I'm not sure if a drill bit will work since the bit has to rotate clockwise to bite into the material but the plug has to come out counter-clockwise. I used a hacksaw blade to carefully cut through it, front to back, in a couple of places then used needle nosed pliers to pull out the pieces. Another way would be to use this, which can be found at Ace, Home Depot, etc.
Left hand drill bits are available and just for info left hand thread taps are available as well.
You are on the right track suggesting using a LH drill, however, you cannot use a left hand tap to clean out right-handed threads.
I once seen a rookie wannabe Machinist cussing all the china made taps, while the whole time he was trying to start a LH tap into hole with RH threads.
I pointed out that it had LH etched on his tap, he shore got red-faced & gave us all something to rib him with.
