Strong and effective, Bosch quality is at the rendezvous. Ten euros per chisel, it is not stolen! Sure, there are better but much more expensive. Then for casual work it's still a good choice, especially when we know that this kind of tool suffers a lot, we did not always want to spend much more to break the brick, tile or concrete! Think clean and oil them after use to avoid rusting. Good protective case comes with these chisels.
