Just make sure to use the oil use a good powerful drill and steady pressure.
You start off by drilling a small diameter pilot hole and then drill gradually larger holes until you get.
Step drill bits are designed to drill holes in sheet metal and other thin materials.
This can cause corrosion rust to form in and around the hole.
Drilling into galvanized metal is no different than drilling a hole in standard carbon metal with the exception that the protective zinc coating does not protect the drilled hole.
It s essentially the same as drilling normal metal.
