Impact drive bits.
For a long time I was looking forward to find an impact drive that has small slot bits ad was not finding it. As I already have an impact drive, but with big bits, I have decided to search only for the necessary bits (without the complete tool). I have finally found this ones and after being sure that they fit at my existing tool, I have decided to buy them. The received bits seems to be very strong, with a copper finishing, what is great. The item arrived in less than a month. Very good result, considering the current pandemic era. The item is just as expected. So, no bad surprises.
