RT16.01W-1.75GMPB YBG205 Threading Insert
Precision 1.75mm Pitch Nano-PVD Solution for M12 External Threading in Stainless Steel
Product Overview
"Need a stable and high-heat resistant insert for M12 external threading on 316 or 304 stainless steel shafts?"
The ZCC.CT RT16.01W-1.75GMPB YBG205 is a high-performance external threading insert optimized for 1.75mm pitch applications. The "GM" designation features a Partial Profile geometry specifically reinforced to balance cutting sharpness with edge strength, ensuring consistent thread forms in difficult-to-machine materials.
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 notch wear, which are common when threading gummy Stainless Steel (M) or abrasive High-Temperature Alloys (S).
Key Features
- Advanced Nano-PVD YBG205 Grade: Engineered for extreme thermal stability and high surface hardness, providing the ultimate defense against gummy materials.
- Reinforced 1.75mm GM Profile: Geometry optimized to handle the specific cutting loads of M12 threads, ensuring high thread accuracy and minimal vibration.
- Exceptional Edge Sharpness: Ground to perfection to reduce work-hardening in stainless steel, resulting in mirror-like surface finishes.
- Chemical Stability: The dense nano-coating prevents chemical diffusion at the cutting tip, significantly extending tool life in high-temp alloys.

The Nano-PVD Edge
The YBG205 grade represents the peak of ZCC.CT's coating technology for difficult materials. By utilizing a dense nano-structured coating, it provides an ultra-smooth surface that prevents material from welding to the insert, which is vital for maintaining the strict 1.75mm pitch geometry in high-performance alloys.
Verified User Performance
"Absolutely brilliant on 316 stainless. No chipping on the tip and the threads come out incredibly clean. Perfect for M12 bolts."
— Julian W., UK"Switched from a major competitor and the tool life of YBG205 is noticeably better in high-temp alloys. Consistent pitch every time."
— Pierre L., France

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.
