How hard is this part supposed to be? I know people who machine hardened steels, but they all use carbide tools for everything. I don't think that HSS has the wear resistance to deal with hard metals. You might be able to get one or two holes out of a HSS reamer (if even that) in hard stuff, but I don't think that the low cost will be an advantage this time. If it was me, I think I would splurge on the carbide reamer, it should hopefully last long enough to be used again in the coming years.
