Broken tap in cast iron... anyway to drill around to get it out?

[Dave Smith]

Yes, I know. But, I could not find a carbide grit hole saw at 5/16" or any other hole saw, at least not easily available in that size. All other hole saws were much larger. I knew it was a once and done bit.. just commenting on the fact that the cheap ones lasted 30 seconds or less, the better quality one lasted much longer and still useable. Even after using it on a material it was not mean for.

the main thing is that you got the tap out and fixed your hole--good job!!

Speak for yourself.

I was always happy when one broke.
