I call "foul"!

Yes, coffee grinders WILL wear out. I have one of those Atlas® brand
Turkish coffee grinders converted to a blk pepper mill and sold fer
waaay more than they're worth. I've had it fer about 15 yrs and it's
becoming less and less effective. I suspect is does not have hardened
burrs, like an older Zassenhaus (German) coffee grinder, I have.

Most coffee grinders have cast burrs. Some even have very hard
plastic burrs. You can tell on older coffee grinders. They jes do
NOT grind, at all! The burrs are ompletely worn out. That, or they
are merely decorative grinders and have completely useless gears.

I'd try and find out what vendors use fer Turkish coffee which is
typically ground very fine. Espresso grinders are very expensive cuz
they have hardened burrs, the purpose of which is to provide a very
uniform grind. I don't think anyone cares when it comes to Turkish
grind. I've bought it Turkish coffee pre-ground and it was as fine as
all-purpose flour (APF).

The OP also might look at grain mills.
