I'm using center drills to countersink brass. It chatters pretty bad. Is that because I have drilled a pilot hole, or is it because of the rake of the center drill? I've ordered some diamond files to change the rake of my set of drill bits as I've been having issues with chattering, especially when I move to larger bits like 1/4". Are there countersinks like burrs rather than drills that I should be using?
