Si duran
Las compré para inoxidables y se soporta las cargas como todo con el uso prolongado van perdiendo filo pero dura bastante para su precio

So far, so good.
This set of drill bits had all the bits I needed for the job it was purchased for. At this stage they are handling the job and lasting. Looks like the right tool for the job, so far.
