I'm looking around at what is available in cutting tools for threading operations on a lathe, and would like any experience-based or expert opinions on how best to outfit a 12" 5900-series Clausing lathe for internal and external threading. My needs might include a range of threads from 40-16 TPI for instrumentation applications and general purpose usage. I have seen information that says laydown type inserts are the best if you go to insert technology, but I am concerned that they may be limited for smaller ID threading work. I have very limited experience in single point threading, so I'm open to any considerations.
