TaeguTec TCMT090204PC TT9080
The Ultimate Stainless Steel Finisher: PVD Toughness meets PC Precision
Product Overview
"Which insert provides the best chip control and surface finish when machining gummy 304 or 316 stainless steel?"
The TaeguTec TCMT090204PC TT9080 is an industrial-grade 9mm triangular insert optimized for Stainless Steel (ISO M) and Superalloys (ISO S). The TT9080 grade utilizes a specialized sub-micron substrate with a physical vapor deposition (PVD) TiAlN coating, designed to resist thermal cracking and chemical wear. What sets this tool apart is the PC (Positive Finishing) chipbreaker, which features a high rake angle to shear through work-hardening materials like Inconel and 316L. This ensures low cutting forces, prevents Built-Up Edge (BUE), and delivers a superior surface Ra value during high-precision finishing operations.
Core Advantages
TT9080 is a universal grade for stainless steels and heat-resistant alloys, offering a perfect balance of hardness and toughness.
The PC chipbreaker is engineered for light depths of cut, curled chips tightly to prevent scratches on finished surfaces.
The 0.4mm corner radius reduces cutting pressure and vibrations, ideal for thin-walled parts and internal boring.

— Hiroshi N., Japan"Perfetto per acciaio inossidabile. Very reliable finishing grade."
— Marco T., Italy"Switched from a competitor to TaeguTec TT9080 and haven't looked back. 20% longer tool life."
— Steve L., USAFrequently Asked Questions
A: While the coating resists heat well, we strongly recommend using high-pressure coolant for stainless steel to prevent chip welding and ensure the PC breaker functions optimally.
A: The PC geometry is designed for finishing. We recommend staying between 0.2mm and 1.0mm for best results.
A: No, TCMT inserts require triangular holders with a 60-degree pocket. Please verify your toolholder designation before ordering.
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.
