Enamel drilled, change the drill bit drills into the normal metal. If you want a small hole, first drill a hole of small diameter, and then it rassverlivat thicker drills. Don't forget to cool the metal and drill slowly, if it heats up and the surface will go "whitening" - the drill bit will be blunt in the first millimeter, as cast iron becomes harder than tempered steel.
If you need a large diameter hole, make a jig from a piece of plywood with a Central hole. First drill through the jig to remove the layer of enamel pervym drill bit for glass or tile. Then remove the jig and drill a conventional drill on metal. Note that the holes in the jig should be located at a distance of not more than 1 mm, then the disk will be removed easily.

If it is a part of enamel is split off, close the edges of the holes with decorative chrome Cup of appropriate diameter.
When you drill a hole in cast iron tub, cover the bare surface of the cast iron sealant or epoxy glue, or after the installation of the mixer, the enamel will begin to appear rusty streaks.
