It is not always possible to make an ideal hole in thick rubber without torn edges, even with a drill or a probe, since rubber itself is not a very good material for processing. There is one simple (to the point of disgrace) life hack for drilling rubber of any thickness with an unusual “drill”, which can be made in 5 minutes.
What will you need?
- Telescopic antenna from an old (or new) radio or tape recorder.
How to make a hole in thick rubber without a drill or punch
The first step is to disassemble the antenna. Everything is done very simply. You can use wire cutters to bite off the top knob, then use a hacksaw to cut off the fastening so that there are no jams. After this, all antenna elbows are simply removed from the opposite side. And it turns out about 5 “drills” with different diameters.
Well, then we clamp what we need in the screwdriver chuck.
And we drill thick rubber at low speeds.
It would be a good idea to use lubricant in the form of a drop of motor oil.
The result is holes of different diameters, absolutely smooth and without torn edges.
These “drills” can drill not only rubber, but also any other similar dense and elastic material.
