Machining Large-Diameter Holes? Consider Helixing with Indexable High-Feed Tooling

We see it all the time – helical interpolation with indexable high-feed tooling can be a game-changer if you’re regularly machining large-diameter holes. Here we explore your different indexable tooling options and demonstrate the quick cycle times you can expect helixing with high-feed tooling, machining a 4“ diameter hole in 2.5“ thick 4140 PH steel on a 40-taper machine. Cycle time? Just two and a half minutes. No starter hole and no step cuts required. Check out our website for more information on helixing large-diameter holes:
