This should be done, or at least finished, on a cylindrical grinder IMO.

Anyone ever cut down a reamer shaft? I've got a 1" reamer that I need to be
able to hold in a half inch chuck to ream polyethlylene. Tailstock is M2 and
the reamer was not availiable in anything less than M3. By the time I added a
M3 to M2 to a M3 reamer, it would be too long. Shaft is not real hard, file
will cut the surface. Ideas?
