It's a precise jig for drilling out the broken bolt - designed specifically for our engines..

The detailed video on the site is quite informative.

Good luck!

Great piece of kit but on the left bank I have only 1 stud removed, the other 5 snapped off.
The right bank has 3 studs removed but they are all in a group. I'm not looking forward to this at all.
