Best bet for you to have a go with is a self tapping one

Rather like this solution. Drill 9/32 drill (titanium) accepts M8 insert modify screw driver if needs to insert it. Thank you

Internal thread size: M5 standard metric coarse
External thread size: M8 x 1.0mm
Recommended pilot hole size: 7.1 - 7.6mm

Is there enough meat to take an M8 insert?

Thanks for all your replies and kindly offers. I learnt something about not Helicoils but 'inserts'.
