Shell reamer disassembly

[AGCB97]

What is the proper way to remove a shell reamer from its arbor? The long taper makes it very tight and I don't want to ruin either part.
Thanks

Hold the part of the shank that drives the reamer (sometimes has flats on it) loosely in a vise and drive against the shank at the cutting end of the reamer with a drift. If one has a press, that is an even better method. Some reamer shanks have a screw and nut arrangement incorporated in the driver to force the reamer off the taper.

Thanks
Maybe I'll try using a bearing splitter and the press

Yes, a bearing splitter is helpful sometimes, especially when the mandrel has no flats on it.

The vise and a snug fitting open end wrench worked well on the #6 but the #7 needed the press. Then a-piece-a-cake. Thanks
