angle bit is NOT impact resistant at this time Wonder how I know I originally got it for adapters but not angle or Flex I got it in the mail today and was excited to start working on my projects and then I realized I couldn't get a shock motor in the space I had no problem I had the perfect attachment for the Job. The corner hitter broke in literally 15 seconds. The adapter worked fine but it's just a piece of metal you can hardly go wrong with it. I didn't use the flexible nozzle but as it is structurally less strong than the solid corner piece, I suspect it's not impact resistant either. If you use bits in your drill for light work like driving screws, this will likely work for you. If you're only getting it for its impact resistance, look elsewhere.
