TaeguTec TCMT110208PC TT9080
Enhanced Edge Strength for Stainless Steel Semi-Finishing & Finishing
Product Overview
"Which insert provides the highest reliability for finishing stainless steel parts with a slightly higher feed rate?"
The TaeguTec TCMT110208PC TT9080 is an 11mm triangular turning insert specifically developed for Stainless Steel (ISO M) and Superalloys (ISO S). Featuring the robust 0.8mm corner radius, this model provides significantly better edge strength and heat dissipation compared to the 0.4mm version. The TT9080 PVD grade uses a specialized sub-micron substrate and a dense TiAlN coating to combat the high thermal loads typical of Inconel and 316 Stainless. Combined with the PC (Positive Finishing) chipbreaker, it shears cleanly through gummy materials, ensuring stable chip evacuation and preventing Built-Up Edge (BUE) even in semi-finishing depths of cut.
Core Advantages
Superior resistance to crater wear and oxidation, essential for high-temperature alloy machining.
Offers a stronger cutting edge for semi-finishing passes while maintaining excellent surface finish quality.
The sharp positive rake angle reduces cutting forces and eliminates tool pressure on delicate parts.

"The 0.8mm radius is much tougher. I can run these at higher feeds on 304 stainless without chipping."
— John T., USA"Perfect for internal semi-finishing. TT9080 stands up to the heat of titanium beautifully."
— Eric F., Germany"Consistent tool life and very reliable. Best PVD grade for stainless we've used."
— Yuki H., Japan"Ottimo per acciai inox, finitura superficiale eccellente anche a metà passata."
— Fabio V., Italy"Arrived fast. The TCMT 11 PC breaker is our standard for all finishing work now."
— Sam B., UKFrequently Asked Questions
A: Yes. For stainless steel and high-temp alloys, high-pressure coolant is essential to evacuate chips and control the extreme heat at the cutting edge.
A: The 0.8mm radius is physically stronger and can handle higher feed rates (fn). It is better suited for semi-finishing where depth of cut is slightly higher.
A: You can, but it is not optimal. PVD grades run slower than CVD grades. For carbon steel, we recommend CVD grades like TT9225 for higher productivity.
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.
