RT16.01W-2.50GMPB YBG205 Threading Insert
High-Performance Nano-PVD Solution for Precision 2.50mm Pitch External Threading
Product Overview
"Looking for a specialized external insert that delivers superior heat resistance and a clean surface finish when cutting 2.5mm pitch threads in gummy stainless steel?"
The ZCC.CT RT16.01W-2.50GMPB YBG205 is a premium external threading insert engineered for the most demanding materials. The "GM" designation features a Partial Profile geometry specifically reinforced for 2.50mm pitch threads, ensuring high edge stability and excellent thread accuracy.
Utilizing the YBG205 Grade, this insert is coated with a specialized nano-structured TiAlN PVD layer. It is the ultimate choice for machining Stainless Steel (M) and Superalloys (S), where preventing notch wear and thermal cracking is essential for maintaining production efficiency.
Key Features
- Nano-PVD YBG205 Grade: Advanced coating technology providing ultra-high heat resistance and preventing material adhesion (BUE) on the cutting edge.
- 2.50mm GM Specialized Profile: Reinforced geometry designed to handle the specific cutting pressures of 2.5mm pitches, ensuring perfect thread form.
- Superior Surface Finish: The combination of a sharp ground edge and smooth coating delivers mirror-like external threads in difficult materials.
- Extended Tool Life: High chemical stability of the YBG205 coating ensures longer intervals between tool changes compared to standard PVD grades.

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.
