16ERAG60-TF PR1115
Kyocera Precision Tools | The Ultimate Stainless Steel Threading Solution
The Kyocera 16ERAG60-TF PR1115 is a high-performance laydown threading insert designed for external 60° thread profiles. Featuring an AG partial profile, this single insert covers an extensive range of thread pitches, making it an essential versatile tool for CNC lathe operators. The PR1115 PVD grade combined with the TF chipbreaker is specifically engineered to overcome the challenges of stainless steel threading, offering superior edge sharpness and excellent chip evacuation.

PR1115 PVD Coating
Kyocera's PR1115 grade is a high-performance PVD coated carbide substrate optimized for precision machining. It provides exceptional wear resistance and heat stability, ensuring the cutting edge remains sharp even when threading tough 300-series stainless steel or heat-resistant alloys. It effectively prevents built-up edge (BUE), a common failure in threading operations.
TF Chipbreaker Function
The TF chipbreaker is specifically designed to manage the unique chip load of threading. By forcing the chip to curl and break quickly, it reduces cutting resistance and prevents long, stringy chips from scratching the thread surface or damaging the tool. This leads to a superior surface finish and predictable tool life.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
