TaeguTec DCMT11T302FA TT5080
The Ultimate Edge: Precision PVD Solutions for Super Alloys & Stainless Steel
Product Overview
"Which turning insert provides the highest reliability when finishing heat-resistant alloys without sacrificing edge sharpness?"
The TaeguTec DCMT11T302FA TT5080 is a high-performance turning insert specifically optimized for ISO S (High-Temp Alloys/Titanium) and ISO M (Stainless Steel). Featuring the ultra-tough TT5080 PVD Coated grade, this insert is designed to withstand the extreme thermal loads generated by aerospace materials. The FA (Finishing-Automotive) chipbreaker is peripheral ground to a razor-sharp edge, providing exceptional shearing action and chip control at very light depths of cut, ensuring a high-gloss surface finish even on slender, vibration-prone workpieces.
Key Features
A sub-micron carbide substrate paired with a high-lubricity PVD coating that prevents built-up edge and resists notch wear.
Ground periphery ensures a clean shearing action, reducing cutting pressure and preventing work-hardening of the workpiece.
Optimized for stable finishing cycles in Inconel, Titanium, and Duplex Stainless Steels where edge integrity is critical.

Verified Global Feedback
"Perfect for Titanium"
We use these for finishing titanium bone plates. The Ra finish is incredible and the edge stays sharp for a high part count.
— Med-Core Systems (USA)"Hervorragend bei Inconel"
Finally found an insert that handles notch wear on Inconel 718 properly. Very stable and consistent dimensions.
— Aero-Bauteile AG (Germany)"Reliable for Swiss Lathes"
Great chip control on small diameter stainless parts. FA breaker prevents any bird-nesting on the finish pass.
— Precision Swiss (Italy)Frequently Asked Questions
1. What makes TT5080 better for super alloys?
TT5080 utilizes a specialized thin PVD coating that allows the cutting edge to remain razor-sharp while providing the thermal stability needed for HRSA materials.
2. Can this be used for semi-roughing?
No. The FA breaker and 0.2mm radius are strictly for light finishing. For semi-roughing, we recommend a larger radius and a sturdier chipbreaker like FG.
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.
