Good Step Drills
After using titanium coated and cobalt step drills, I have to say I really like these Astro ones. They have stayed sharp and cut very well when widening holes. The coating on these is self-replenishing and so far that seems to be true as I've noticed no change to the color of the coating unlike titanium coated ones which quickly lose their coating. They also cut as fast as cobalt step drills I've used.Considering this is a 2 pack with a decent size range, for most people this set should cover all your step drill needs. I'd certainly recommend picking up a pack as once you have these in your tool arsenal, you'll find plenty of uses for them.

Definitivamente mas duras que las similares
Por fin logre perforar acero inoxidable sin que se estropeen en el tercer agujero! Solo enfríalas con agua para evitar el sobrecalentamiento!
