Precise thread production with the 16ER UN/UNC insert
This full profile threading insert is a well-thought-out solution for manufacturing dimensionally accurate UN and UNC external threads. The PVD-coated universal grade RT315 (P15-P25 / M10-M25) combines wear resistance with a stable cutting edge, creating favorable conditions for economical batch production. The full profile ensures that the thread is cut completely, including the crest, which often makes subsequent deburring unnecessary.

Applications
This indexable insert is designed for thread turning on industrial components, fasteners, and pipes requiring an American UN or UNC thread. The turning insert is suitable for both conventional lathes and CNC operations. Thanks to its broad material compatibility, it provides flexibility for workshops that frequently switch between machining steel, stainless steel, aluminum, or special alloys.
Special features
The combination of an exact 60° full profile and the tough substrate of the RT315 grade offers high process reliability. Since the insert generates the thread root and flanks in one continuous cutting profile, excellent surface finishes can be achieved. Furthermore, the PVD coating counteracts built-up edge formation when turning non-ferrous metals and protects against premature wear during stainless steel machining.
