TaeguTec CCMT09T308MT TT9080
The PVD Performance Leader: Specialized for Stainless Steel & Super Alloys
Product Overview
"Which insert grade provides the best edge security and prevents work hardening when machining gummy stainless steels or high-temp alloys at medium speeds?"
The TaeguTec CCMT09T308MT TT9080 is a high-performance 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Super Alloys). Utilizing a sophisticated sub-micron PVD coating, the TT9080 grade features an ultra-fine grain substrate that provides extreme edge sharpness and superior resistance to built-up edge (BUE). The MT chipbreaker (Medium Turning) is paired with a strong 0.8mm corner radius, designed to shear through tough materials smoothly while significantly reducing cutting forces and thermal impact on the workpiece.
Key Features
Offers a unique combination of hardness and toughness, preventing micro-chipping in interrupted cuts.
The 0.8mm radius (032) provides excellent mechanical strength for heavy-duty finishing of hard alloys.
Engineered to control chips effectively across a wide range of feed rates in gummy materials.

Global Verified Feedback
"Perfect for Inconel"
We struggled with chipping on our Inconel parts until we switched to TT9080. The toughness is incredible.
— Aero-Tech Solutions (USA)"Top für Edelstahl"
Great chip control on 316 stainless. The MT chipbreaker makes all the difference in finish quality.
— Precision Machining (Germany)"Affidabile e Tagliente"
Very sharp edges. Excellent for our small-batch precision stainless fittings.
— Meccanica di Lusso (Italy)Frequently Asked Questions
1. Why choose TT9080 for stainless steel?
TT9080 uses a sub-micron PVD coating that allows for a much sharper edge than CVD, which is vital to prevent built-up edge and work hardening in stainless steel.
2. Is a 0.8mm radius too large for finishing?
The 0.8mm radius provides much better edge strength and surface finish at higher feed rates, but ensure your setup is rigid to avoid vibration.
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.
