16ERG55-TF PR1115
Kyocera Precision Tools | Advanced PVD Threading Performance
The Kyocera 16ERG55-TF PR1115 is a high-precision laydown threading insert designed for external 55° thread profiles. Featuring a partial profile design, this versatile tool covers a wide range of TPI (Threads Per Inch) requirements. The integrated TF Chipbreaker is specifically engineered to handle the difficult chip evacuation typical of stainless steel threading and low-carbon steels, ensuring a clean finish and preventing "bird-nesting" on your CNC lathe.

PR1115 MEGACOAT Technology
The PR1115 grade features Kyocera's proprietary PVD coating. It is a high-hardness, heat-resistant grade designed specifically for stainless steel machining. It provides superior resistance to built-up edge and flank wear, making it the primary choice for precision components in the medical and aerospace industries.
TF Chipbreaker Geometry
The TF molded chipbreaker is a game-changer for threading. By controlling the chip flow during each pass, it reduces cutting resistance and prevents surface damage. This geometry allows for more aggressive feed rates and fewer passes, directly increasing throughput on your production line.
