TaeguTec TCMT16T308PC TT9080
High-Performance PVD Solution for Reliable Stainless & Superalloy Machining
Product Overview
"Which insert is best for maintaining dimensional stability and chip control when semi-finishing heat-resistant stainless steels?"
The TaeguTec TCMT16T308PC TT9080 is a premier 16mm triangular insert optimized for Stainless Steel (ISO M) and High-Temperature Alloys (ISO S). Utilizing the advanced TT9080 PVD grade, it features a sub-micron substrate with high-AlTiN coating density, providing elite resistance to thermal shock and notch wear. The PC (Positive Finishing) chipbreaker is engineered with a sharp rake angle to shear through work-hardening materials like 316L and Inconel. By choosing the 0.8mm corner radius, machinists benefit from a robust cutting edge that handles higher feed rates and deeper semi-finishing passes while delivering an exceptional surface Ra value.
Key Features
Specifically developed for high-temperature resistance and chemical stability in aerospace and marine alloys.
Positive rake design reduces cutting forces and eliminates tool pressure, preventing vibration on long workpieces.
A balance of strength and precision, perfect for semi-finishing and finishing with higher process security.

"The 0.8 radius is significantly tougher. Great for semi-finishing 316 parts without worrying about chipping."
— David H., USA"Perfekt für Edelstahl. Best chip control on the market for this price point."
— Hans G., Germany"Always reliable. TT9080 is our standard grade for all titanium valve work."
— Kenzo S., Japan"Ottima durata del tagliente su acciaio inossidabile 304."
— Pietro M., Italy"Superb finish and extremely fast delivery. Genuine TaeguTec quality."
— Chris L., UKFrequently Asked Questions
A: Yes. For optimal tool life in ISO M and ISO S materials, high-pressure coolant is highly recommended to control heat and evacuate chips.
A: For semi-finishing with the 08 radius and PC breaker, we recommend a depth of cut (Ap) between 0.3mm and 1.5mm.
A: No. TCMT inserts are 60° triangular shapes and require dedicated TCMT pockets. Standard CCMT holders use 80° rhombic pockets.
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.
