Removing a Tap with No Visible Screw: 7mm Deep Hole, Hammer & WD40 Techniques Explored

There is no screw, only a round hole about 7mm deep, in which I cannot see the thread; I tried to pull the hammer off, beat it up with a hammer, hitting the sides with a hammer, poured it into the hole WD40 and all to no avail.

Because it's a Germanic cock.
You remove the knob by unscrewing the entire head.
Add a photo from the side ...

There should be a screw there. If it is not, it means that it is unscrewed and the tap is stuck on the multi-body. As it is all delicate, I recommend that you drip the hole with penetrating fluid, e.g. WD, and wait a few hours.
It should be easier after that.

It baked and covered with limescale. First try to dissolve the limescale with acid, then WD40. Finally, make a lever and pry it out.

I can't believe I can see it, don't you really have any other tool besides the hammer?
If not a hammer, try an ax - you will definitely take it off
But seriously, this cock is screwed on, post a photo of this "hole" and the matter will be clear.
By hitting the chrome hammer directly, it is reliably re-electroplating ..

And I see a broken axis in the tap hole The whole is screwed out together with the head

You can't see much in the photo, it looks like an imbus.

I haven't seen a ginger in a place like this yet. Can you provide a "pattern"?

it looks exactly like a disassembled axis and it is not, of course, the hexagon socket, but the hole, as I wrote, is round
all with the head, I understand that you need to unscrew these two large screws under the taps and it will give me something ...

Then you will unscrew the faucet from the sink.
If the axis is actually there, you have to unscrew the HEAD together with the tap. I don't know how else to explain it.

How to do it? will it take the head with it by turning the knob all the way to the left?

It should, or if it is screwed tight, rather the tap will work. But always positive, because at least it will go away
Only if you have to catch it with a key or a frog, then cover it with a rag, because you will scratch it completely.

Almost 10 days have passed. Is the cock pulled off?
If so, I'm curious in what way.

You could also drill this pressed part of the axle and remove it, and then put the hammer on the glue.

You can also pour concrete, then it will not "let go".
I am more wondering why the author of the topic did not simply call a plumber, who would probably do it in less time than putting the topic on the forum.

Maybe the need to remove the tap was not very urgent, the author was in no hurry, he likes to fix something at home himself and does not want to pay a plumber 100 zlotys just for taking the tap off because he knows how. Sometimes it is enough to ask how something is dismantled and further repair is no longer a problem, but you will save some money.
I also ask about many things on the forum, sometimes a specialist would know what is broken before coming to me, and I dig the Internet and fix for 2 days, but thanks to this I will always learn something and save. In addition, I watched the "Fault" program and now somehow I do not want to call any specialist. I don't know if it's right, maybe this program is set.

You are absolutely right, Poles are plumbers, mechanics, electronics etc. just watch a video on youtube or create a topic on the forum and we already know how to do it, but unfortunately it is not good for the economic situation,
imagine that everyone sews clothes, makes shoes, bakes bread, repairs a broken washing machine, replaces brake pads in the car, etc.
At the time that the author lost on assuming the topic, reading the answers, analyzing them and not to mention hammering on the chrome, he could do what he can do best and earn much more than, for example, PLN 100, unless he is unemployed, that's another thing

It's just like that with us. There are countries where people work in the professions they have learned or do the work they are interested in, thanks to which they are good at what they do, they are willing to broaden their knowledge, so they are up to date, and they have a lot of satisfied customers and good earnings. They don't have to know about other things - if something goes wrong, they call a specialist who also knows what to do and they pay.
But with us and a trusted professional, it's hard to work in your own profession. Everyone is up to it on their own.
It seems to me that among all this mess, electricians are still in a pretty good situation - many people, however, are afraid of electricity, do not want to kill themselves or anyone, they do not know about it (electricity is not water that you can see where it is dripping and where to repair), thanks why do electricians still have work. Because just any DIY enthusiast will take care of plumbing.

It is not always possible to take overtime at work and not always pay for it.
The pleasure of hobby work is that you are not at work and do something else. Thinking like the one presented by a colleague can lead us to a society of specialists in a narrow field, but completely unable to cope in everyday life.
