TaeguTec DCMT070202FA TT9080
Mastering Stainless Steel: High-Toughness PVD Solution for Precision Finishing
Product Overview
"Which turning insert is best for finishing stainless steel parts while maintaining sharp edge integrity and preventing notch wear?"
The TaeguTec DCMT070202FA TT9080 is a high-precision turning solution specifically optimized for ISO M (Stainless Steel) and ISO S (High-Temperature Alloys). Featuring the ultra-tough TT9080 PVD Coated grade, this insert excels in environments where work-hardening and thermal shock are prevalent. The FA (Finishing-Automotive) chipbreaker is ground to a razor edge, providing exceptional chip control at very light depths of cut, ensuring a high-gloss surface finish and preventing vibration in slender workpieces.
Key Features
A specialized PVD coating over a sub-micron substrate that provides superior resistance to notch wear and edge chipping.
Peripheral ground geometry ensures a clean shearing action, reducing cutting temperature and work-hardening of the surface.
The FA chipbreaker is designed to break chips effectively at low feed rates, preventing "bird-nesting" on precision parts.

Verified Global Feedback
"Best for 316 Stainless"
We struggled with notch wear on our 316 valves. Switched to TT9080 and tool life increased by 40% with a much cleaner finish.
— Precision Fluidics (USA)"Perfekt für Medizintechnik"
The FA chipbreaker is incredibly sharp. Perfect for small medical screws where we need zero burrs on the stainless finish.
— Med-Tech GmbH (Germany)"Stable in Titanium"
Handles the heat of titanium turning very well. The 0.2mm radius stays sharp much longer than competing brands.
— Aero-Machining (Italy)Frequently Asked Questions
1. What makes TT9080 suitable for Stainless Steel?
TT9080 uses an ultra-fine substrate and a thin PVD coating that maintains a sharp edge while resisting the heat and work-hardening common in stainless alloys.
2. Can this insert be used for dry machining?
While TT9080 has high heat resistance, we highly recommend flood coolant when machining stainless steel to maximize surface finish and 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.
