How are you using the burrs?
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.
