The one time I tried HF step bit it didn't work right out of the package, mild steel, barely put a dimple in the piece. I always set the drill press to the slowest speed, but these cheapy drills and presses don't have slow enough speeds not to over heat bits, got to save the old school one people are trashing for this new crap. While my bench top drill press is an import, I have had it for 33 years and I got it second hand, has a reasonable slow speed.
