RT16.01W-1.25GMPB YBG202 Threading Insert
Versatile 1.25mm Pitch External Threading Solution for Steel and Stainless Steel
Product Overview
"Need a dependable external insert that delivers precise 1.25mm threads across carbon steel and stainless alloys with consistent tool life?"
The ZCC.CT RT16.01W-1.25GMPB YBG202 is a professional-grade external threading insert built for high-efficiency production environments. The "GM" designation identifies its Partial Profile geometry, reinforced to handle 1.25mm pitch threading with optimized chip control 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 versatility, offering a superb balance of substrate toughness and coating hardness for Steel (P) and Stainless Steel (M) machining.
Key Features
- Balanced YBG202 PVD Grade: Provides the necessary toughness to resist micro-chipping while maintaining excellent wear resistance in alloy steels.
- Precision 1.25mm GM Profile: Geometry optimized to reduce vibration and cutting forces, ensuring precise 1.25mm thread forms and sharp roots.
- Universal Workshop Solution: A single insert for Steel, Stainless Steel, and Cast Iron, streamlining inventory and reducing operational costs.
- Enhanced nc-TiAlN Coating: Offers high thermal stability and a smooth surface, resulting in cleaner external thread finishes.

The YBG202 Advantage
The YBG202 grade is the quintessential "workhorse" grade. It provides the toughness required to handle variable conditions in general machine shops while the PVD coating ensures the edge remains sharp during long runs in carbon steels. For 1.25mm external pitches, it is the most dependable choice for balancing tool life and cost.
Verified User Performance
"Consistent results on every batch. We use YBG202 for our 1.25 pitch threads in alloy steel and the finish is always top-notch."
— Robert K., UK"The best value for M10x1.25 threading. Switched to ZCC and the life of the YBG202 is equal to much more expensive 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.
