TaeguTec CCMT060204FG CT3000
Premium Cermet Grade for High-Speed Mirror Finishing of Steels
Product Overview
"Which turning insert should I choose to eliminate secondary polishing and achieve a reflective surface on steel parts?"
The TaeguTec CCMT060204FG CT3000 is a specialized Cermet (Ceramic-Metallic) insert designed for high-precision finishing of carbon and alloy steels (ISO P10-P20). Unlike standard carbide, the CT3000 grade offers superior chemical stability, which prevents workpiece material from welding to the tool. Combined with the FG chipbreaker—engineered for light depths of cut and smooth chip evacuation—this insert delivers the "Mirror Finish" required in high-end mechanical components and automotive finishing.
Key Features
The uncoated cermet grade provides a sharp, low-friction cutting edge that reduces heat and eliminates "smearing" on the workpiece.
Optimized for light depths of cut (0.5mm - 1.5mm), the FG chipbreaker ensures excellent chip control even at low feed rates.
Maintains hardness at higher cutting speeds compared to carbide, allowing for increased productivity in CNC lathe operations.

Verified Global Feedback
"Flawless surface finish"
We use these on 1045 steel shafts. The mirror finish is so good we were able to cut out the grinding step entirely. High ROI.
— Precision Lathe Shop (USA)"Top für Serienfertigung"
Very stable dimensions across large batches. The FG chipbreaker controls chips perfectly at high speeds. Fast shipping to Germany.
— K. Wagner (Germany)"Ottima qualità"
Great cermet grade. Very little built-up edge even after hours of turning alloy steel parts. Reliable performance.
— Meccanica G. (Italy)"Consistent Finishing"
CT3000 is our go-to for final finishing passes. The repeatability between inserts is excellent. 100% satisfied.
— T. Sato (Japan)Frequently Asked Questions
1. Can I use Cermet for roughing operations?
No. Cermet is more brittle than carbide and is specifically designed for finishing passes with light depths of cut. For roughing, we recommend CVD carbide grades like TT8125.
2. Is coolant required for the CT3000 grade?
While cermet can be used for dry machining due to its thermal stability, a stable flow of coolant can help with chip evacuation and maintain consistent dimensions in large production runs.
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.
