Full profile insert for highly precise internal threads

With the 16IR (60°) UN/UNC threading insert, professional users receive a specialized tool for internal thread turning of imperial Unified National threads. The full profile finishes the thread including the major diameter in a single operation. The RT315 carbide grade with its durable PVD coating creates good conditions for a long tool life and provides reliable chip control when machining various alloys.

Applications

The 16IR insert is designed for professional use in mechanical and plant engineering. It is a well-thought-out solution for cutting custom-fit UN and UNC internal threads in pipe connections, fittings, and structural components. The RT315 grade is ideally suited for operations requiring frequent changes between different steel grades and stainless materials.

Special features

Thanks to the specific full profile geometry, a clean thread finish without unwanted burr formation is achieved, effectively saving subsequent machining steps. The temperature-resistant PVD coating protects the carbide cutting edge against premature wear and supports a consistent surface quality along the entire thread profile.
