TaeguTec TNMG 160408 MT CT3000
Professional High-Speed Cermet Insert for Superior Surface Finishing
Product Overview
"Which turning insert provides the best surface finish on steel while maintaining edge strength for semi-finishing cycles?"
The TaeguTec TNMG 160408 MT CT3000 is a high-performance Cermet insert engineered for CNC professionals who refuse to compromise on surface aesthetics. Unlike standard carbide, the CT3000 grade (Ceramic + Metal) offers exceptional chemical stability, effectively preventing the Built-Up Edge (BUE) that ruins surface Ra values. The MT Chipbreaker and 0.8mm radius provide the perfect geometry for stable chip evacuation in medium-to-finish turning applications on ISO P (Carbon/Alloy Steel). Use this insert to achieve a "mirror finish" and eliminate the need for costly secondary grinding.
Core Performance Features
Superior resistance to oxidation and crater wear, optimized for ultra-high cutting speeds in finishing.
Enhanced edge strength (08) for higher feed rates without sacrificing the legendary Cermet finish.
Triangular negative geometry providing 6 stable cutting edges for maximum ROI per part.

Applications & Compatibility
- Final Finishing: Critical for automotive and aerospace components requiring aesthetic gloss.
- Semi-Finishing: The 0.8mm radius allows for higher feed rates in cleaning up pre-roughed parts.
- Continuous Turning: Best used in stable, continuous cuts on carbon, alloy, and tool steels.
- Compatibility: Standard ISO/ANSI sizing fits all major brand 16-size TNMG toolholders.

Machinist Feedback
"Switched from carbide to CT3000 for our steel gear finishing. The Ra value is perfect."
— Robert K., USA"Beste Oberflächengüte, die wir je hatten. CT3000 hält die Toleranz über lange Serien."
— Hans G., Germany"Eccellente finitura superficiale. Risparmiamo tempo eliminando la lucidatura."
— Paolo V., Italy"Very consistent performance at 300m/min. Great for mass production finishing."
— Tanaka S., JapanFrequently Asked Questions
A: Cermet is brittle. It is highly recommended for continuous cuts only. For interruptions, use a carbide grade like TT8125.
A: Cermet works best dry or with high-pressure constant coolant. Avoid intermittent coolant as it causes thermal cracking.
A: For finishing, we recommend an Ap between 0.2mm and 1.5mm for the 0.8 radius.
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.
