    Dec 14 2016 · Often I will skip the roughing pass and cut 3D using only a finish pass. With an 8% stepover the side of a 1/16" bit is only removing 0.005" of material so it is possible to carve at full 1" depth. It is important to watch the preview. If the bit jumps to a new area it may plunge at full depth and break the bit.
