Threaded holes
Firstcut provides the ability to easily add threaded holes to your CNC-machined parts. We currently support UNC and UNF threads from #2 up to 1/2 in., and metric threads from M2 to M12. Because of the lack of standards between CAD packages for specifying threads, our automated systems decide where to put threads by looking for holes that could be pilot holes that are oriented suitably. Don't model internal threads; it will confuse Firstcut’s pilot hole finder. The Firstcut process uses three-axis milling, so holes can only be milled and threaded if they align with one of the three cardinal axes. More details.
