A thread mill can perform many func-tions. Depending on the product, a mill can drill a hole, chamfer it and machine the thread. A single tool could be used in thread milling to make a wide range of hole sizes, interior and exterior threads and right-handed and left-handed threads. Thread milling also allows users to closely and consistently control pitch diameter and achieve tight tolerances. And thread milling pro-vides a good finish to a thread, which is always an issueGWSTOOLGROUP.COMwith tapping, particularly with difficult-to-machine ex-otic materials.CTEctemag.com/cteguide.com69Threading.indd 69 7/17/20 3:34 PM'
