Amazing bits!!!

I bought this set almost a decade ago. I mostly use on drill press 95% and occasionally with a drill .05%. They have drilled 1,000's of holes in every piece of steel imaginable I do use oil. There has never been a bit that didn't do the job. They are still my best set. Only issue ever I bent the 1/2" bit at the base using a drill my fault. I recommend 100%.

Broke after drilling 4 rivets

Bought 2 drill bits this morning, and the first snapped after drilling out 4 rivits. Not very impressed with the "6x longer life" at that rate some drill bits would have to break before contact.
