose a bolt 3 cm longer than the original bolt, otherwise it is dangerous.

The above 7 steps can help you make a good tile hole, decoration is a technical work, a lot of processes, if the average person does not know the method and know-how, it will make their home changed a taste.
