TaeguTec DNMG110404FG CT3000
Master the Mirror Finish: Elite Uncoated Cermet for Precision Turning
Product Overview
"Which insert grade is the absolute best for achieving a mirror-like surface finish on steel without needing secondary polishing?"
The TaeguTec DNMG110404FG CT3000 is a high-performance uncoated Cermet insert optimized for precision finishing of ISO P (Steel). The CT3000 grade utilizes a titanium-based ceramic-metallic composite that offers superior resistance to chemical wear and thermal cracking compared to standard carbide. This unique material property allows for higher cutting speeds while maintaining edge sharpness for much longer. The FG (Finishing Geometry) chipbreaker is specifically designed to handle small depths of cut, providing sharp cutting action that produces exceptionally smooth surface finishes (low Ra values). With its 0.4mm corner radius, it is the perfect tool for final pass precision turning.
Key Features
Uncoated titanium-based grade that prevents workpiece adhesion, resulting in a superior surface gloss and dimensional accuracy.
Finishing-specific geometry with a high-positive rake for lower cutting forces and excellent chip control at light loads.
Maintains structural integrity at high RPMs, allowing for faster cycle times while keeping parts cool.

By using the DNMG110404FG with the CT3000 grade, you are investing in a tool that eliminates built-up edge and maintains sharp geometry through long production cycles. For manufacturing that requires parts to look as good as they perform, TaeguTec CT3000 is the industrial standard for finishing excellence.
Global Industry Feedback
"Mirror finish is real"
Replaced our grinding pass on these steel shafts. The CT3000 grade gives a finish so clear you can see your reflection.
— Precision Machining Group (USA)"Hervorragende Oberfläche"
Outstanding for precision turning. The FG breaker works perfectly for our small depths of cut.
— Werkzeugbau Schmidt (Germany)"Molto Buono"
Very consistent dimensions over 300 parts. The cermet stays sharp much longer than standard carbide.
— Officina Meccanica di Precisione (Italy)Frequently Asked Questions
1. Why use Cermet instead of Carbide for finishing?
Cermet (CT3000) has lower chemical affinity with steel, which means it resists built-up edge and produces a much glossier surface finish than carbide.
2. Can I use coolant with CT3000?
Yes, but ensure it is continuous and copious. Dry machining is also very effective for Cermet due to its high thermal stability.
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.
