Frozen milling cutter holder


Need to get his loose.

Tried elbow grease.
Heated it with propane several times. 
Tried a hand impact.
Drilled the back of the hand impact to take an air hammer shank.
Tried drilling it out with a left hand bit.
Did not come loose so switched to a regular bit.  Went through a couple they dulled.
Tried an end mill in the drill press to get the sloped sides left by the bit.  Maybe ran it too fast.
Placed it on the floor and drilled with a cordless drill wobbling the bit to get it to bite.
Placed the cutter in the big vice and twisted the hex part with a big crescent.  
It came loose!    
But now the set screw hole is too large to be useful.
I am going to drill a new one on the other side of the holder.  There is enough meat left so it should work.
