I have an SDS roto-hammer, and I use Bosh core drill bits. These bits have three separate parts: the core, the arbor, and the pilot.
I often have trouble removing the core from the arbor. Are you supposed to oil it before you assemble it? Is there a trick to taking the bits apart?

use never sieze and do you have SDS plus or max???

Ordinary SDS plus. Might try anti-seize. The arbor has extremely coarse, well rounded threads. Usually, I have to keep hitting / dropping the thing until, like a bad baseball bat, the 'ring' changes to a 'duhnk.' Then the pieces separate easily.

okay it's threaded...
more than likely you have burrs on the shank / cutter mating surfaces...
I use never size and pipe wrenches to dissasemle.....

No burrs. I think drilling dust is getting in. Maybe. Can't grab either piece with tools; the metal is harder than the tools :(
dust can very easily be yur culpret..
