The limitations of using milling tools to prepare holes for finishing become apparent as hole depth and volume increase. Enter the relatively simple and affordable twin cutter, which can solve this and virtually any other holemaking problem.
Anyone who’s made holes understands the difficulties that can arise: vibration, wander and even breakage. When it comes to production-level volume, these issues become even more limiting. Many turn to helical interpolation with a mill as a reliable way to rough out holes. We’re here to tell you there’s a faster, easier option.
