TaeguTec TCMT110204MT TT7015
The High-Velocity Specialist: Maximum Productivity for Steel and Cast Iron
Product Overview
"Which insert is best for high-speed continuous turning of hardened steel and abrasive cast iron?"
The TaeguTec TCMT110204MT TT7015 is a premium 11mm triangular turning insert engineered for high-velocity operations in Steel (ISO P) and Cast Iron (ISO K). Utilizing the advanced TT7015 CVD coating, this insert features a thick Al2O3 (Alumina) layer combined with a specialized MT-TiCN coating to provide extreme crater wear resistance and thermal stability. The MT (Medium Turning) chipbreaker offers a positive rake angle that balances low cutting forces with exceptional chip control, making it the ideal choice for finishing to medium-duty machining where surface quality and dimensional accuracy are paramount.
Core Advantages
The TT7015 grade is optimized for maximum surface speeds, drastically reducing cycle times in production environments.
Positive chipbreaker design facilitates smooth chip evacuation and prevents work-hardening of the workpiece surface.
Specially treated substrate prevents edge deformation and cracking even during high-heat dry machining.

"TT7015 is incredible for high-speed iron. We increased RPM by 30% without losing edge life."
— Bernd W., Germany"Perfect finish on our 4140 steel shafts. Fast shipping to Ohio."
— James D., USA"The MT chipbreaker handles thin chips flawlessly. Great for precision boring."
— Sato T., Japan"Ottima resistenza all'usura su ghisa. Molto soddisfatto."
— Giovanni M., Italy"Reliable grade for continuous production. TaeguTec quality is top-notch."
— Robert K., USAFrequently Asked Questions
A: TT7015 is a high-speed finishing grade. For heavy interruptions, a tougher grade like TT8020 or TT8125 is recommended to avoid edge chipping.
A: While it can cut stainless, the CVD coating on TT7015 is optimized for ISO P/K. For better results in stainless, use TT9080 or TT8020.
A: The 0.4mm radius (04) is ideal for achieving fine surface finishes and reducing tool pressure in thin-walled or small-diameter parts.
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.
