Does anyone know this kind of collet?
It has 10 ° angle,( 20 ° taper)
The ER collets are 8° ( 16° taper)

Look up TG type collets, TG100 most common, also TG75 and TG150
 
I just want to know if these collets exist
Because i have a spindle with a 20° taper and i need collets for the spindle

Sounds like your spindle is set up for using a Warner Swasey turret lathe style collet. See the next thread for a a couple of examples. I think you need to look at your spindle bore a little closer behind the angle. We NEED some dimensions of your spindle so a collet can be found. Again, the samples in the other thread is the configuration you need to look for in your spindle. The thru bore of your spindle will probably be the same size as the tail end of the collet you are looking for.

I think the spindle is from a internal grinder, no spindle bore
The collets are not for myself, but for a friend
The taper is 20° (10° angle), biggest diameter is about 24 mm

Now we are getting more information. That helps. Thank you kindly.
 
It's an old round belt driven internal grinding spindle
Made by GMN R50680
I've modified the inner taper to a taper for ER25 collets
