RT16.01W-11.5NPT YBG201 Threading Insert
Precision 11.5 TPI NPT Tapered Pipe Threading Solution for Multi-Material Applications
Product Overview
"Which threading insert is most reliable for leak-proof 11.5 TPI NPT tapered threads on hydraulic fittings and pressure vessels made of steel or stainless?"
The ZCC.CT RT16.01W-11.5NPT YBG201 is a specialized external threading insert designed for NPT (National Pipe Taper) 60° standards. Featuring the YBG201 Grade, this insert uses a multi-layered PVD coating that provides a high-toughness substrate for stable machining.
Engineered specifically for 11.5 Threads Per Inch (TPI), its partial profile (PB) ensures the necessary clearance and precision for tapered sealing threads. The YBG201 grade is the "versatile workhorse," offering excellent wear resistance and thermal stability across a wide range of ISO P (Steel) and ISO M (Stainless Steel) materials.
Key Features
- YBG201 Universal Grade: A perfect balance of hard coating and tough carbide, ideal for small to medium batch production where material types vary.
- Accurate 60° NPT Profile: Precision ground to meet strict ANSI/ASME B1.20.1 standards for tapered pipe threads, ensuring perfect metal-to-metal sealing.
- PVD Multi-Layer Coating: Specialized PVD process reduces friction and heat build-up, significantly extending tool life in alloy steels.
- Edge Stability: Designed to maintain edge sharpness even under the unique radial pressures of tapered threading cycles.

- Fire protection system piping and plumbing adapters.
- Machining Carbon Steel, Low-Alloy Steel, and 300-series Stainless.
Grade Advantage
The YBG201 grade is designed for general-purpose machining with a focus on edge stability. If you frequently switch between steel and stainless steel workpieces, YBG201 offers the most cost-effective and reliable tool life per insert.
Verified User Performance
"Perfect for our 1-inch NPT hydraulic connectors. The YBG201 handles the taper perfectly without vibration."
— David L., Canada"Excellent dimensional accuracy. We passed all thread gauge tests on 4140 steel shafts."

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.
