TaeguTec SNMG120404 TT9080
Precision Stainless Specialist: Ultimate PVD Toughness & Edge Sharpness
Product Overview
"Which CNC insert is most effective for finishing 316 Stainless Steel and Titanium while preventing work hardening and maintaining edge sharpness?"
The TaeguTec SNMG120404 TT9080 is specifically formulated for the challenges of gummy and hard-to-machine materials. Utilizing the TT9080 PVD grade, this insert features a specialized nanostructure coating that offers high hardness and exceptional oxidation resistance. The sharp 0.4mm nose radius minimizes radial cutting forces, making it perfect for light finishing cuts where vibration control and surface integrity are critical. Its double-sided square geometry provides 8 cost-effective cutting edges without compromising the precision required for ISO M and ISO S applications.
Key Features
Advanced AlTiN coating prevents built-up edge (BUE) and offers superior resistance to notch wear in Stainless Steel.
The 0.4mm radius ensures low cutting pressure, essential for maintaining dimensional accuracy in thin-walled or slender parts.
Specifically designed to handle the high heat and abrasive nature of Nickel-based superalloys and Titanium.

By choosing TaeguTec, you are securing an industrial partner that prioritizes edge security and surface excellence in the world's most difficult-to-machine materials.
Verified Global Feedback
"Stainless Savior"
Finally, an insert that doesn't build up edge on 316L. The finish on our medical parts is mirror-like. Incredible PVD quality.
— Precision Medical Inc (USA)"Exzellent für Titan"
Very tough insert. Even with interruptions in Titanium machining, the edge remains sharp. TT9080 is our new standard.
— Luftfahrt Komponenten AG (Germany)"Ottimo prodotto"
The 0.4mm radius is perfect for fine finishes on valve stems. Very stable and low vibration.
— Meccanica di Precisione (Italy)"Great Tool Life"
Handles heat very well in HRSA. We've seen a 30% increase in tool life over our previous brand.
— Tech-Flow Systems (Japan)Frequently Asked Questions
1. Why choose TT9080 over a CVD grade like TT7015?
TT9080 is a PVD grade, which allows for a much sharper cutting edge. This is crucial for Stainless Steel to prevent work hardening, whereas CVD grades are better for the high-speed heat of Carbon Steel.
2. Can I use this for roughing?
While it can rough light parts, the 0.4mm radius is primarily for finishing. For heavy roughing, we suggest the 0.8mm (08) or 1.2mm (12) radius versions.
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.
