A dual tip cutter () includes a body () defining a feed direction (F), a cutting direction (C) perpendicular to the feed direction, and a depth direction (D) perpendicular to both feed and cutting directions. A first cutting portion () is fixed relative to the body at a body first end. A second cutting portion () is fixed relative to the body at the body first end, adjacent the first cutting portion. The first and second cutting portions are stacked in the cutting direction so that the first cutting portion forms a leading cutting portion and the second cutting portion forms a trailing cutting portion for simultaneous cutting. The second cutting portion extends from the body further in the depth direction than the first cutting portion. A relative position between the first and second cutting portions is set such that a total chip load is shared between the first and second cutting portions in a predetermined ratio (K).
