I've had this set for nearly 3 years and I'm happy with them. None of them has snapped nor dulled. I've used them to do some tricky stuff, such as hand drilling out tapered steel pins that go through steel pulleys and shafts...this tends to be a drill breaker since you're going through different pieces and types of steel. I've repeatedly had a bit jamb in a hole on breakthrough, and the drill just stops, rather than the bit breaking. These are good strong bits. I've given a set to each of my kids, and they seem happy with them as well.
