Love them! Have been cutting like common steel is butter. They have no-slip shanks so you can chuck right up to them without worry and even the smaller bits haven't broken due to not having to put pressure on them to make holes. I love many tried and true Bosch Tools and bits and these are no exception.

Make sure to go slow and use curtting oil. Keep the heat out of the bit and the metal. Works on wood too., but cheap bits work on wood. Drilling steel is when you want good bits lime this.
Note these bits are hard. All bits that are hard, are brittle. take it easy and the will last.
