4.3 mm holes, 20 mm deep

Yep, exactly. Ill order those drill bits, seems good value for money and keep for future if I ever need to do similar again.

Cool, if you look I think you can just buy 1 bit at a time for 99p all in or something from another seller, saves buying a box of 10.

I'll confirm what I've got if you want and send you?
