It is most important that keep the drill centered. Guide the drill at
an angle until you get hole in the right location and then slowly
straighten the drill. Do not break the drill. Drill the screw all the
way through.

If you think loctite may have been used then heat the area until smoke
shows the loctite burning.

When cool insert the extractor and tap downward to make the tool grab.
This should remove it if you kept the drill centered.

If not drill the hole through with a root diameter drill as long as
you can keep it centered. If you can Re-Tap.

If this still fails then purchase a thread insert and follow the
directions.
