TaeguTec SCMT09T308-FG TT5080
Precision Finishing Specialist: Advanced PVD Coating for Stainless Steel
Product Overview
"Which CNC insert provides the most stable chip control and longest tool life when finishing gummy stainless steel components at high precision?"
The TaeguTec SCMT09T308-FG TT5080 is the ultimate industrial choice for fine finishing ISO M (Stainless Steel) and ISO P (Steel). The TT5080 grade is defined by its nanostructured PVD coating which offers exceptional resistance to built-up edge (BUE)—the primary enemy of surface finish in stainless machining. The FG (Fine Geometry) chipbreaker is meticulously designed with a sharp cutting edge and a specific rake angle that "ploughs" through the material, ensuring that even at very small depths of cut, chips are broken effectively and evacuated without marring the workpiece surface.
Key Features
High-aluminum content AlTiN coating ensures extreme heat resistance and superior edge toughness for interrupted cuts.
Specialized for finishing depths of cut (0.5mm - 1.5mm), preventing the "stringy" chips common in austenitic stainless steel.
The ultra-smooth surface of the TT5080 grade reduces friction, significantly lowering the risk of material welding to the tool tip.

| TT5080 | PVD (Thin) | The Sharp Choice: Best for finishing and low cutting forces. |
| TT9225 | CVD (Thick) | The Tough Choice: Best for high speed and medium turning. |
Why Choose TaeguTec?
TaeguTec is a global pioneer in metalworking technology, and the SCMT09T308-FG TT5080 is a testament to our industrial expertise in finishing. We understand that in precision CNC machining, the difference between a perfect part and scrap is measured in microns. Our TT5080 grade is designed with an AlTiN PVD coating that acts as a thermal shield, protecting the sharp cutting edge from deformation. The FG geometry ensures that chips are broken and evacuated quickly, preventing heat transfer into the workpiece. When you choose TaeguTec, you invest in predictable tool life and world-class surface Ra quality.
Verified Global Feedback
"Perfect for 316 Stainless"
We were struggling with stringy chips on our medical parts. The FG geometry solved it instantly. Surface finish is mirror-like.
— Precision MedTech (USA)"Spitzenqualität"
Outstanding tool life in alloy steel finishing. The TT5080 grade handles the heat much better than other PVD brands we've tested.
— CNC-Zerspanung GmbH (Germany)"Ottima stabilità"
Dimensional stability is key for us. This insert holds tolerances over long batches without needing constant offsets.
— Meccanica di Precisione (Italy)"Very Sharp"
Very sharp edge, great for low-vibration finishing. Wish the price was lower, but you get what you pay for in quality.
— Sato Precision (Japan)Frequently Asked Questions
1. What is the difference between FG and PC chipbreakers?
The FG (Fine Geometry) is specifically for lighter finishing depths (typically under 1.5mm), while the PC (Precision) chipbreaker handles a slightly broader finishing to semi-finishing range.
2. Can I use this grade for machining Aluminum?
While it can cut aluminum, it's not optimal. For non-ferrous materials, we recommend uncoated, polished grades for better chip flow and lower adhesion.
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.
