High-performance 16IR-T-AG55 partial profile insert
The PVD-coated 16IR-T-AG55 threading insert in the universal grade RT315 is designed for reliable internal threading. With its 55° flank angle, it accurately matches standard imperial threads, such as those found in the Whitworth or BSP systems. The partial profile offers a significant practical benefit: instead of requiring a different insert for every thread pitch, this tool covers the range from 48 to 8 threads per inch. This reduces setup times, lowers tooling costs, and opens up flexible applications in modern machining.

Applications
This imperial internal threading insert is a well-thought-out solution for demanding turning tasks. It is predominantly used when Whitworth or similar 55° profiles need to be manufactured accurately. Thanks to the partial profile geometry and the universal RT315 grade, frequently changing thread pitches can be machined in alloyed and unalloyed steel, as well as stainless steel, without constantly swapping the insert.
Special features
The insert convinces with its highly wear-resistant PVD coating, which ensures good thermal stability during the cutting process. It creates excellent conditions for clean flanks and supports a high surface finish in the thread profile. The right-hand execution and the universally applicable insert size 16 ensure that it can be smoothly integrated into common internal threading tool holders.
