TaeguTec CCMT060204FG TT8020
High-Performance PVD Coated Grade for Exotic Alloys & Stainless Steels
Product Overview
"Which insert is most effective for finishing Titanium or Inconel where heat resistance and edge sharpness are critical?"
The TaeguTec CCMT060204FG TT8020 is an 80° rhombic positive turning insert specifically engineered for the ISO S (HRSA) and ISO M (Stainless Steel) material groups. This insert features the elite TT8020 PVD-coated carbide grade, which utilizes a specialized sub-micron substrate to maintain a razor-sharp cutting edge while offering superior resistance to thermal fatigue. The FG chipbreaker (Finishing Geometry) is designed with a narrow land and a sharp rake angle to ensure excellent chip evacuation at shallow depths of cut, preventing work hardening in sensitive materials like 304/316 stainless and aerospace alloys.
Key Features
Advanced PVD technology provides a smooth, thin coating that preserves edge sharpness while resisting chemical wear and built-up edge (BUE).
Optimized for light-load finishing. The FG geometry breaks chips efficiently even at low feed rates, ensuring a high-quality surface finish.
The TT8020 grade is built to withstand the extreme thermal loads generated by low-thermal-conductivity materials like Titanium.

Verified Global Feedback
"Flawless on Titanium"
We use TT8020 for Titanium aircraft parts. The edge stays sharp far longer than other brands we've tried. Very consistent results.
— Aero Precision (USA)"Top Qualität auf Edelstahl"
The chip control with the FG geometry on 316 stainless is perfect. Surface quality is excellent for medical components.
— Med-Tech GmbH (Germany)"Molto Resistente"
Very stable dimensions across large batches of Inconel. Reduced our tool changes per shift significantly.
— Precisione S.R.L. (Italy)"Quality You Can Trust"
TaeguTec is my go-to for exotic alloys. The TT8020 grade is very dependable in the machine.
— T. Tanaka (Japan)Frequently Asked Questions
1. Can TT8020 be used for interrupted cuts?
TT8020 is a very tough PVD grade and can handle light interruptions. However, for heavy roughing with severe interruptions, a grade with a tougher core like TT8080 might be more suitable.
2. Why choose PVD for Stainless Steel finishing?
PVD coatings are thinner and can be applied to sharper cutting edges. This reduces friction and built-up edge, which is essential for a high-quality finish on gummy materials like stainless steel.
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.
