One of those days where everything goes wrong:
Broke a favorite t-handle tap, dented in the surface from only light tapping, the lefty swirl ones went in but did nothing but round off.
That old screw end is in there.
Double nut from back didn't work, stub kept snapping easily, din't have correct tools
Tried to drill out larger. In one second the TiN bit snapped off. Getting frustrated.
