I have hardened (60HRc) bars which need to be ground between centers.

They have holes at their ends but these holes are 90 deg. with normal pilot hole drilled deeper so there is no risk of center tip hitting a bottom..

Can these be ground between normal 60 deg. centers on cylindrical grinder?

I need to make slight 2 deg taper on these bars and I wonder if shop with a grinder will fret about these "wrong" holes or not?

Talk to the grinder they may have different centers or have the equipment to re cutthe center.
