   I was aggressively pushing a 3/8 HSS drill though a piece of 304 SS   
   round bar and I set the light cutting oil I was using on fire just   
   before I broke through.  I don't recall even blinking.  I just pushed it   
   through a little further to make sure the hole would be big enough.   
      
   Then I leaned forward and blew out the flame.   
      
   The amazing part to me is I drilled 4 more holes in some steel pipe   
   afterwards with the same drill bit, and the 3/8 pins went right on.   
      
   The fire doesn't surprise me at all.  Before I started I told myself I   
   should walk over to the lathe and grab the heavy cutting oil.  What   
   surprised me is that HSS drill is still a hole making machine.  Maybe   
   that shouldn't surprise me either.  HSS is known for being able to   
   tolerate some serious heat.
