TaeguTec CCMT060208PC TT9080
The Stainless Steel Specialist: Ultra-Hard PVD Coating for Heat-Resistant Alloys
Product Overview
"Which insert grade provides the best resistance to notch wear and built-up edge when machining 304/316 stainless steel or Inconel?"
The TaeguTec CCMT060208PC TT9080 is a high-performance 80° rhombic insert specifically engineered for ISO M (Stainless Steel) and ISO S (Exotic Alloys). Featuring an advanced sub-micron PVD (Physical Vapor Deposition) coating, the TT9080 grade excels in applications where thermal shock and abrasive wear are dominant factors. The PC (Precision Cutting) chipbreaker utilizes a sharp rake angle and positive geometry, designed to reduce radial cutting forces and prevent work-hardening in sensitive alloys, while the reinforced 0.8mm radius offers superior edge strength for finishing and light-medium turning.
Key Features
A thin, ultra-smooth TiAlN-based layer provides exceptional resistance to oxidation and friction in "sticky" materials.
Sharpened cutting edges significantly lower power consumption and heat generation during high-precision finishing.
Enhanced corner strength for longer tool life and improved surface finish consistency in demanding stainless applications.

Verified Global Feedback
"Ultimate Stainless Performance"
We use these on 316L valves. Tool life is twice as long as the previous Japanese brand. Incredible stability.
— Precision Fluidics (USA)"Sehr zuverlässig"
No built-up edge on sticky alloys. The surface finish remains consistent across long batches.
— Maschinenbau Nord (Germany)"Top notch for boring"
Using the 0.8 radius for boring operations on Inconel 718. Heat management is excellent.
— AeroSpace Tech (Italy)Frequently Asked Questions
1. Can TT9080 be used for Steel turning?
Yes, it is excellent for alloy steel in unstable conditions or small boring, but for high-speed continuous steel turning, TT8125 is generally more efficient.
2. Does this insert require wet machining?
For stainless steel and HRSA, wet machining (flood coolant) is highly recommended to extend tool life and improve 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.
