Lol I use Mibro cutting fluid/coolant when drilling. The fluid has a low burning point and even a hand hacksaw will make it smoke, Well its not realy like smoke, theres a difference between just vaporizing the fluid and smoking it. Ever open the door on a CNC lathe/mill and see the mist? Kinda like that. Lack of lube didnt kill this bit. I tried to drill threw (Not knowing) hardened steel and killed the bit. Whos hand is messed up Ed? Are you talking about the cut on your hand? I got much worse when working in the machine shop, Whent to pull a razor thin filing stringy thing off the cutting head in the lathe (Bad idea) and sliced right to the bone.
