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!
