RT16.01W-11WPB YBG205 Threading Insert
Premium PVD Solution for 11 TPI Whitworth 55° Threading in Stainless Steel
Product Overview
"Which threading insert delivers the sharpest edge and highest heat resistance for 11 TPI Whitworth threads on stainless steel pipe fittings and alloy shafts?"
The ZCC.CT RT16.01W-11WPB YBG205 is a high-performance external threading insert engineered for the Whitworth 55° (W) standard. Featuring the advanced YBG205 Grade, it combines a high-toughness carbide substrate with a specialized nano-TiAlN PVD coating.
Optimized for 11 Threads Per Inch (TPI), this partial profile (PB) insert is the definitive choice for machining stainless steel (M) and high-temperature alloys. The YBG205 grade is specifically designed to resist built-up edge (BUE), ensuring a precision thread surface even in adhesive materials.
Key Features
- YBG205 Nano-PVD Grade: Outperforms standard PVD coatings in heat resistance and hardness, specifically tailored for the sticky nature of stainless steel.
- High Edge Sharpness: The ground cutting geometry reduces radial forces and prevents work hardening of the workpiece surface.
- Anti-Chipping Technology: Advanced substrate toughness ensures reliable performance in light interrupted cuts or varying thread depths.
- Precision 55° Geometry: Fully ground profile ensures strict adherence to BSW/Whitworth thread standards for gas, water, and steam fittings.

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.
