My terrible terrible bolt conundrumby HansWell, as I was posting on Patreon, my efforts to remove this damn bolt in my cylinder head have gone amusingly bad.
But I can confirm a couple of small points.
A carbide bull-nosed burr can definitely cut through an ez-out.
A custom turned drill-guide will make it nice and centered, worked GREAT.
When you get past the bottom of the offending ez-out, the rest of it just falls right out.
A carbide burr in that kind of situation, breaking through into open material, sometimes can wedge and break.
I now have about a 1/4" length of a 1/8" diameter carbide burr wedged in the bottom of an even deeper hole.
Alum really doesn't work if you can only apply a few drops at a time, evaporates too quick when you add heat.
