TaeguTec CNMG120412PC TT9080
Precision Finishing in Tough Materials: Sub-Micron PVD Grade for Exotic Alloys
Product Overview
"Which turning insert grade offers the best chip control and thermal stability when finishing gummy stainless steels or heat-resistant super alloys?"
The TaeguTec CNMG120412PC TT9080 is the definitive solution for high-precision finishing in ISO M (Stainless Steel) and ISO S (Super Alloys). The TT9080 PVD grade features an ultra-fine sub-micron substrate coated with advanced thermal protection layers to prevent chemical wear and built-up edge (BUE). The PC (Positive Finishing) chipbreaker geometry is ground to a sharp edge, providing low cutting resistance while the 1.2mm radius offers significant edge strength for consistent production runs.
Key Features
Excellent toughness combined with a thin, smooth PVD coating that prevents chip welding on sticky materials.
Positive rake angle design reduces work hardening of the workpiece surface, critical for aerospace alloys.
The larger corner radius dissipates heat more effectively and allows for higher feed rates without compromising finish.

Verified Global Feedback
"Perfect for Stainless 316"
We turn 316L pump parts and built-up edge was always a struggle. The TT9080 grade solved it. Incredible finish.
— Precision Fluidics (Germany)"Reliable on Titanium"
Used these for finishing aerospace bushings. The 1.2 radius provides great heat dissipation and the edge stays sharp far longer than competitors.
— Aero-Machining (USA)"Consistent Quality"
Very predictable tool life across our production batches. The PC breaker is ground beautifully for low depth-of-cut passes.
— High-Spec Parts (Italy)Frequently Asked Questions
1. Is TT9080 suitable for dry machining?
While highly heat resistant, for finishing Stainless and Super Alloys, we strongly recommend high-pressure coolant to ensure optimal chip evacuation and surface quality.
2. Can I use the PC breaker for roughing?
No, the PC (Positive Finishing) breaker is designed for low-force finishing. For heavier roughing, consider MT or RT chipbreaker geometries.
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.
