advised to opt for the end mill holders??

End mill holders are designed to hold end mills. Collets are workholding
devices. That said, you can use a collet to hold an end mill. The problem
is that there's no way to lock the end mill in the collet to prevent it from
sucking out while cutting. That could ruin a work piece in which you'd
invested a lot of time. You can probably get away with it indefinitely on
a small machine taking light cuts, but it is something to consider.
