TaeguTec CCMT09T308PC TT9225
High-Speed Productivity: The Ultimate CVD Grade for Steel & Stainless Steel
Product Overview
"Which carbide insert grade provides the longest tool life when turning alloy steel at high speeds while maintaining chip control?"
The TaeguTec CCMT09T308PC TT9225 is a high-performance 80° rhombic insert optimized for ISO P (Steel) and ISO M (Stainless Steel). Featuring the advanced TT9225 CVD (Chemical Vapor Deposition) coating, this insert is built for heat resistance and durability in mass-production environments. The PC (Precision Cutting) chipbreaker geometry utilizes a sharp rake angle to reduce cutting forces, while the 0.8mm corner radius provides enhanced edge strength, making it ideal for finishing to light-medium turning operations.
Key Features
Thick Al2O3 layer provides excellent thermal insulation, allowing for significantly higher cutting speeds without crater wear.
Designed for low-force cutting, preventing vibration and ensuring impeccable surface finish on delicate workpieces.
The 0.8mm radius (031") improves tool life and allows for higher feed rates compared to standard finishing inserts.

Verified Global Feedback
"Versatile and Efficient"
We use TT9225 for alloy steel and 304 stainless. Tool life is very consistent and surface Ra is excellent. The 0.8 radius is much more robust for our rougher finishing passes.
— Precision Machining (USA)"Top Tier Grade"
Increased cutting speed by 25% compared to our previous supplier. The PC chipbreaker works perfectly on fine chips.
— Maschinenbau West (Germany)"Stable on Stainless"
Very impressive thermal resistance. Using this for high-volume automotive parts, zero issues with deformation.
— AeroSpace Tech (Italy)Frequently Asked Questions
1. Is TT9225 better than PVD grades for interrupted cuts?
For heavy interrupted cuts, a PVD grade like TT9080 is often tougher. TT9225 (CVD) is optimized for higher speeds and thermal stability in continuous turning.
2. Why choose a 0.8mm radius over 0.4mm?
The 0.8mm radius offers significantly higher edge strength and can handle higher feed rates, making it more durable for general turning where finishing isn't ultra-delicate.
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.
