I have a 0.250" shank diameter carbide endmill that I need to make shorter for a specific application. Is there a way to safely lop it off? End condition isn't real important. I have a Makita 4.5" angle/disc grinder with those typical brown/red blades, but will that get through it? I've also seen diamond coated blades, I think they use for tile/stone but I'm not clear if the abrasive is on the edge vs. the face? Would that work?
