TaeguTec DCMT070204FG TT5080
Mastering Stainless Steel: Advanced PVD Coating for High-Toughness Precision
Product Overview
"Which insert is most reliable for precision finishing in gummy stainless steels while preventing built-up edge?"
The TaeguTec DCMT070204FG TT5080 is the ultimate solution for finishing ISO M (Stainless Steel) and ISO S (High-Temperature Alloys). Unlike standard grades, the TT5080 features a nano-structured PVD coating that excels in preventing Built-Up Edge (BUE) and providing high thermal stability. The FG (Finishing-General) chipbreaker is engineered with a sharp, ground cutting edge and a specific geometry that ensures excellent chip evacuation even at low feed rates. This insert is ideal for parts requiring tight tolerances and superior surface integrity in challenging materials.
Key Features
High-toughness sub-micron substrate with advanced PVD coating for superior resistance to oxidation and heat.
Optimized chip control for finishing cycles, minimizing tool pressure to prevent deflection in slender workpieces.
A sharp corner radius that enables precise profile turning and excellent Ra finish on internal and external diameters.

Global Industry Feedback
"Reliable for 316L"
We use these for surgical valve components. The TT5080 grade stays sharp far longer than competitive PVD grades we've tested.
— MedTech Manufacturing (USA)"Top für Edelstahl"
Excellent surface Ra values. Chip control with the FG breaker is very consistent even at small depths.
— Präzision Guss GmbH (Germany)"Ottima stabilità"
No built-up edge issues on titanium turning. Very impressed with the thermal resistance.
— Meccanica di Precisione (Italy)Frequently Asked Questions
1. Is the TT5080 grade suitable for high-speed machining?
Yes, the PVD TiAlN coating is designed for high thermal resistance, allowing for higher cutting speeds in stainless steel compared to standard carbide.
2. What is the benefit of the FG chipbreaker for stainless steel?
Stainless steel is prone to long, stringy chips. The FG breaker is ground to force chip breakage at small depths, protecting the workpiece surface.
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.
