I did the maths....You are correct, the 1 is almost wore off of this bit it has been used so much LOL.
If You are talking drilling free hand You'll actually inevitably create a larger diameter hole, possibly oval in shape at the entry point.
A drill press might be a good idea.
Drill little by little and check depth often.
But I'm talking generally, I have no clue how magnesium behaves.
Well, that depends on the outer thread diameter the insert features, doesn't it?I usually don't even drill the hole out if in Mag or Al, just run the tap in, good to go.

A boogered M5 is fine for a direct M6, but not for a M8 unless the hole is really slapped out.
But there are exceptions, a coworker managed to thread a M10 into 6.7mm holes, the M10 tap broke eventually because it is coarser than a M8.
The mill didn't mind at all, it just kept running the wrongly replaced M10 into the 6.7mm holes not knowing it's not a M8.
I guess the coworker didn't know the difference either.
Another tip while I'm thinking about it .You are better off to use a spiral point tap than a fluted tap on not ferrous metals .Thread oil works but a product called
"tap magic " is better .A little can is not costly .Get the one that says for aluminum .
