RT16.01N-2.50GMPB YBG202 Threading Insert
Robust 2.50mm Pitch Internal Threading Solution for Steel and Stainless Steel
Product Overview
"Need a reliable internal insert that manages chip flow and vibration on 2.50mm pitch metric threads in stainless or alloy steel?"
The ZCC.CT RT16.01N-2.50GMPB YBG202 is a professional-grade internal threading insert designed for deep-hole threading and heavy cutting loads. The "GM" designation identifies its Partial Profile geometry, specifically reinforced to handle 2.50mm pitch threads while maintaining excellent chip control inside the bore.
Equipped with the YBG202 Grade, this insert features a multi-layer nc-TiAlN PVD coating. It is the premier "all-rounder" for Steel (P) and Stainless Steel (M), offering the high impact toughness required to survive the restricted chip evacuation space of internal machining.
Key Features
- Internal-Optimized YBG202 Grade: Provides exceptional edge toughness to handle the increased vibration and heat common in internal threading operations.
- Reinforced 2.50mm GM Profile: Geometry specifically ground to manage the heavy material removal of larger pitches like M18-M22, ensuring clean thread roots.
- Broad Application Range: Seamlessly transitions between Stainless Steel (M) and general Steels (P), reducing the need for constant tool changes.
- Advanced nc-TiAlN Coating: Offers high thermal stability and a low coefficient of friction, critical for preventing "chip welding" inside the workpiece.

Typical Applications
- Large-diameter internal threads for industrial nut and coupling production.
- Standard M18, M20, and M22 threads in alloy steel blocks.
- Hydraulic cylinder end caps and heavy machinery internal fittings.
- Excellent for both blind-hole and through-hole internal threading.
The Internal Advantage
The YBG202 grade provides the structural stability needed when the insert is hidden deep inside a part. For larger 2.50mm pitches, managing the chip volume is vital; the GM profile ensures that chips are broken effectively, preventing the "nesting" that often leads to insert failure in internal bores.
Verified User Performance
"Very stable inside the bore. We use these for M20 internal threads in stainless steel and the tool life is impressive. Clean chips and no vibration."
— Stefan L., Austria"The 2.50GM profile is tough. It handles the larger depth of cut perfectly on our heavy CNC lathes. Best value for internal threading."
— Marek T., Poland

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.
