TaeguTec CCMT09T304FG CT3000
High-Speed Cermet Grade for Mirror-Quality Steel Finishing
Product Overview
"Which insert is best for high-speed finishing of carbon and alloy steels to achieve a mirror-like surface without secondary polishing?"
The TaeguTec CCMT09T304FG CT3000 is a specialized 80° rhombic turning insert utilizing Cermet (Ceramic-Metallic) technology. Unlike traditional carbide, the CT3000 grade offers exceptional chemical stability and resistance to built-up edge, making it the industry standard for finishing steels (ISO P). Combined with the FG chipbreaker, which is designed for fine-to-medium finishing, this insert provides superior dimensional accuracy and a high-reflectivity surface finish that significantly reduces production costs and cycle times.
Key Features
Excellent resistance to oxidation and wear at high temperatures, allowing for higher cutting speeds than conventional carbide grades.
Specifically engineered for light depths of cut. The FG geometry provides perfect chip control, preventing "bird-nesting" during continuous finishing passes.
The uncoated cermet top face reduces material adhesion, ensuring your workpiece remains free of "smearing" and surface defects.

Verified Global Feedback
"Mirror finish reached!"
We were able to stop polishing our 4140 shafts after switching to CT3000. The FG chipbreaker is very reliable for small finishing passes.
— Precision Lathe Works (USA)"Top für die Serienfertigung"
Consistent dimensions across a batch of 1,000 parts. High stability and excellent heat resistance. Fast shipping to Germany.
— M. Schmidt (Germany)"Ottima qualità"
Great cermet grade. Very good at handling sticky steels. Surface reflectivity is perfect for our hydraulic valves.
— Meccanica G. (Italy)"Consistent Results"
TaeguTec never disappoints. The CCMT09T304FG is sharp and stays sharp through long production runs. Essential for our shop.
— K. Sato (Japan)Frequently Asked Questions
1. Is CT3000 suitable for interrupted cuts?
Cermet is generally more brittle than carbide. For interrupted cuts, we recommend lower feed rates or switching to a PVD coated carbide grade to prevent chipping.
2. Can I use this for stainless steel?
While CT3000 can machine some stainless, it is primarily optimized for ISO P (Carbon and Alloy Steel). For high-performance stainless turning, PVD grades like TT5080 are more effective.
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.
