RT16.01W-11WPB YBG205 Threading Insert
Premium PVD Solution for 11 TPI Whitworth 55° Threading in Stainless Steel
Product Overview
"Which threading insert delivers the sharpest edge and highest heat resistance for 11 TPI Whitworth threads on stainless steel pipe fittings and alloy shafts?"
The ZCC.CT RT16.01W-11WPB YBG205 is a high-performance external threading insert engineered for the Whitworth 55° (W) standard. Featuring the advanced YBG205 Grade, it combines a high-toughness carbide substrate with a specialized nano-TiAlN PVD coating.
Optimized for 11 Threads Per Inch (TPI), this partial profile (PB) insert is the definitive choice for machining stainless steel (M) and high-temperature alloys. The YBG205 grade is specifically designed to resist built-up edge (BUE), ensuring a precision thread surface even in adhesive materials.
Key Features
- YBG205 Nano-PVD Grade: Outperforms standard PVD coatings in heat resistance and hardness, specifically tailored for the sticky nature of stainless steel.
- High Edge Sharpness: The ground cutting geometry reduces radial forces and prevents work hardening of the workpiece surface.
- Anti-Chipping Technology: Advanced substrate toughness ensures reliable performance in light interrupted cuts or varying thread depths.
- Precision 55° Geometry: Fully ground profile ensures strict adherence to BSW/Whitworth thread standards for gas, water, and steam fittings.

YBG205 Advantage
The YBG205 grade is ZCC.CT's top-tier solution for difficult-to-cut materials. By combining high thermal stability with a very sharp cutting edge, it excels where standard grades fail—especially in precision threading of austenitic stainless steels like 304 and 316.
Verified User Performance
"Absolutely perfect for our 316 stainless valve bodies. The YBG205 grade eliminated edge chipping issues."
— Giovanni B., Italy"Excellent 11 TPI thread finish. Consistent life across 100+ alloy steel parts. Highly recommended."

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.
