TaeguTec TCMT090204PC TT9225
High-Speed CVD Technology for Precision Steel Finishing
Product Overview
"Which insert is the best for high-speed finishing of carbon and alloy steels while maintaining long tool life?"
The TaeguTec TCMT090204PC TT9225 is a professional 9mm triangular turning insert engineered for Steel (ISO P) applications. Featuring the advanced TT9225 CVD grade, this insert is built with a thick Al2O3 coating layer that provides exceptional heat resistance and crater wear protection at high cutting velocities. The PC (Positive Finishing) chipbreaker is specifically designed for light depths of cut, utilizing a sharp cutting edge to reduce friction and heat. This makes it the ideal choice for automotive and general machinery parts where high-efficiency throughput and a mirror-like surface finish are required on steel workpieces.
Key Features
The TT9225 grade allows for significantly higher cutting speeds (Vc) compared to PVD grades, reducing cycle times.
Sharp positive rake angle ensures clean shearing of steel fibers, delivering superior dimensional accuracy.
The PC breaker prevents long, stringy chips in soft steels, ensuring a safe and automated machining process.

"TT9225 grade is a beast on 1045 steel. I doubled my cutting speed compared to my old PVD inserts."
— Robert K., USA"Hervorragende Oberflächengüte bei legiertem Stahl. Die Standzeit ist beeindruckend."
— Dieter W., Germany"Excellent finishing accuracy for small precision pins. Fast shipping to Tokyo."
— Hiroshi T., Japan"Ottima resistenza all'usura su acciai bonificati. Molto soddisfatto."
— Marco G., Italy"The PC breaker works perfectly on my manual lathe too. Clean chips every time."
— James L., UKFrequently Asked Questions
A: While it can cut stainless, it is not optimized for it. CVD grades like TT9225 can suffer from micro-chipping in gummy stainless. We recommend TT9080 (PVD) for ISO M materials.
A: The PC geometry is a finishing specialist. We recommend a depth of cut (Ap) between 0.1mm and 1.2mm for best results.
A: CVD coatings are thicker and more heat-resistant, allowing you to run much higher surface speeds (Vc), which directly increases parts-per-hour.
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.
