If there is enough flute length left when it breaks, you may be able to re-grind the cutting faces.! :stir:

Dave,
I'm surprised you didn't break it by just looking at it.

I still have, somewhere in the depths of my workshop, the 0.004" drill bit that Cincinnati were giving out at the 1960 something MECH show. We didn't believe there was a drill spindle fast enough in those days!
