RT16.01W-1.25GMPB YBG205 Threading Insert
Precision Nano-PVD Solution for 1.25mm Pitch External Threading in Difficult Materials
Product Overview
"Achieve superior thread accuracy and heat resistance on 1.25mm pitch external threads in stainless steel and titanium alloys."
The ZCC.CT RT16.01W-1.25GMPB YBG205 is a high-performance external threading insert designed for precision machining. The "GM" designation features a Partial Profile geometry reinforced for 1.25mm pitch applications, ensuring excellent edge stability and thread surface quality.
Utilizing the premium YBG205 Grade, this insert features a multi-layer nano-structured PVD coating. It is specifically engineered to excel in Stainless Steel (M) and Superalloys (S), where preventing built-up edge (BUE) and managing high cutting temperatures are critical for success.
Key Features
- Nano-PVD YBG205 Grade: Advanced coating technology providing ultra-high thermal stability and extreme hardness to handle gummy and abrasive materials.
- Reinforced 1.25mm GM Profile: Geometry optimized to reduce vibration and prevent chipping during the machining of 1.25mm external thread forms.
- Excellent Surface Integrity: Sharp ground edges combined with a smooth nano-coating deliver mirror-like threads even in work-hardening stainless steels.
- Extended Tool Longevity: High chemical stability of the YBG205 coating prevents premature wear, reducing machine downtime.

- Automotive fuel system fittings and hydraulic connections.
- High-performance threading in chemical and marine environments.
The Nano-PVD Advantage
The YBG205 grade is the pinnacle of coating technology for heat-resistant alloys. By maintaining a sharp edge and providing an ultra-low coefficient of friction, it prevents the work-hardening and "tearing" of thread roots often associated with machining 1.25mm pitches in stainless steel.
Verified User Performance
"Outstanding on M12x1.25 fine threads in 316 stainless. The finish is perfect and the tool life outlasts everything else we've tried."
— Hiroshi M., Japan"Very stable edge. The YBG205 coating really handles the heat when threading titanium alloys. Highly recommend for 1.25 pitches."
— Daniel K., Switzerland

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
