TaeguTec TCMT16T308PC TT9225
Professional CVD Solution for High-Speed Steel Turning & Semi-Finishing
Product Overview
"Which insert provides the best combination of edge toughness and thermal resistance for semi-finishing carbon steels?"
The TaeguTec TCMT16T308PC TT9225 is a high-performance 16mm triangular insert specifically engineered for Steel (ISO P) machining. Utilizing the advanced TT9225 CVD grade, it features a robust Al2O3 coating layer that acts as a superior heat shield, enabling high cutting speeds (Vc) without compromising tool life. The PC (Positive Finishing) chipbreaker is designed with a sharp rake angle that effectively shears workpieces, reducing cutting forces and vibration. With an enhanced 0.8mm corner radius, this insert offers increased edge security for semi-finishing applications and interrupted cuts, making it the ideal choice for automotive and heavy machinery components.
Core Advantages
The thick CVD layer provides extreme resistance to crater wear during high-speed continuous cutting.
Reduces built-up edge (BUE) and ensures a clean chip curl even in softer low-carbon steels.
The larger 0.8mm radius allows for higher feed rates and better durability in slightly unstable conditions.

"The 0.8 radius is much more stable on our older CNC machines. TT9225 handles the heat perfectly."
— Mike S., USA"Ausgezeichnete Standzeit bei legiertem Stahl. Very reliable for semi-finishing."
— Andreas L., Germany"Genuine quality. Better chip control on mild steel than other brands I've tried."
— Kenji Y., Japan"Finitura superficiale incredibile su acciaio 4140. Consigliatissimo."
— Giuseppe R., Italy"Great productivity boost. We can run much faster with these CVD inserts."
— Tom B., UKFrequently Asked Questions
A: CVD grades like TT9225 handle heat well, but for optimal tool life and surface finish in steel, we recommend using flood coolant.
A: The 0.8mm radius is stronger and allows for higher feed rates (Fn). It is better for semi-finishing or parts that require a stronger corner.
A: While it can cut stainless, TT9225 is optimized for ISO P (Steel). For stainless steel turning, TaeguTec TT9080 is the superior choice.
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.
