High-Performance Threading Insert 16IR for Metric Internal Threads

The 16IR full profile threading insert is specifically designed for the precise machining of metric internal threads with a 60° flank angle. Configured as a right-hand version, it covers an exceptionally broad range of machining tasks in combination with the PVD-coated RT315 grade. The ready-to-use shape of the full profile produces clean thread flanks and high dimensional accuracy, typically eliminating the need for time-consuming reworking. This high-performance indexable insert is supplied in a practical packaging unit of 2 pieces.

Applications

This threading insert is excellently suited for demanding internal threading operations in modern mechanical engineering, plant construction, and toolmaking. Thanks to the broadly defined RT315 universal grade, it is an excellent choice when frequently changing materials such as steel, stainless steel, non-ferrous metals, and special alloys. It supports flexible production processes where reliability and profile accuracy are paramount.

Special features

The 60° full profile enables the creation of dimensionally accurate threads in a single continuous machining operation. The PVD coating of the RT315 cutting grade ensures high wear resistance and very good thermal stability of the cutting edge. This combination favors safe workflows and consistent thread quality, even under challenging cutting conditions.
