TaeguTec TCMT16T304PC TT9080
Professional PVD Solution for Stainless Steel & Heat Resistant Alloys
Product Overview
"Which insert provides the cleanest chip control when finishing large-diameter stainless steel components?"
The TaeguTec TCMT16T304PC TT9080 is a high-performance 16mm triangular insert engineered specifically for Stainless Steel (ISO M) and Superalloys (ISO S). The TT9080 grade features a specialized sub-micron substrate paired with a high-aluminum content PVD coating, offering incredible resistance to thermal cracking and notch wear. The PC (Positive Finishing) chipbreaker is designed with a sharp rake angle and optimized land width to shear through work-hardening materials like 316L and Inconel with minimal cutting force. This combination ensures high dimensional accuracy and an exceptional surface finish even in gummy materials where chip welding is a constant threat.
Core Advantages
The TT9080 grade excels in resisting built-up edge (BUE) and oxidation, essential for high-temp alloy productivity.
The PC breaker is a finishing specialist, curling chips tightly for safe evacuation at light depths of cut.
The 0.4mm corner radius reduces tool pressure and vibration, delivering a mirror-like finish on precision bores.

"TT9080 is the gold standard for stainless. The finish is consistent part after part."
— Mark R., USA"Perfect chip control on my 316L job. The PC breaker is incredibly sharp."
— Stefan K., Germany"Best PVD insert we have used for Inconel. Fast shipping to Tokyo."
— Takashi O., Japan"Molto affidabile su acciai inossidabili. Ottima durata del tagliente."
— Lorenzo B., Italy"Original TaeguTec product. The tool life on Titanium is impressive."
— Kevin W., USAFrequently Asked Questions
A: While the PVD coating is heat resistant, for ISO M and ISO S materials, we always recommend high-pressure coolant to prevent built-up edge.
A: For finishing with the PC breaker, we recommend staying below 1.5mm to maintain chip control.
A: No. TCMT inserts are 60° triangles and require specific TCMT toolholders.
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.
