[TR] drill bits thanks!

[Gary Nafziger]

wow I learned a lot through the responses to my drill bit question.  I always
did drilling under the impression that higher speed and more pressure on the
steel the better.  Also I've rarely used a lubricant. 

 I  had been curious
about why some bits lasted much longer than others and it must have been that
accidently I slowed down and used more appropriate pressure at that time. 
thanks for everyone's input.  very very helpful and another reason this list
is amazing!
