RT22.01N-4.00GMPB YBG201 Threading Insert
Robust Internal Solution for Large 4.00mm Pitch Metric & UN Threading Applications
Product Overview
"Need a stable, heavy-duty insert for cutting 4.0mm internal threads in high-tensile steels and stainless components?"
The ZCC.CT RT22.01N-4.00GMPB YBG201 is a high-strength internal threading insert designed on the Size 22 (1/2" I.C.) platform. The "GM" designation represents its specialized Partial Profile geometry optimized for large-pitch threads (up to 4.0mm), offering superior rigidity and edge toughness compared to standard size 16 inserts.
Equipped with the YBG202 Grade, this insert features a multi-layer nc-TiAlN PVD coating. It is specifically engineered to handle the intense heat and mechanical stress generated during large-pitch internal boring operations, making it ideal for Carbon Steels (P) and Stainless Steels (M).
Key Features
- Reinforced 22 Size Platform: Provides maximum stability and vibration dampening for large internal diameters, ensuring superior thread surface finish.
- Large Pitch Geometry: Specifically engineered for 4.0mm threads, providing optimal clearance and cutting-edge strength for heavy-duty applications.
- YBG201 Advanced PVD Coating: Multi-layer nc-TiAlN coating provides a thermal barrier, extending tool life in abrasive steels and gummy stainless alloys.
- Precision Ground Profile: Ensures accurate thread form and repeatability, reducing the need for constant offsets during production runs.

Typical Applications
- Large internal Metric (M) and Unified (UN) threads with 4.0mm pitch.
- Machining of heavy-duty couplings, pipe fittings, and flanges.
- Aerospace and Energy sector components requiring large diameter boring.
- Production threading in stainless 304, 316, and high-alloy steels.
The YBG201 Performance
The YBG201 grade is ZCC.CT's workhorse for size 22 threading inserts. Large-pitch machining generates significant pressure; YBG201 provides the substrate toughness to prevent fracturing while the coating ensures the edge remains sharp and productive over long cycles.
Verified User Performance
"Outstanding stability for internal 4mm pitch work. The size 22 insert is much more reliable than trying to push a size 16 to its limits."
— Hans G., Germany"Clean threads in stainless steel components. YBG201 grade maintains a great edge even in deep boring applications."
— Robert M., UK

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.
