what sized drill bit do i use, says M6 on the shaft

sorry for such a simple question

Can't be certain off that picture, but it looks the same as a Rawlbolt and for a 6mm rawl you use a 12mm drill bit.
To be sure measure the expanding case O/D and drill at that size:

Does it not say the drill size on the outside ?

This I'd say, I slacken the case so its not expanded at all then measure itor if im being lazy I'll other up the masonary bits to the end and see which look right

Hold drills in line with the end of it until you find one that's the right diameter. Just use your eyes.
