Is it a problem because of too small collet presure ?

Edit:

Im searching forum for some info and i found this:

300 - 500 psi sounds about right,

Remember those times when would use lot less on thin walled bored parts

and of course never, never , close a collet without part in it at 300 psi,

been there done that , wrote the check for new one,

Good luck,

I did that (text in bold).

can anyone else confirm this ?

I have this collets: DIN 6364 163 E
