TaeguTec CCMT120404PC TT9080
The Stainless Steel Specialist: Ultra-Hard PVD Coating for Challenging Alloys
Product Overview
"Which insert grade provides the best balance of edge toughness and heat resistance when turning 304/316 stainless steel or Inconel?"
The TaeguTec CCMT120404PC TT9080 is a high-precision 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Heat-Resistant Alloys). Utilizing a sophisticated sub-micron PVD (Physical Vapor Deposition) coating, the TT9080 grade is engineered to combat the unique challenges of "gummy" materials, such as built-up edge (BUE) and notch wear. The PC (Precision Cutting) chipbreaker geometry features a sharp cutting edge and positive rake angle, specifically designed to reduce radial cutting forces and maintain thermal stability during high-precision finishing operations.
Key Features
Smooth, heat-resistant TiAlN-based coating reduces friction and prevents chemical wear at high temperatures.
Sharp geometry provides excellent chip control at light depths of cut, preventing work-hardening of the workpiece.
Specialized carbide substrate allows for reliable performance even in light interrupted cuts or unstable setups.

Verified Global Feedback
"Ultimate Performance on 316L"
We struggled with built-up edge using other brands. The TT9080 solved it instantly. The PC chipbreaker is fantastic for finishing.
— Precision Machining Co. (USA)"Beste für Edelstahl"
Very consistent tool wear even on tough heat-resistant alloys. Highly reliable for our production lines.
— Maschinenbau AG (Germany)"Top Tier PVD"
Using this for aerospace boring. Heat management is excellent and the surface finish is impeccable.
— AeroSpace Components (Italy)Frequently Asked Questions
1. Can TT9080 be used for Steel (ISO P)?
Yes, it is excellent for alloy steel in unstable conditions or small diameter boring, but for high-speed mass production of steel, TT8125 is usually more efficient.
2. Why use a 0.4mm radius instead of 0.8mm?
The 0.4mm radius (016) is ideal for finishing operations requiring high dimensional accuracy and lower radial cutting forces, especially in boring or thin-walled parts.
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.
