TaeguTec CNMG190612 TT5100
The Cast Iron Powerhouse: High-Speed Stability for Heavy-Duty Machining
Product Overview
"Which carbide insert is best for high-speed turning of Gray and Ductile Cast Iron where wear resistance and edge stability are the top priorities?"
The TaeguTec CNMG190612 TT5100 is a formidable 80° rhombic insert engineered specifically for ISO K (Cast Iron) applications. Featuring the specialized TT5100 CVD grade, it utilizes a thick Al2O3 coating combined with a highly wear-resistant substrate to withstand the abrasive nature of cast iron at high cutting speeds. The 19mm edge length and 1.2mm corner radius provide the structural integrity required for heavy roughing and semi-finishing, ensuring maximum metal removal rates (MRR) without compromising tool life.
Key Features
Specialized TT5100 substrate is designed to resist the abrasive wear typical of gray cast iron machining.
The 1906 size profile provides the mass and stability needed for large-scale industrial components and high depths of cut.
Thick CVD coating allows for significantly higher cutting speeds compared to conventional grades.

Verified Global Feedback
"Gray Iron Specialist"
We use TT5100 for our pump housing line. It easily outlasts our previous grade by 30% at 400m/min.
— Castings Ltd. (Germany)"Maximum Stability"
The 1906 size is essential for our heavy roughing. Very stable edge and predictable tool life.
— Heavy Machining Corp. (USA)"Solid Performance"
Great for ductile iron turning. Good chip control even at high feed rates.
— Precision Works (Italy)Frequently Asked Questions
1. Can this be used for Steel (ISO P)?
TT5100 is specifically for Cast Iron. For Steel, please refer to our TT8125 or TT8115 grade listings.
2. What is the benefit of the 1.2mm radius?
The 1.2mm radius offers significant edge strength for heavy cuts and allows for higher feed rates while maintaining a decent surface finish.
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.
