There isnt enough meat in an insert for a helicoil, you would have nothing left after you drilled it unfortunately. This is oddball but you could possible get an M7x1.0 tap and try converting it to M7 (may or may not work lol)

Thanks for all the suggestions. Its one of the climbinb wire inserts and I normally swap between hb and sb setus so epoxy is out. Oh and its a borrowed prototype (sorry Al). Think Ill check with a buddies shop.
