What type drill/bit do I use???

i am going to put jack mounts on the front of my front bumper. what type bit do I use? Ive never drilled through a bumper before. All I have is a 9v battery drill. Any words of wisdom will be greatly appreciated.

Start with a small bit and work your way up to the size needed. Buy a 110 VAC drill.... they are CHEAP......and WAY more powerful than a cheap battery one.

I found the stock bumpers difficult to drill and used tungsten drill bits.

Pilot hole, step bit, cutting fluid. Done deal.

Do you mean mounts to hold the jack, or points to lift the Jeep using the jack? If you mean jack points make sure you drill all the way through to the frame rail and tie into that. The stock bumper is sheet metal and will bend if you try to lift the Jeep with it.
