TaeguTec SCMT120404-PC TT9080
Mastering Super Alloys: Precision PVD Technology for High-Heat Environments
Product Overview
"Which CNC insert is most effective for maintaining tight tolerances and a mirror-like finish in Titanium or Inconel finishing passes?"
The TaeguTec SCMT120404-PC TT9080 is the premier industrial choice for finishing ISO S (HRSA) and ISO M (Stainless). The TT9080 grade is defined by its exceptional thermal stability, preventing chemical wear and notch formation in abrasive super alloys. The PC (Precision) chipbreaker features a highly positive rake angle and sharp cutting edge, designed to "slice" through gummy materials rather than tear them. This prevents the work-hardening common in austenitic stainless and nickel-based alloys. With its 0.4mm nose radius, it is the ideal tool for components requiring extreme Ra values and precision geometries.
Key Features
Advanced AlTiN coating offers extreme hardness and heat resistance up to 900°C, perfect for dry or wet exotic alloy turning.
Specifically engineered for low cutting forces, reducing vibration in long-overhang or thin-walled applications.
High resistance to built-up edge (BUE) ensuring that surface finish remains consistent from the first part to the last.

Why Choose TaeguTec?
TaeguTec is a global leader in advanced carbide solutions, and the SCMT120404-PC TT9080 represents the absolute pinnacle of finishing technology. Machining super alloys isn't just about hard metal; it's about managing extreme thermal energy at the cutting edge. Our TT9080 grade is designed with an AlTiN nanostructure that actually gets tougher under heat, protecting the micro-grain substrate. The PC chipbreaker ensures that chips are broken and evacuated quickly, preventing the heat from transferring into the workpiece. When you choose TaeguTec, you are choosing industrial reliability that reduces scrap rates and tool-change downtime.
Verified Global Feedback
"Flawless Inconel 718 finish"
We were burning through edges on turbine hubs. The TT9080 stable tool life allowed us to complete the pass without stopping for offset adjustments.
— Aero-Tech Components (USA)"Spitzenklasse in Titan"
Outstanding for medical components. The sharpness of the PC geometry ensures no burrs on Titanium Grade 5 parts.
— Medical Zerspanung GmbH (Germany)"Ottima stabilità dimensionale"
Consistently holds 0.01mm tolerance on long shafts made of 316L. The finish is fantastic with the 04 radius.
— Meccanica di Precisione (Italy)"Consistent Quality"
Very sharp and reliable. The chip breaking at 0.05mm feed is very clean, which is hard to find for super alloys.
— Sato Precision (Japan)Frequently Asked Questions
1. Is TT9080 suitable for dry machining super alloys?
While the coating can handle the heat, we always recommend high-pressure coolant when machining ISO S materials to maximize tool life and chip evacuation.
2. Can I use this for medium turning if my depth of cut increases?
The PC chipbreaker is specialized for fine finishing (low DOC). If you need to step up to medium turning, consider the MT chipbreaker for better chip control at higher depths.
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.
