TaeguTec TCMT110204MT TT8115
The High-Speed Finishing Specialist: Maximum Wear Resistance for Stable Steel Turning
Product Overview
"Push your cycle times to the limit with the TT8115—the hardest PVD grade in the 8100 series for maximum tool life at high surface footages."
The TaeguTec TCMT110204MT TT8115 is an 11mm triangular turning insert optimized for high-productivity Steel (ISO P) applications. While many PVD grades focus on toughness, the TT8115 grade is specifically engineered for wear resistance and high-speed stability. It is the ideal choice for continuous cuts where dimensional accuracy over long runs is paramount. The MT (Medium Turning) chipbreaker provides a versatile geometry that reduces cutting forces while maintaining excellent chip evacuation, while the 0.4mm corner radius ensures a high-quality surface finish on the workpiece.
Core Advantages
A specialized PVD coating with ultra-high hardness that resists abrasive wear better than standard grades in carbon and alloy steels.
Engineered to maintain a sharp cutting edge at elevated temperatures, allowing for increased Vc (cutting speed) and reduced cycle times.
The MT chipbreaker's land design provides stable chip breaking in finishing to medium turning, even in "gummy" low-carbon steels.

Compatible Tooling Systems
This insert is precision-matched for TCMT 11 size tool holders, boring bars, and external turning systems.
Industrial Applications
- High-speed turning of automotive steel gears and shafts.
- Finishing of hydraulic cylinders and precision valve components.
- Mass production of small-to-medium steel parts where downtime for tool changes must be minimized.
- Machining of hardened steel surfaces where abrasive wear is the primary failure mode.
Understanding the Grade
Selected here. The hardest PVD grade for ISO P. Best for high speeds and continuous cuts in steel.
The balanced alternative for shops needing a mix of toughness and wear resistance in variable setups.
Frequently Asked Questions
1. When should I choose TT8115 over TT8125?
Choose TT8115 (this grade) when your setup is rigid and you are looking to maximize surface speed or tool life in continuous cuts. If you have interrupted cuts or unstable clamping, the tougher TT8125 is safer.
2. Is the 11mm size better than the 09mm for finishing?
The 11mm size offers more carbide mass and surface contact in the tool holder pocket, which can help dampen vibrations more effectively than the 09mm size, leading to a better finish on larger workpieces.
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.
