How to punch holes in ceramic blank?

1. Pre-calibrate the position to be punched.

2. Level of protection. (Be careful not to have water and wires at the corresponding positions on the wall.)

3。 Ceramic tile perforated glass drill. Suitable for all tiles. Of course, half porcelain can be made without porcelain. The top of the picture seems to be rusty? Um ... . )

4。 When drilling a hole on a ceramic tile with a glass drill, first make a hole obliquely; Otherwise, the tiles are too smooth to be positioned; Or not all tiles, just make a small hole with nails; If you want to be more precise, you'd better cover it with a board (this is a tile strip) with holes (the right size) like mine.

5。 In fact, the positioning orifice plate can be removed by making a shallow mark on the sleeve, and then. Prepare a water bottle in advance, drill a hole in the bottle cap and fill the bottle with water. Then, when drilling, water should be injected into the contact part between the drill bit and the ceramic tile at the same time; Especially all tiles, there must be water. 6。 There is no need to change the impact bit. Drill through the tiles and continue to drill the screws to a certain depth. Pay attention to drilling holes, remove the glass drill bit, and dredge the blocked hollow part of the drill bit. This step is especially necessary for all tiles.

7。 Insert the screw into the hole.
