Will this end-mill plunge?

Sorry, the 2nd time I used the word adaptor it should have read collet. You could still use the cutters with a 6mm adaptor without changing the collet. These cutters are seriously cheap and very good and I cut material up 15mm thick and could go to 18mm, but using the 3.172 cutter. G.

Would you be able to link to an adaptor? I've not seen any. I presume it is just a kind of sheath that makes the shank larger? It would be good to have.

Also, I should have said above that when I plunge the Z axis I only do so in wood and plastics.
