WEBAug 31, 2022 · Ball mill cutters are ideal for 3dimensional milling operations. Woodruff cutters have teeth perpendicular to the outside diameter and are used to cut keyways into shafts and other parts. Thread mill cutters produce threaded holes, although taps can do that faster. Fly cutters are singlepoint cutting tools that work much like a face mill.
