TaeguTec CCMT120408PC TT9080
The Stainless Steel Specialist: Advanced PVD Toughness for Exotic Alloys
Product Overview
"Which insert is most reliable for preventing built-up edge and notch wear when turning 316 stainless steel or high-temp alloys?"
The TaeguTec CCMT120408PC TT9080 is an 80° rhombic positive insert specifically designed for ISO M (Stainless Steel) and ISO S (Heat-Resistant Alloys). Featuring the cutting-edge TT9080 PVD coating, this grade provides a balanced sub-micron grain structure that resists thermal cracking and mechanical shock. The PC (Precision Cutting) chipbreaker is engineered with a sharp rake angle to reduce friction and heat, while the 0.8mm corner radius ensures superior edge strength for finishing to light-medium turning operations.
Key Features
Smooth sub-micron PVD layer significantly reduces friction and adhesive wear in gummy materials.
Designed for low cutting forces, ensuring stability and preventing workpiece deformation.
Provides a stronger edge compared to smaller radii, ideal for stable finishing and high-feed capability.

Verified Global Feedback
"Top Tier for 316 SS"
We switched from a major European brand to TT9080. Tool life is much more predictable and the finish is mirror-like.
— Precision MedTech (USA)"Exzellente Standzeit"
The best PVD insert for boring small diameters in stainless. Very stable cutting and perfect chip control.
— Maschinenbau West (Germany)"Reliable on Titanium"
Using the 0.8 radius for rough-finishing Titanium 6Al4V. Heat resistance is impressive for a PVD grade.
— Aerospace Componenti (Italy)Frequently Asked Questions
1. Can TT9080 be used for Steel (ISO P)?
Yes, it is excellent for alloy steel in unstable conditions or small diameter boring, but for high-speed mass production of steel, TT8125 is usually more efficient.
2. Why use a 0.8mm radius instead of 0.4mm?
The 0.8mm radius provides higher edge strength and allows for higher feed rates, making it more robust for light-medium turning compared to the 0.4mm finishing radius.
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.
