TaeguTec CPMT080204FG CT3000
The Cermet Finishing Specialist: Achieve Mirror Surfaces in Steel Turning
Product Overview
"Which precision insert is best for achieving a high-gloss finish on steel parts while maintaining strict dimensional tolerances?"
The TaeguTec CPMT080204FG CT3000 is an elite turning solution engineered for ISO P (Steel) finishing. Utilizing the high-performance CT3000 Cermet grade, this insert provides superior chemical stability and resistance to built-up edge compared to standard carbide. The FG (Finishing-Ground) chipbreaker features a sharp, positive geometry that reduces cutting pressure, making it perfect for light depths of cut and high-speed finishing where surface integrity is critical.
Key Features
A titanium-based ceramic-metallic composite that maintains a sharp edge longer than carbide for high-speed finishing.
Designed for ultra-fine finishing. Ensures tight chip control even at low depths of cut (0.2mm - 1.0mm).
Low friction coefficients prevent material welding, resulting in exceptional Ra values and aesthetic surface quality.

Verified Global Feedback
"Mirror Finish on Steel"
Using the CT3000 on our CNC Swiss lathes has completely removed the need for secondary polishing. Ra values are consistently excellent.
— Precision Parts Inc (USA)"Edge Sharpness"
The FG breaker keeps the chips small and away from the workpiece. Essential for high-precision boring in alloy steels.
— Feinmechanik GmbH (Germany)"Consistent Quality"
Perfect for finishing small stainless and steel parts. Very stable at high RPMs.
— Techno Components (Japan)Frequently Asked Questions
1. Should I use coolant with CT3000 Cermet?
Cermet performs exceptionally well in dry conditions due to its high thermal stability. However, if used with coolant, ensure a consistent, high-volume flow to avoid thermal cracking.
2. What is the main advantage of FG breaker?
The FG (Finishing-Ground) chipbreaker is ground for high precision, offering a sharper edge and superior chip breaking at very light feeds and depths of cut.
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.
