Are there any threads showing? Could you get a bushing into what remains of the hole to guide a smaller bit for a starter? When that bit bottoms into free air you can stop and measure how deep you can go with the full size drill bit. That's some info you want!
If there's a little bit of the broken bolt sticking out of the hole still, you could thread a nut over the remnant and stick a bushing in that to guide a smaller bit. You really need to drill straight into the bolt. Lots of oil and sharp bits. That size bolt, you need to drill progressive sizes up to the final drill for the tap.
