How to fix a thin drill in a chuck

There is a great need to drill a hole of a small diameter, for example, in a circuit board for radio elements or somewhere else. For this, a screwdriver is usually used. And if you decide to clamp a thin drill in his cartridge, then it will work out. Anyone who has come across this will understand me.
The fact is that the clamping jaws of any drill or screwdriver have an initial clearance, which cannot be reduced even with the strongest tightening. In addition, such a gap increases if the tool is often used and if your tool is not one year old, and as a result, the gap distance can reach 1-3 mm.
