RT16.01W-2.50GMPB YBG205 Threading Insert
High-Performance Nano-PVD Solution for Precision 2.50mm Pitch External Threading
Product Overview
"Looking for a specialized external insert that delivers superior heat resistance and a clean surface finish when cutting 2.5mm pitch threads in gummy stainless steel?"
The ZCC.CT RT16.01W-2.50GMPB YBG205 is a premium external threading insert engineered for the most demanding materials. The "GM" designation features a Partial Profile geometry specifically reinforced for 2.50mm pitch threads, ensuring high edge stability and excellent thread accuracy.
Utilizing the YBG205 Grade, this insert is coated with a specialized nano-structured TiAlN PVD layer. It is the ultimate choice for machining Stainless Steel (M) and Superalloys (S), where preventing notch wear and thermal cracking is essential for maintaining production efficiency.
Key Features
- Nano-PVD YBG205 Grade: Advanced coating technology providing ultra-high heat resistance and preventing material adhesion (BUE) on the cutting edge.
- 2.50mm GM Specialized Profile: Reinforced geometry designed to handle the specific cutting pressures of 2.5mm pitches, ensuring perfect thread form.
- Superior Surface Finish: The combination of a sharp ground edge and smooth coating delivers mirror-like external threads in difficult materials.
- Extended Tool Life: High chemical stability of the YBG205 coating ensures longer intervals between tool changes compared to standard PVD grades.

Typical Applications
- External Metric (M) threads (Commonly M18 to M22 with 2.5mm pitch).
- Critical components in the Chemical, Marine, and Oil & Gas industries.
- Machining of stainless steel shafts, valve stems, and pressure fittings.
- Precision threading on high-strength aerospace fasteners.
The YBG205 Advantage
The YBG205 grade is ZCC.CT's flagship solution for difficult-to-cut materials. By combining a dense, high-hardness nano-coating with a stable carbide base, it effectively manages the extreme heat of threading stainless steel while maintaining the sharp profile needed for 2.5mm threads.
Verified User Performance
"Outstanding results on 316L stainless. No built-up edge and the tool life is nearly double what we got with previous brands."

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.
