RT16.01W-2.50GMPB YBG202 Threading Insert
Versatile 2.50mm Pitch External Threading Solution for Steel and Stainless Steel
Product Overview
"Seeking a reliable external insert that provides stable tool life and precision for 2.5mm pitch threads in both carbon steel and stainless alloys?"
The ZCC.CT RT16.01W-2.50GMPB YBG202 is a professional-grade external threading insert built for consistency. The "GM" designation identifies its Partial Profile geometry, which is reinforced to handle 2.50mm pitch threading with optimized cutting forces and high edge stability.
Equipped with the YBG202 Grade, this insert features a multi-layer nc-TiAlN PVD coating. This grade is renowned for its balance of hardness and toughness, making it the perfect choice for shops machining a variety of Steel (P) and Stainless Steel (M) components.
Key Features
- Balanced YBG202 PVD Grade: Provides the necessary toughness to handle interrupted cuts while maintaining a wear-resistant surface for longer tool life.
- Reinforced 2.50mm GM Profile: Geometry optimized to reduce vibration and deflection, ensuring precise thread forms on 2.5mm pitches.
- Universal Material Coverage: One insert for both steel and stainless steel applications, simplifying inventory for general machine shops.
- Smooth Thread Finish: Advanced PVD coating reduces friction and heat buildup, resulting in a superior external surface finish.

Typical Applications
- Precision external threads on Steel and Stainless Steel fasteners.
- Ideal for M18, M20, and M22 Metric threads (2.5mm pitch).
- Used widely in automotive, general machinery, and job shops.
- Reliable performance on CNC turning centers and automated lathes.
The YBG202 Performance
The YBG202 grade is the quintessential "workhorse" grade. It provides enough toughness to prevent the micro-chipping often seen in stainless steel machining, while the PVD coating ensures that the edge remains sharp during long runs in carbon and alloy steels.
Verified User Performance
"Excellent all-around insert. We use the YBG202 for most of our steel and stainless external threads. It's predictable and consistent."
— Peter H., UK"The 2.50GM profile gives a really clean finish on stainless shafts. Very impressed with the tool life for the price."

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.
