DAPRA - Make large diameter holes CRAZY fast! High-feed helixing a 4.0" hole, 2.5" deep, in 4140PH

Hole-making can be time-consuming and tool-consuming. DAPRA has long been a proponent of helixing holes, due to the quick cycle time and the flexibility of hole sizes (change program vs changing the tool). With high-feed, this process is taken to a whole new level, shortening cycle times to never before seen levels. Even on a 40-taper machine, both small and large diameter holes can be made quickly and easily, as you'll see here.
