As a result, the work performed is of poor quality and with a great waste of time. But after a while, more convenient bits were invented. In the store they are marked with a pH. Each fixture has its own thread, so as not to be mistaken, there are digital indicators. There are values ​​that look like this:

  • 0-2 mm.
  • 1-3 mm.

This is necessary so that their useful life does not end after a short period of time. Such nozzles can be of non-standard length (up to 15 centimeters). In everyday conditions, difficult situations do not always arise, but in the process of collecting furniture there are corners to which it is not always easy to get with standard tools.
