Drill bits, what's good?

[TechNova]

drill slow and use pressure, The heat is removed with the chip, if you are not making chips you are just rubbing creating heat that destroys the bit. Pilot drilling is also hard on the next bit. I make a dimple with 1/8" then use the final size. I have been using Max Winter Drill Bit City, don't know if he is still around haven't bought any in a few years.
