I have only had the drill set for a couple of week. I have used the smaller drills on several steel projects. They have cut as expected (after using a center drill to keep them from wandering). It helps to use a little cutting fluid to keep the drill cool and cutting. Their duribility is supposed to be better than that of regular high-speed steel drills. I will have to wait and see on that.
Nice drill set
