RT16.01N-1.75GMPB YBG205 Threading Insert
Precision 1.75mm Pitch Nano-PVD Solution for M12 Internal Threading in Stainless Steel
Product Overview
"Struggling with chip control or heat buildup while threading M12 internal holes in 316 stainless steel?"
The ZCC.CT RT16.01N-1.75GMPB YBG205 is a high-performance internal threading insert designed for demanding bores. The "GM" designation features a Partial Profile geometry reinforced to manage the specific chip loads of 1.75mm pitches, ensuring clean threads and reduced vibration inside the workpiece.
Utilizing the premium YBG205 Grade, this insert is protected by a multi-layered nc-TiAlN nano-coating. This makes it exceptionally resistant to built-up edge (BUE) and thermal cracking, which are common challenges when threading Stainless Steel (M) or High-Temperature Alloys (S) in restricted internal spaces.
Key Features
- Advanced Nano-PVD YBG205 Grade: Engineered for extreme thermal stability and high surface hardness, providing the ultimate defense against gummy materials in deep bores.
- Reinforced 1.75mm GM Profile: Geometry optimized to handle internal cutting loads of M12 threads, ensuring high thread accuracy and minimal chatter.
- Smooth Chip Evacuation: Ground to perfection to facilitate easier chip flow out of the hole, reducing the risk of chip jamming and tool breakage.
- Chemical Stability: The dense nano-coating prevents chemical diffusion at the cutting tip, significantly extending tool life in abrasive stainless steels.

Key Applications
- Internal Metric (M12) coarse threads on stainless steel couplings.
- Boring and threading of aerospace-grade titanium engine components.
- Deep hole threading in food processing and chemical pump housings.
- High-precision internal threading for industrial valves and manifolds.
The Nano-PVD Edge
The YBG205 grade represents the peak of ZCC.CT's coating technology for internal operations. By utilizing a dense nano-structured coating, it provides an ultra-smooth surface that prevents material from welding to the insert tip—a vital feature for maintaining the strict 1.75mm pitch geometry when coolant access is limited inside a bore.
Verified User Performance
"Outstanding performance in 304 stainless bores. The threads are perfect and the tool life is nearly double that of general grades."
— Thomas K., Germany"Very stable edge. Switched to YBG205 for all our M12 internal work in inconel. Highly reliable."
— David H., USA
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.
