I have acquired some old MT drills, and several have been rather abused in the past and the tangs are twisted. What is the best way to fix this -would heating them up to forge them back into shape cause problems with hardening? I had considered cutting the ends off the drills and cutting the end off an old MT adaptor to provide a "bung" that could be used for pushing the drills out with, but then I thought about how hard this might be. Any suggestions?
