TaeguTec TCMT110208MT TT7015
Advanced CVD Solutions for High-Velocity Steel and Iron Machining
Product Overview
"Which insert provides the best surface finish and wear resistance for high-speed continuous turning in steel?"
The TaeguTec TCMT110208MT TT7015 is a high-performance 11mm triangular turning insert optimized for Steel (ISO P) and Cast Iron (ISO K). Featuring the specialized TT7015 CVD grade, it utilizes a thick alumina coating to manage the extreme heat generated at high cutting speeds. The MT (Medium Turning) chipbreaker is designed with a balanced rake angle to ensure stable chip evacuation across a range of depths, while the 0.8mm corner radius delivers enhanced edge strength and superior surface productivity in demanding CNC environments.
Core Advantages
Specifically engineered for high surface footage (Vc), reducing cycle times in production turning of abrasive materials.
The larger 0.8mm radius (08) offers superior resistance to tip breakage compared to standard finishing inserts.
Multi-layer coating provides a powerful thermal barrier, preventing plastic deformation at high temperatures.

"Switched to TT7015 for our ductile iron parts. The 0.8mm radius holds up significantly better at 350 m/min."
— Dieter K., Germany"Excellent tool life on 4140 steel. Best price-to-performance ratio for 11mm inserts."
— Mark T., USA"Consegna rapida in Italia. Ottima finitura superficiale."
— Paolo R., Italy"Reliable chip control on our CNC lathes. No nesting issues."
— Kenji H., Japan"Essential for our high-speed production line. Genuine quality."
— Sarah L., USAFrequently Asked Questions
A: Yes. The thick alumina layer in the TT7015 CVD coating is specifically designed to resist heat, making it an excellent choice for dry turning in cast iron.
A: While it can cut stainless, the CVD coating is chemically optimized for Carbon/Alloy Steel and Iron. For Stainless Steel, we recommend the PVD-coated TT8020 or TT9080 grades.
A: The 08 radius provides more carbide at the tip, allowing for higher feed rates and providing more structural stability during continuous high-heat operations.
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.
