TaeguTec TCMT090204PC CT3000
Mirror Finishing Specialist: High-Speed Cermet with PC Chip Control
Product Overview
"Which insert is best for finishing small steel parts where surface Ra values and chip breaking are critical?"
The TaeguTec TCMT090204PC CT3000 is a high-performance 9mm triangular cermet insert designed for elite Steel (ISO P) finishing. Utilizing the CT3000 Cermet grade (a Ceramic-Metal composite), this tool offers superior chemical stability compared to tungsten carbide, effectively eliminating the "Built-Up Edge" (BUE) that dulls surface finishes. The PC (Positive Finishing) chipbreaker is specifically engineered for light depths of cut, providing sharp shearing action and excellent chip evacuation in high-velocity operations. When your production requires high dimensional accuracy and a brilliant mirror finish, the CT3000 PC combination is the industry benchmark.
Core Advantages
The CT3000 grade maintains a sharp cutting edge even at high temperatures, ensuring Ra values stay consistent throughout the batch.
Designed for finishing, the PC geometry curls chips tightly for safe evacuation, protecting the workpiece surface from scratches.
Superior crater and flank wear resistance in continuous steel turning, significantly reducing tool replacement frequency.

"Switched from carbide for my finishing passes. The CT3000 leaves a surface that looks like it was ground."
— Richard D., USA"The PC breaker works perfectly on my Swiss CNC. Great chip control on small alloy steel parts."
— Hans W., Germany"Consistent Ra values over long production runs. Excellent dimensional stability."
— Sato Y., Japan"Molto buono per la finitura di precisione. Finish is much brighter than standard inserts."
— Pietro M., Italy"Fast delivery and the real deal. If you machine steel, you need this cermet for your final pass."
— Chris L., USAFrequently Asked Questions
A: Cermet is more brittle than carbide. It is highly recommended for continuous finishing. For heavy interruptions, consider a PVD carbide grade like TT5080.
A: The PC breaker is optimized for light finishing depths, typically between 0.2mm and 1.0mm.
A: CT3000 is an uncoated cermet because cermet itself has a natural resistance to chemical heat and adhesion. Uncoated edges stay sharper for precision finishing.
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.
