RT16.01N-G60P YBG201 Threading Insert
Universal 60° Internal Threading Solution for Metric and UN Thread Profiles
Product Overview
"Which internal threading insert offers the most versatility for cutting various 60° pitches in both steel and stainless steel without sacrificing tool life?"
The ZCC.CT RT16.01N-G60P YBG201 is a high-precision internal threading insert designed with a 60° Partial Profile (G60). This versatile geometry allows a single insert to cut a wide range of thread pitches for both Metric (ISO) and Unified (UN) standards.
Powered by the YBG201 Grade, it features a specialized PVD coating over a balanced carbide substrate. This combination provides excellent thermal stability and impact resistance, making it the ideal "general-purpose" choice for internal boring applications across Steel (P) and Stainless Steel (M) workpieces.
Key Features
- YBG201 General-Purpose Grade: A resilient PVD coating that excels in preventing adhesive wear, making it reliable for shops handling diverse materials.
- Partial Profile Versatility: The G60 design allows you to machine multiple pitches (within the size 16 range) with a single tool, reducing inventory costs.
- Internal Geometry Optimization: Specifically ground for internal threading to ensure efficient chip evacuation in confined boring holes.
- Excellent Edge Toughness: Resists micro-chipping even during light interrupted cuts or when machining high-tensile alloy steels.

Typical Applications
- Internal Metric (M) and Unified (UNC/UNF) threads.
- Boring and threading of machine components and couplings.
- Suitable for Carbon Steel, Alloy Steel, and Stainless Steel.
- Optimized for internal threading where chip control is critical.
Performance Note
The G60 Partial Profile is the ultimate shop-saver. It eliminates the need for pitch-specific inserts for general threading tasks. However, for high-volume production requiring exact crest truncation, we recommend ZCC.CT's full-profile series.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
