I don't know if anyone has tried this or not, but it worked for me. I had a part I was working on this week that had some 6-32 tapped holes in it. Everything went good until I broke a tap off. I've used carbide ball nose endmills to drill out a broken tap, but I didn't have one small enough. Then, I thought I would try a carbide burr. Worked like a charm! Ran it about 3000 rpm, plunged it down .001 at a time, and I had it drilled through the tap (about 3/8 long) in a few minutes.
