Reliable thread turning for Whitworth standards
The 16IR threading insert in right-hand execution is a specialized solution for turning Whitworth standard internal threads. As a full-profile insert, it cuts the thread with a precise 55° flank angle and simultaneously profiles the crest, promoting accurate thread geometry without the need for additional deburring. The robust RT315 carbide grade features a durable PVD coating, establishing excellent conditions for consistent use in both batch and single-part production.

Applications
This insert has been specifically designed for turning internal threads in unalloyed and alloyed steels, as well as stainless steel materials. With its standardized full profile, the tool covers typical assembly and construction threads complying with the Whitworth standard. The insert performs reliably at cutting speeds ranging from 60 to 90 m/min, making it a flexible choice for both conventional lathes and modern CNC machining environments.
Special features
A major benefit of this full-profile threading tool is its ability to completely form the thread, ensuring the exact 55° flank angle while cleanly finishing the crest. The universally applicable PVD coating of the RT315 grade minimizes built-up edge formation and contributes to consistent cutting performance. The availability of multiple pitches, ranging from 8 to 18 threads per inch, opens up a wide range of applications for various thread dimensions.
