TaeguTec CCMT120404MT TT5100
Premium CVD Grade for High-Speed Cast Iron Machining Stability
Product Overview
"Which insert grade is most reliable for high-speed continuous turning of grey and nodular cast iron without premature edge chipping?"
The TaeguTec CCMT120404MT TT5100 is an 80° rhombic turning insert specifically optimized for ISO K (Cast Iron) applications. Featuring the robust TT5100 CVD coating technology, this insert provides a thick alumina layer that acts as a superior thermal barrier during high-speed dry machining. The MT chipbreaker (Medium Turning) is engineered for versatile chip control across varying depths of cut, ensuring that abrasive cast iron dust is managed efficiently while maintaining edge sharpness for precision finishing and medium-duty roughing.
Key Features
Thick Al2O3 layer provides excellent crater wear resistance and thermal protection for high-speed runs.
Designed to balance cutting force and edge strength, making it suitable for a wide range of cast iron grades.
The hard substrate is specifically formulated to withstand the abrasive nature of grey and ductile iron.

Verified Global Feedback
"Fast and reliable"
Using TT5100 for brake rotors. We bumped the speed by 30% and the tool life actually increased. Very stable.
— AutoParts MFG (USA)"Exzellent für Gusseisen"
Excellent heat resistance. No crater wear even after hours of high-speed turning in grey iron.
— Gusswerk GmbH (Germany)"Molto Resistente"
A very solid medium turning tool. The MT chipbreaker handles nodular iron chips perfectly.
— Meccanica Nord (Italy)Frequently Asked Questions
1. Can I use TT5100 on Steel (ISO P)?
TT5100 is optimized for Cast Iron. For Steel machining, we recommend the TT8115 or TT8125 grades for better performance.
2. Is this grade suitable for dry machining?
Yes! The CVD thick Al2O3 layer is specifically designed to excel in dry machining environments by providing a superior thermal barrier.
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.
