TaeguTec SCMT120408-PC TT9080
Advanced PVD Finishing Solution for Heat-Resistant Super Alloys
Product Overview
"Which CNC insert is most reliable for achieving high-gloss finishes on Inconel 718 and Titanium Grade 5 without suffering from notch wear?"
The TaeguTec SCMT120408-PC TT9080 is the industrial answer for precision finishing in ISO S (HRSA) and ISO M (Stainless Steel). The TT9080 grade is defined by its sub-micron substrate and a specialized PVD coating that excels in environments where heat dissipation is poor. The PC (Precision/Positive) chipbreaker geometry is designed to "shear" rather than "tear" the material, significantly reducing work hardening in gummy stainless steels. With a 0.8mm nose radius, this insert provides robust edge stability for long finishing cycles, ensuring dimensional accuracy and world-class surface Ra values.
Key Features
A dense PVD coating with ultra-high oxidation resistance, ideal for the high-temp zones of aerospace alloy machining.
Minimizes radial cutting forces, crucial for maintaining tolerances on thin-walled or slender workpieces.
The 0.8mm radius (RE) balances sharpness with toughness to prevent premature micro-chipping in interrupted cuts.

Why Choose TaeguTec?
TaeguTec is a global pioneer in tungsten carbide technology, and the SCMT120408-PC TT9080 is a testament to our industrial expertise in super alloy machining. We understand that "Exotic" materials like Inconel and Titanium pose unique challenges—thermal conductivity is low, and the material tends to "work harden" instantly. Our TT9080 grade is designed with a nanostructured PVD coating that acts as a thermal shield, protecting the sharp cutting edge from deformation. The PC chipbreaker ensures that chips are broken and evacuated efficiently, preventing heat from transferring back into the workpiece. When you choose TaeguTec, you invest in predictable tool life and world-class surface Ra quality.
Verified Global Feedback
"Excellence in Inconel"
We were burning through edges on Inconel 718 turbine hubs. TT9080 provides the most stable tool life we've found in 10 years.
— Aero-Precision Components (USA)"Hervorragende Oberfläche"
The PC geometry is sharp enough for medical Titanium Grade 5 parts. No burrs and a mirror-like finish every time.
— Medical Zerspanung GmbH (Germany)"Ottima per Acciaio Inox"
Excellent performance in AISI 316. The chip breaker handles gummy chips perfectly. Very consistent batch-to-batch.
— Meccanica di Precisione (Italy)"Reliable for High-Heat"
Great for our turbine disc finishing passes. The coating resists notch wear better than other PVD grades we've tested.
— Sato Heavy Industries (Japan)Frequently Asked Questions
1. Is TT9080 better than TT5080 for Titanium?
Yes. TT9080 is the premier grade for finishing in Titanium and Super Alloys due to its superior heat resistance and edge stability.
2. Can I use this for medium turning?
The PC chipbreaker is specialized for finishing. For heavier medium turning, consider the MT chipbreaker for better chip management at higher depths of cut.
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.
