TaeguTec TCMT110208MT TT9080
The Universal PVD Choice for Stainless Steel & Exotic Alloys
Product Overview
"Which insert is the most versatile for a shop cutting various grades of stainless steel and titanium?"
The TaeguTec TCMT110208MT TT9080 is the industrial gold standard for versatility in Stainless Steel (ISO M) and High-Temperature Alloys (ISO S). The TT9080 PVD grade features a sub-micron substrate coupled with a specialized TiAlN coating, offering a perfect balance between hardness and toughness. The MT (Medium Turning) chipbreaker geometry utilizes a positive rake angle to shear gummy materials, effectively preventing Built-Up Edge (BUE). With a 0.8mm corner radius, this insert provides extra stability for continuous cuts and semi-roughing, ensuring a high-quality surface finish and predictable tool life across diverse workpiece materials.
Core Advantages
TT9080 is highly effective across various materials, making it the perfect choice for job shops handling frequent material changes.
The smooth PVD TiAlN surface reduces friction, preventing material welding and edge chipping in austenitic stainless steels.
The 0.8mm radius provides increased strength at the tip, allowing for higher feed rates and more aggressive machining depths.

— David L., USA"Fast shipping to Tokyo. The 0.8mm radius holds up perfectly during semi-roughing."
— Kenji S., Japan"Sehr zufrieden. Edge life on stainless shafts is doubled compared to our previous brand."
— Stefan R., Germany"Reliable PVD grade. No more issues with Built-Up Edge in the Italian workshop."
— Alessandro V., Italy"The 11mm MT breaker is my go-to for job shop production. Versatile and sharp."
— Mike W., USAFrequently Asked Questions
A: Yes, it is very effective for Carbon Steel, though CVD grades like TT8115 might offer better tool life in high-speed continuous steel turning.
A: For stainless steel and exotic alloys, we strongly recommend high-pressure coolant to manage heat and prevent gummy chips from welding to the insert.
A: The 0.8mm radius (08) offers much higher edge strength and allows for higher feed rates, making it more productive for medium turning applications.
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.
