It dosen't have so much to do with the thickness, but the hardness of the steel. If it's pretty hard, you might want to step up to a 135 degree point. But if it's just mild steel, it will probably just slow you down a bit. Either way is fine, can't hurt.

If you can do split points on your Drill Dr. I'd definently consider doing that to most of the bits.
