I opened the collet full to the end. Inside is a ring, conic shaped on the
external surface, cilindric on the internal, with a longitudinal cut to
allow the bit get pressed by the collet. I hope not to damage anything...

"a" longitudinal cut? Dou you really mean that there is only one slit?
Good ones have three slits, heap ones have four (because thats much
easier to make) and expensive large ones have many. But only one
cannot be good because with one there is no way to kep the bit centered.
