Drilling, along with machining is all about speeds and feeds. Bits are made to cut. If you don't have chips or curls coming outta the hole u aren't feeding enough. I run all my bits as slow as I can. Different materials and different sized bits have different speeds and feeds. If u try to run those carbide blazing fast on a drill press I'd imagine that's why they don't last long. My 1/8" has lasted a year or more and is good as day one
