RT16.01N-AG55PB YBG205 Threading Insert
High-Performance Nano-PVD Solution for 55° Internal Whitworth & Pipe Threads
Product Overview
"How can I achieve stable tool life and clean surface finishes when cutting 55° internal pipe threads in gummy stainless steel or heat-resistant alloys?"
The ZCC.CT RT16.01N-AG55PB YBG205 is a premium internal threading insert featuring a 55° Partial Profile (AG55). The "AG" designation indicates an extended pitch range, allowing one insert to handle various 55-degree Whitworth (BSW) and British Standard Pipe (BSPP/G) thread sizes.
Engineered with the YBG205 Grade, this insert features an advanced nano-structured TiAlN PVD coating. It is specifically designed for Stainless Steel (M) and Superalloys (S), where superior heat resistance and edge sharpness are required to prevent built-up edge (BUE) and thermal cracking.
Key Features
- YBG205 Nano-PVD Coating: Offers exceptional hardness and thermal stability, making it the industry standard for machining tough stainless steel (304, 316, Duplex).
- Wide Range AG55 Profile: Versatile enough to cut multiple 55° Whitworth pitches with a single insert, optimizing tool management and cost-per-part.
- Internal Geometry Optimization: Designed for internal boring bars to ensure stable cutting and efficient chip evacuation in tight internal diameters.
- Superior Edge Toughness: Resists micro-chipping even under the heat-intensive conditions of machining high-alloy steels and superalloys.

The YBG205 Advantage
The YBG205 grade is ZCC.CT's ultimate solution for high-temperature and gummy materials. Its nano-structured coating creates a thermal barrier that protects the substrate, significantly extending tool life compared to standard PVD grades when machining 300-series stainless steel.
Verified User Performance
"The YBG205 grade is a game changer for our 316 stainless pipe fittings. No more edge build-up or messy threads."
— Derek S., UK"Very versatile insert. The AG55 profile covers all our British standard internal work with perfect accuracy."
— Alan J., Australia

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.
