Let's see, if I wanted to drill through a piece of tile, which method
would I choose? Hmmmm, I wonder.
Well, I've certainly used a punch and very gentle tap
with a hammer to mark the spot before drilling tile.
Done it many times -- to avoid the bid skidding off
the glaze. It's not the only way to break through the
glaze and prevent skid but it does work and very well.
Making a dimple in a very soft metal like brass won't
take much force at all. Drilling a hole in it will
require a lot more energy.
If you can't make a tiny dimple without cracking the
thing, I very much doubt the item will survive drilling.

How thick is this brass material that it would make a difference wether you
drill in square to the surface or straight down ? depending on the thickness
and the angle I might drill in square with a slightly smaller drill and then
straight down with the full size.
