As for the disk being hard, I would expect so, but have no way to prove it. Considering its job & how well they hold up, tho, I expect them to be plenty hard, Drilled disks are probably drilled, then treated.
Re: Harmonics, Im gonna say Naaah.. Every spacing has a speed that would create a "harmonic" if it was a possible problem,
If I was wanting to do it, Id get a good 1/8th bit & just go to a spot as close to the axle as possible & just see how hard it is, dont go thru, just see if it will drill at all. It wont unbalance it. I have a steel ruler from a machine shop supply house I was gonna hang on the wall. I grabbed a decent bit & proceeded to put a tiny dot on the ruler. No way was it gonna drill thru. Ive had that ruler 30 years, looks like the day I got it, well,, it does have a little dent,,
