They shouldn't be used in a mill or lathe as they are designed mainly for use in a hand drill, for very rough cutting. I use mine in a pneumatic drill, and only by hand holding, that allows them to vibrate as much as they want to.
Because of the layout of the cutting edges they will automatically start to chatter if you use them in a rigid machine. They are more like a file rather than a cutter.

die grinder, though i do have an upcoming project where i intended to use one in a machine. i figured they would work better in a machine since carbide likes it rigid.
i was thinking maybe i needed to finally buy a high quality die grinder with speed control and some torque. its sort of hard to justify when you use rotary files ten minutes a year but maybe id use them more if i had a good die grinder.
i was also wondering but never made any relation to using them in a climbing vs conventional sense.
