A:  I would suggest a carbide bit for cast iron

A:  Yes they're very good at drilling into metal.

A:  When properly lubricated, they can drill through mild steel. If the cast iron is ductile iron or malleable iron, given the graphite content of those irons, you may be able to get away without a lubricant. That said, lubricate if you can.

A:  It might depend on how many holes you want to drill. Cast iron is not very hard, but the bit will get hot if you are doing many holes.
