I have read many posts on sites like this and machining forums about quality drill bits. There are so many brands but also many of them are simply too expensive to justify the set. I ended picking up some Norseman bits in screw machine length and have been super happy. They come in the Huot metal indexes which are really nice. I also added a drill doctor 750 that should keep me covered. And a bonus is that these are made in the USA. I believeall of their products are with the exception of the dies in the tap and die sets. Here
is some more info If anyone is interested.
