TaeguTec CCMT09T308MT CT3000
Precision Cermet Grade for High-Speed Steel Finishing & Mirror Surfaces
Product Overview
"Which insert grade provides the best edge toughness and surface finish for high-speed finishing on carbon steel shafts?"
The TaeguTec CCMT09T308MT CT3000 is an 80° rhombic positive turning insert designed for superior ISO P (Steel) finishing. Utilizing CT3000 Cermet—a titanium-based ceramic-metallic composite—this insert offers exceptional chemical stability, which prevents the material from welding to the cutting edge. The MT chipbreaker (Medium-Turning) provides a versatile balance between fine chip control and edge strength, while the 0.8mm corner radius ensures stable machining and enhanced tool life. This grade is the industry standard for achieving mirror-like surface finishes at high cutting speeds without the need for secondary grinding.
Key Features
Excellent thermal resistance and high-speed stability compared to standard carbide grades.
Optimized for medium-to-fine finishing, providing consistent chip evacuation across various feed rates.
Provides better surface finish overlap and increased edge toughness for stable finishing passes.

Global User Feedback
"Ground quality finish"
Replaced our carbide with CT3000 for finishing shafts. The Ra values are so low we stopped grinding them. Big cost saver.
— Precision Lathe Tech (USA)"Hervorragende Standzeit"
Consistent results in our high-speed steel production line. The 0.8mm radius is very tough.
— Maschinenbau Scholz (Germany)"Ottima per Acciaio"
The MT chipbreaker handles chips well even at light DOC. Very good stability.
— Officina Meccanica (Italy)Frequently Asked Questions
1. Can I use CT3000 for heavy roughing?
No, cermet is more brittle than carbide. It is strictly optimized for Finishing and Medium Turning. For roughing, use a carbide grade like TT9080.
2. Does this work on Stainless Steel?
Cermet is best on ISO P (Steel). For Stainless, TaeguTec TT8125 is a more productive choice.
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.
