Internal Threading with the 16IR-T-AG60
The 16IR-T-AG60 threading insert, featuring a 60° partial profile and the high-performance RT330 universal grade, is a well-thought-out solution for reliable metric internal threading. The partial profile design opens up flexible application possibilities, allowing a single insert to be used for multiple thread pitches. Furthermore, the wear-resistant PVD coating supports efficient workflows across various workpiece materials.

Applications
This indexable insert is geared towards professional use in the machining of ISO internal threads. It is exceptionally well-suited for flexible contour machining when dealing with varying thread sizes, eliminating the need for frequent tool changes for every pitch. The RT330 grade proves its value not only when machining steel and stainless steel, but also in cast iron and non-ferrous metal applications.
Special features
A key advantage is the broad usability provided by the 60° partial profile design. The PVD coating on the cutting edge effectively reduces edge wear and creates good conditions for consistent machining results. Additionally, its design as a universal grade helps reduce the necessary tooling inventory, since a large portion of internal threading tasks can be covered with a single insert.
