I have to put the bathroom accessories, some go with screws since they are bronze brought from an old ship. My question is what type of wick I use and at what speed you have to do it.

Hello In addition to the recommendations that colleagues have given you, I would like to add that, once you manage to start drilling, you can cool the work of the wick by throwing water with some “carnival pommel” type container, that way you make sure that you don't know dilate the wick in full work and the porcelain tile cracks. It is advisable to start the hole with a widia wick of 5 mm and be enlarged to the extent of the liner to be placed. Cheers !

Hi Cristina, you should use a wick of the appropriate measure of "Hard Metal or WIDIA". well sharpened, (by a good mechanic), not as it comes from the factory, and with a hole hole WITHOUT REVERSE, in the center point of the hole, with a fine point and soft strokes marks the glazed surface of the ceramic, there you start with the wick , with a firm pulse but little load, (if you like the wick you give it water while it turns), and you have to be careful and firm softness when the wick comes out at the end of the hole, because that is when the pottery unbalances and can break, As I understand that they are placed, it is the best situation for firmness. luck

You can use 6mm plugs with not very long screws. The speed of the first is smooth, if you can make a small point to the ceramic so that the wick does not run when you make the perforation. Once the ceramic is passed, high revolutions can be used such as in a perforation in a normal wall. This work is delicate but not laborious. Regards
