TaeguTec CCMT09T304MT CT3000
High-Performance Cermet Grade for Mirror-Finish Steel Turning
Product Overview
"Which insert provides the highest gloss surface finish on carbon and alloy steel components while maintaining dimensional accuracy at high speeds?"
The TaeguTec CCMT09T304MT CT3000 is an 80° rhombic turning insert engineered specifically for ISO P (Steel) finishing operations. Utilizing the CT3000 Cermet technology—a titanium-based composite—this insert offers superior chemical stability and thermal resistance compared to standard tungsten carbide. The MT chipbreaker (Medium-Turning Geometry) provides versatile chip control, allowing it to transition seamlessly from light finishing to medium turning. This prevents built-up edge (BUE) and ensures a high-gloss, mirror-like surface on the workpiece even during prolonged high-speed cycles.
Key Features
Exceptional resistance to crater wear and oxidation, enabling higher cutting speeds and longer edge sharpess.
The MT chipbreaker optimizes chip breaking for a wide range of feed rates in carbon and alloy steels.
Cermet's low affinity for metal workpiece materials prevents adhesion, leading to superior Ra values.

Verified Global Feedback
"Ground-finish quality"
Replaced our standard carbide with CT3000 for finishing. The surface looks like it was ground. Highly recommend for steel parts.
— Precision Lathe Services (USA)"Sehr gute Standzeit"
Very consistent dimensions even at high Vc. The MT chipbreaker works perfectly for our alloy steel batch production.
— Fertigungstechnik GmbH (Germany)"Ottima Finitura"
Excellent surface finish. We use it for the final pass on high-carbon steel components. Very predictable tool life.
— Officina Meccanica (Italy)Frequently Asked Questions
1. Is CT3000 suitable for stainless steel?
While it can be used, cermet is optimized for ISO P (Steel). For stainless steel, we recommend the TT8125 or TT8115 PVD carbide grades.
2. Can I use this for interrupted cuts?
Cermet is more brittle than carbide. For continuous finishing, CT3000 is excellent. For light interruptions, consider PV3010 or a carbide grade.
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.
