Don’t try to fit the cutter to the collet before fitting the collet to the holder! Many have tried and failed.. If they ‘manage’ it the run-out will be horrible, along with the proper clamping required.
Unless the nut is a bearing type, it likely needs towards a hundred Newton-metres torque. Do not tighten too loosely and risk the cutter slipping, or the collets will be toast for proper precision.
Yeah sorry I should have said that , the nut that wont let you have a tool in the collet is a much "stiffer" fit in general , the other one has a slightly looser tolerance feel but both seem to snug up to a similar run out level.It’s not the chuck - it is the nut which should be a tighter fit, although the collet fitted with minimum-sized cutter might go in, I suppose. Do bear in mind that the collets are only as per spec for the nominal largest size of cutter shank. Swap the nuts over and it will be the other way round.
I have two chucks but about five nuts for my ER32 size. Only two nuts for my ER16. They help to speed up cutter changes at times.
I didn't realise this and thought it was just a ****ty manufacturing error with the clarke Cmd10 mill I got so removed it on the lathe before realising
