A word of caution, if you drill bang on centre and straight, the stud will remain until the very end. At which point the remains of the thread will be drawn up the drill flutes wrecking the hole on the way....if you're lucky it will be ok for helicoil, of not you need something else...e.g the EzelokThanks for advice.
Head-off is probably a bit of a stretch for me, i am not in a good working space here but can see your reasoning.
I will try once 1st at re-drilling with good drill bit and re-tap to m8, if that doesn't work i do have the helicoil kit now as well. The pilot hole i have drilled is good except for going a touch too deep.
Thanks
Hopefully have an update later-on
