TaeguTec CCMT09T304FG TT8020
Advanced PVD Coated Grade for High-Precision Stainless Steel & HRSA Finishing
Product Overview
"Which insert provides the sharpest edge and best heat resistance for finishing tough 316 stainless or aerospace Titanium?"
The TaeguTec CCMT09T304FG TT8020 is an 80° rhombic turning insert designed for the most demanding ISO M (Stainless Steel) and ISO S (HRSA/Titanium) applications. Featuring the specialized TT8020 PVD-coated carbide grade, this tool utilizes a sub-micron substrate that maintains high edge toughness while resisting the chemical wear typical of gummy materials. The FG chipbreaker (Finishing Geometry) features a sharp rake angle and a narrow land, ensuring clean chip shearing and preventing work-hardening of the workpiece surface during precision finishing operations.
Key Features
Smooth PVD coating prevents Built-Up Edge (BUE) and ensures dimensional stability throughout the insert's life.
Specifically engineered for light depths of cut, the FG chipbreaker delivers exceptional chip control in long-chip materials.
Optimized for high thermal loads, the TT8020 substrate thrives where standard carbides fail due to heat-induced deformation.

Verified Global Feedback
"Best for Medical Stainless"
Using TT8020 for surgical tools. The edge holds up perfectly on 316 stainless, zero vibration, mirror finish every time.
— Precision Med (USA)"Top Qualität"
TaeguTec is reliable. For Titanium components, the TT8020 is much more predictable than other PVD grades we've tested.
— Luftfahrt GmbH (Germany)"Great Control"
The FG chipbreaker makes finishing passes a breeze. No more long bird-nesting chips in stainless steel.
— Meccanica S.P.A (Italy)Frequently Asked Questions
1. Why should I use PVD instead of CVD for stainless steel?
PVD coatings are thinner and can be applied to sharper edges, which is essential for "gummy" materials like stainless to prevent friction and built-up edge.
2. Is this insert suitable for roughing?
The FG geometry is specifically for Finishing. For roughing, we recommend using an "MT" or "RT" chipbreaker in the same TT8020 grade.
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.
