I took it for work on objects where it is necessary that the necessary tool is always at hand. When you drill in bulk, you have to look for what you need, losing precious minutes of working time and not the fact that you will find it, because in the placer you can’t see the forgotten ones. Now, opening the box, I see that everything is in place, and there will be no cases that I took three pieces of unnecessary diameters in puffs, but did not take the right one.
