RT16.01W-1.25GMPB YBG205 Threading Insert
Precision Nano-PVD Solution for 1.25mm Pitch External Threading in Difficult Materials
Product Overview
"Achieve superior thread accuracy and heat resistance on 1.25mm pitch external threads in stainless steel and titanium alloys."
The ZCC.CT RT16.01W-1.25GMPB YBG205 is a high-performance external threading insert designed for precision machining. The "GM" designation features a Partial Profile geometry reinforced for 1.25mm pitch applications, ensuring excellent edge stability and thread surface quality.
Utilizing the premium YBG205 Grade, this insert features a multi-layer nano-structured PVD coating. It is specifically engineered to excel in Stainless Steel (M) and Superalloys (S), where preventing built-up edge (BUE) and managing high cutting temperatures are critical for success.
Key Features
- Nano-PVD YBG205 Grade: Advanced coating technology providing ultra-high thermal stability and extreme hardness to handle gummy and abrasive materials.
- Reinforced 1.25mm GM Profile: Geometry optimized to reduce vibration and prevent chipping during the machining of 1.25mm external thread forms.
- Excellent Surface Integrity: Sharp ground edges combined with a smooth nano-coating deliver mirror-like threads even in work-hardening stainless steels.
- Extended Tool Longevity: High chemical stability of the YBG205 coating prevents premature wear, reducing machine downtime.

- High-performance threading in chemical and marine environments.
The Nano-PVD Advantage
The YBG205 grade is the pinnacle of coating technology for heat-resistant alloys. By maintaining a sharp edge and providing an ultra-low coefficient of friction, it prevents the work-hardening and "tearing" of thread roots often associated with machining 1.25mm pitches in stainless steel.
Verified User Performance
"Outstanding on M12x1.25 fine threads in 316 stainless. The finish is perfect and the tool life outlasts everything else we've tried."
— Hiroshi M., Japan"Very stable edge. The YBG205 coating really handles the heat when threading titanium alloys. Highly recommend for 1.25 pitches."
— Daniel K., Switzerland
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.
