TaeguTec CCMT09T304MT TT5080
The Toughness Specialist: Premium PVD Turning in Stainless Steel & Alloys
Product Overview
"Which insert grade provides the best edge security and prevents work hardening when machining gummy stainless steels or high-temp alloys?"
The TaeguTec CCMT09T304MT TT5080 is a high-performance 80° rhombic insert optimized for ISO M (Stainless Steel) and ISO S (Super Alloys). Utilizing a sophisticated PVD coating, the TT5080 grade features an ultra-fine substrate that provides extreme edge sharpness and high resistance to built-up edge (BUE). The MT chipbreaker (Medium Turning) is specifically designed for tough materials, featuring a positive geometry that shears through the workpiece smoothly, significantly reducing cutting forces and surface work hardening.
Key Features
Specifically engineered to resist thermal cracking and chipping in difficult-to-cut materials.
Positive rake angle prevents BUE, ensuring consistent dimensions and clean surface finishes.
Excel in both continuous and interrupted cuts in Austenitic Stainless Steels and Inconel.

Verified Global Feedback
"Perfect for 316 Stainless"
We struggled with built-up edge until we switched to TT5080. The surface finish is consistently clean and the edges hold up brilliantly.
— Medical Device Mfg (USA)"Exzellente Zähigkeit"
Great for interrupted cuts in Inconel. We've significantly reduced our scrap rate thanks to this grade's stability.
— Aerospace Hub (Germany)"Ideale per Inox"
Very sharp and reliable. It handles the work-hardening tendencies of stainless steel better than any other PVD grade we've used.
— Meccanica di Precisione (Italy)Frequently Asked Questions
1. Why choose PVD (TT5080) over CVD for Stainless?
PVD coatings are thinner and allow for a much sharper cutting edge, which is essential to prevent built-up edge (BUE) and work hardening in gummy materials like stainless.
2. Can I use this for dry machining?
For stainless steel and super alloys, high-pressure coolant is highly recommended to control chip temperature and improve 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.
