TaeguTec CNMG120404MP TT5080
Engineered for Excellence: High-Toughness PVD Grade for Exotic & Super Alloys
Product Overview
"Which insert grade provides the best thermal stability and edge toughness when machining Inconel, Titanium, or high-alloy Stainless Steel?"
The TaeguTec CNMG120404MP TT5080 is an 80° rhombic turning insert specifically developed for ISO M (Stainless Steel) and ISO S (Heat Resistant Super Alloys). The TT5080 PVD grade is built on a sub-micron substrate that offers exceptional resistance to notch wear and thermal cracking. Combined with the MP (Medium-Positive) chipbreaker, it strikes the perfect balance between cutting edge sharpness and structural strength, ensuring stable performance in challenging high-heat applications.
Key Features
A specialized coating designed to withstand the extreme temperatures generated during the machining of exotic alloys.
Medium-positive geometry ensures low cutting forces while providing superior chip evacuation on gummy materials.
Ideal for medium-to-fine finishing passes requiring mirror-like surface integrity and tight tolerances.

Verified Global Feedback
"The Standard for Titanium"
We use these for Ti-6Al-4V aerospace components. The MP breaker holds up beautifully against notch wear where other brands failed.
— Aero-Tech Components (USA)"Reliable on Stainless"
Great for 316 stainless. No built-up edge and very predictable tool life across our CNC shifts. Highly recommended.
— Precision Machining GmbH (Germany)"Excellent Finish"
The 0.4mm radius is perfect for fine detail. Tool geometry is very sharp and reduces vibration on our light passes.
— Advanced Precision (Japan)Frequently Asked Questions
1. Is the MP breaker suitable for heavy roughing?
The MP (Medium-Positive) breaker is designed for medium turning and light finishing. For heavy roughing of super alloys, we recommend the RT or MT geometries.
2. How does TT5080 perform with dry machining?
While TT5080 is highly heat resistant, for exotic alloys and stainless steel, high-pressure coolant is strongly recommended to maintain surface quality and tool life.
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.
