TaeguTec CCMT09T304PC TT9225
Engineered for High-Speed Steel Turning: The CVD Precision Powerhouse
Product Overview
"Which insert grade provides the best thermal stability and wear resistance for high-volume production of steel and stainless parts?"
The TaeguTec CCMT09T304PC TT9225 is a high-performance 80° rhombic insert designed for ISO P (Steel) and ISO M (Stainless Steel). Featuring the advanced TT9225 CVD coating, this grade excels in high-temperature cutting environments, offering a robust barrier against crater wear and plastic deformation. The PC (Precision Cutting) chipbreaker is meticulously crafted with a positive rake and sharp geometry, ensuring excellent chip control at light depths of cut and maintaining high surface Ra standards during finishing operations.
Key Features
Thick Al2O3 layer offers superior heat insulation, allowing for significantly higher cutting speeds and longer tool life.
Low-vibration design ensures stable machining in small boring applications and thin-walled workpieces.
The TT9225 substrate provides the perfect synergy between crater wear resistance and mechanical toughness.

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.
— Precision Machining (USA)"Top Tier Grade"
Replaced our previous brand with TT9225. We were able to increase cutting speed by 20% without losing life.
— Maschinenbau West (Germany)"Best for finishing"
The PC chipbreaker handles fine chips perfectly on small diameters. Excellent for boring stainless.
— 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 to light interrupted turning.
2. Can I use this grade without coolant?
While TT9225 has high heat resistance, using flood coolant is recommended for stainless steel to prevent built-up edge and ensure chip evacuation.
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.
