There is a great need to drill a hole of small diameter, for example, in a circuit board for radio elements or somewhere else. A screwdriver is usually used for this. And if you decide to clamp a thin drill into its chuck, then it’s unlikely that it will work. Anyone who has encountered this will understand me.
The fact is that the clamping jaws of any drill or screwdriver have an initial gap, which cannot be reduced even by the strongest tightening. Plus, this gap increases if the tool is often used and if your tool is more than one year old, and as a result, the gap distance can reach 1-3 mm.
The classic way out of this situation is to use a special drill with a collet chuck. Which is designed for installing small diameter drills into it.
What to do if you don’t have one at hand? How to secure a miniature drill so that it does not wobble during drilling?
The way out of this situation turns out to be quite simple.
Will need
- Copper wire 0.2-0.8 mm thick.
- Miniature drill to use.
If there is no wire, you can use solid or stranded wire. To do this, remove the insulation from it and select cores of a suitable diameter.
A way to secure a thin drill bit in a screwdriver or drill chuck
We take the wire and wind it tightly, turn to turn, onto the tail of the drill, which will be clamped.
Wrap it up and bite off the excess with wire cutters.
The drill bit is ready for drilling. Thanks to the layer of wound wire, the clamping diameter of the drill evenly increased.
We clamp it into the chuck of a drill or screwdriver. There is no need to overtighten.
We drill a hole in the board, metal and wherever we want. Drilling goes well, there are no strong beats.
In this way, you can use thin drills from 1 mm to somewhere up to 0.2 mm.
This trick will help you out in a difficult situation. See you again!
