Your not going to be able to drill thru an extractor bit by hand like that. Youll have to tear it down and take it to a machine shop to have it drilled and retapped. This usually teaches a very good lesson, ive broken tons of extractor bits in turbo manifolds, luckily I worked at a machine shop. Good Luck.
