TaeguTec TCMT16T304MT TT8115
High-Speed Industrial Productivity: Maximum Wear Resistance and Stability for Large Diameter Steel Turning
Product Overview
"Combine the mass of a 16mm triangular substrate with the hardness of the TT8115 grade to dominate high-speed finishing runs in steel."
The TaeguTec TCMT16T304MT TT8115 is a robust 16mm triangular turning insert engineered for high-performance Steel (ISO P) applications. This insert is designed for large-scale components where cycle time reduction is critical. The TT8115 grade is TaeguTec's most wear-resistant PVD coating in the 8100 series, providing a harder surface that excels in continuous cuts at high surface speeds. The MT (Medium Turning) chipbreaker offers a versatile positive rake geometry that effectively manages chip flow in both medium turning and precision finishing. With a 0.4mm corner radius, this insert provides the ultimate surface finish and dimensional precision for high-output CNC environments.
Core Advantages
A specialized PVD coating designed specifically to resist abrasive wear at high temperatures, perfect for high-speed automated lines.
The increased carbide volume provides exceptional thermal dissipation and structural rigidity, preventing edge deformation during long cuts.
Optimized for reduced cutting forces, this chipbreaker prevents heat transfer into the workpiece, ensuring superior surface integrity.

Industrial Applications
- High-speed finishing of large automotive and industrial steel shafts.
- Precision turning of alloy steel components for the energy sector.
- Internal boring of long-reach steel housings requiring stable thermal management.
- Continuous high-output machining of carbon steel parts on automated CNC lathes.
Choosing the Grade
Selected here. The hardest PVD option. Designed for maximum surface speed and long tool life in rigid steel setups.
The alternative for shops requiring higher edge toughness for light interruptions or less stable workholding.
Frequently Asked Questions
1. When is TT8115 better than TT8125 in a 16mm size?
Use TT8115 (this grade) when you have a very stable setup and are machining high-carbon or abrasive alloy steels at high speeds. It provides a harder cutting edge that resists wear significantly longer than TT8125.
2. Does this work for finishing small parts?
While it can, the 16mm size is usually optimized for medium-to-large workpieces. The 0.4mm radius is perfect for fine finishes, but for small diameter internal boring, consider the 09 or 11mm sizes for better clearance.
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.
