How to drill holes in ceramics?

Preparation tools: impact hammer; Hammer and sample punch or steel nail; Marker pen; Measuring ruler; Sealing tape.

Step 1: Mark the ceramic surface to be punched with a marker pen, and punch a small hole with a steel nail.

Step 2: Stick the transparent tape on the ceramic surface horizontally and vertically, and mark it as a point to prevent it from breaking when drilling.

Step 3: Select the impact drill bit with the required diameter and install the impact hammer. Start drilling slowly and cool the drill bit with cold water if necessary.

Step 4:? Align the marked impact point vertically and start the impact hammer with appropriate pressure. Don't push too much, you can penetrate the tile smoothly with slow force. After penetrating the tile, you can push it hard until it reaches the required depth.

Step 5: slowly pull out the impact hammer and tear off the transparent glue, and finish.

Matters needing attention in ceramic drilling

Stick the tape on the marked place and stick it in a cross shape. Adjust the drilling machine from drilling state to normal drilling state. Turn the speed to the lowest gear. Adjust the depth limiter. Don't drill too deep holes in the wall, so the plastic expansion pipe will be stronger.

If the opening position is far away from the ceramic seam or edge, for example, the hole is basically punched near the center of a brick, as long as the smooth glaze is slightly pitted at the opening position with a sharp tool in advance, then the hole can be drilled. ?

If the opening position is near the ceramic seam and edge, first use the electric drill (turn off the electric hammer function of the impact drill) to install the cemented carbide drill (cylindrical head) for drilling glass, and then drill and grind the 45-degree angle at the opening position. After polishing the glazed surface, gently shake the electric drill while drilling (to prevent the drill from getting stuck), and rinse it with water to cool it (to prevent the drill from annealing, another person is needed). After drilling through the tiles, continue with an impact drill.
