My OnFinity JourneyMan Z Axis Drill Bits Goes Deeper that Fustin 360 Depth Setting for Bore Hole. The Bore Hole is 3.9 , the Workstock is 12mm, yet the Drill Bit almost triples the Depth of Cut on the Z axis.
Note , my Router and Drill Bit are New and are inserted very tight, the Bit does not shift positions.
