RT16.01W-14WPB YBG202 Threading Insert
Precision Whitworth 55° Threading Solution for Steel & Stainless Steel
Product Overview
"Which threading insert provides the best balance of edge sharpness and wear resistance for 14 TPI Whitworth external threads on alloy steel and stainless parts?"
The ZCC.CT RT16.01W-14WPB YBG202 is a high-precision external threading insert designed for the Whitworth 55° (W) standard. Featuring the YBG202 Grade, this insert utilizes a specialized nc-TiAlN PVD coating on a fine-grained carbide substrate.
Specifically engineered for 14 Threads Per Inch (TPI), the partial profile (PB) design ensures stable cutting and excellent thread finish. The YBG202 grade is a "universal" PVD choice, offering superior performance in steel (P) and stainless steel (M) applications where edge integrity is critical.
Key Features
- YBG202 PVD Grade: Features a nano-structured nc-TiAlN coating for high thermal stability and hardness, outperforming standard coatings in medium-speed applications.
- Precision Ground Profile: The 55° Whitworth geometry is precision ground to ensure exact thread forms and minimize the need for secondary finishing.
- Optimized for Steel & Stainless: The combination of a tough substrate and smooth coating reduces built-up edge (BUE) when machining adhesive materials like 304/316 stainless.
- Partial Profile Flexibility: The PB geometry allows for versatility across slightly varying thread depths while maintaining core strength.

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.
