TaeguTec CCMT09T308FG CT3000
High-Speed Cermet Grade for Mirror-Quality Finishing of Steels
Product Overview
"Which insert is most suitable for high-speed finishing of carbon and alloy steels when I need to eliminate secondary polishing and achieve a mirror-like surface?"
The TaeguTec CCMT09T308FG CT3000 is an 80° rhombic turning insert utilizing advanced Cermet (Ceramic-Metallic) technology. The CT3000 grade is specifically engineered for finishing carbon and alloy steels (ISO P). Unlike traditional carbide, cermet offers exceptional chemical stability, which prevents workpiece material from "smearing" or welding to the tool edge. Combined with the FG chipbreaker—designed for precise chip control at light depths of cut—this insert ensures high dimensional accuracy and a superior reflective surface finish.
Key Features
Cermet's low affinity for steel results in significantly reduced built-up edge, producing a "mirror-like" finish that often eliminates the need for grinding.
The FG chipbreaker is optimized for finishing to medium-finishing, providing excellent chip breaking even at low feed rates and shallow cuts.
The 0.8mm radius (RE 08) provides a robust cutting edge that balances surface finish with increased edge strength for stable production.

Verified Global Feedback
"Stunning surface finish"
Using these on 4140 steel shafts. The mirror finish is so good we were able to skip the grinding process. Very reliable chip control with the FG breaker.
— Precision Lathe Shop (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)"Great for Alloy Steels"
Cermet CT3000 is my go-to for final finishing. The 0.8mm radius gives a very stable edge and the finish is excellent for our hydraulic components.
— Meccanica G. (Italy)"High Dimensional Stability"
The repeatability between inserts is perfect. We achieve mirror finishes on CNC lathes at much higher speeds than carbide.
— K. Sato (Japan)Frequently Asked Questions
1. Can I use Cermet for interrupted cuts?
Cermet is more brittle than carbide. While it can handle very light interruptions, it is primarily designed for continuous finishing. For heavy interruptions, use a PVD-coated carbide grade.
2. Is coolant required for CT3000?
Cermet can be used for dry machining due to its thermal stability. However, a stable flow of coolant can help with chip evacuation and maintaining consistent part dimensions in large 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.
