TaeguTec CCMT09T304PC TT9080
The Stainless Steel & Exotic Alloy Specialist: High-Toughness PVD Coating
Product Overview
"Which insert grade provides the longest tool life and best surface finish when machining austenitic stainless steel or gummy heat-resistant alloys?"
The TaeguTec CCMT09T304PC TT9080 is a high-performance 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Heat-Resistant Alloys). Featuring the advanced sub-micron PVD (Physical Vapor Deposition) coating, the TT9080 grade is specifically engineered to handle the work-hardening characteristics of stainless materials. The PC (Precision Cutting) chipbreaker geometry utilizes a sharp rake angle to minimize cutting heat and vibration, ensuring superior chip evacuation in finishing and light turning operations.
Key Features
The ultra-smooth PVD layer reduces friction and prevents built-up edge (BUE), a common failure point in stainless machining.
Designed for low cutting forces, this chipbreaker prevents workpiece deflection in small-diameter boring.
Specialized carbide substrate provides extreme resistance to thermal cracking and mechanical shock.

Verified Global Feedback
"Flawless on 316L"
We were getting built-up edge with our previous brand. Switched to TT9080 and haven't had a single issue in 500 parts. Excellent finish.
— Precision MedTech (USA)"Tolle Standzeit"
Very stable performance in titanium. The PC chipbreaker works perfectly even at very low depths of cut.
— AeroMach AG (Germany)"Ottimo per inox"
High-quality PVD coating. Reduced our tool costs per part by 15% on stainless valves.
— Meccanica Nord (Italy)Frequently Asked Questions
1. Is TT9080 better than CVD grades for stainless steel?
Generally, yes. PVD grades like TT9080 have sharper edges and are tougher than CVD grades, making them better for the work-hardening nature of stainless steel.
2. Can I use this for Titanium?
Absolutely. TT9080 is an excellent choice for ISO S materials like Titanium and Inconel due to its heat resistance and edge toughness.
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.
