So I broke off a M3 tap in a block of 0.5" aluminum.

Its tip is barely emerging on the far side, and broken below
flush on the feed side.

Got a hammer and a good solid punch?

I've broken a few numba 6s trying to tap 1/4" 316 stainless.

But each time I got lucky and got them out using a very small punch
and using it to tap the little bit of exposed tip so that it unscrews
a little bit. Once it lets go it can be worked out fairly easily.
