Stellram's thread mills complete a thread in one machine set up. Tools with NPT, NPTF, BSPT, BSW thread forms produce internal, external, right hand and left hand threads with the same tools. They produce easy to handle chips, minimize power requirements and interrupted cuts and casting mis-match is no problem. Excellent surface finish eliminates deburring operations. Multi-start threads are easy to produce and there are no broken taps to remove.
