TLDR: Do I remove the plastic circle around the endmills I purchased from v1engineering?
I recently purchased a couple endmills from the v1engineering shop, namely the 45° V Bit, and the Single Flute Bit. On these endmills there is a plastic piece attached to the shank of the endmill (pictured below)
Am I supposed to remove the plastic from the shank?
I can’t remove it only with my hands and I don’t want to risk putting it in an vise or press to remove it if it is supposed to be on the endmill during use.
Please humor my ignorance if this is an obvious question.
