TaeguTec DCMT11T308MT CT3000
Precision Cermet Technology: Achieving Superior Surface Quality in Steel Alloys
Product Overview
"Which insert grade provides the best balance of edge toughness and high-gloss finish for semi-finishing steel parts?"
The TaeguTec DCMT11T308MT CT3000 is a high-performance cermet solution designed for ISO P (Steel) applications. By utilizing a composite of ceramic and metal, the CT3000 grade offers higher hardness at red-heat temperatures than traditional tungsten carbide. The MT (Medium-Turning) chipbreaker is engineered for reliability, offering a stabilized cutting edge that prevents micro-chipping while ensuring effective chip fragmentation. With its 0.8mm corner radius, this insert provides enhanced edge strength, making it the perfect choice for semi-finishing passes where surface integrity and tool longevity are paramount.
Key Features
Excellent resistance to chemical wear and oxidation. Perfect for high-speed finishing where aesthetic gloss is required.
A reinforced chipbreaker designed to handle a wider range of feed rates while maintaining stable chip flow.
Provides a robust cutting edge that allows for higher feed rates compared to 0.4mm variants without sacrificing finish quality.

Global Industry Feedback
"Stunning Surface Quality"
We use CT3000 for finishing our carbon steel shafts. The mirror finish is so consistent it saved us a secondary polishing step.
— Precision Components Inc. (USA)"Top für die Serienfertigung"
The MT chipbreaker is very stable. Excellent dimensional control over 500+ piece batches.
— Maschinenbau Scholz (Germany)"Ottimo inserto cermet"
High-speed performance is excellent. Very little built-up edge even in gummy steel alloys.
— Meccanica di Precisione (Italy)Frequently Asked Questions
1. What is the difference between CT3000 and carbide?
Cermet (CT3000) is harder and more chemically stable at high speeds than carbide. This allows for higher surface gloss but makes it more sensitive to heavy interruptions.
2. Can I use the MT breaker for roughing?
No. The MT breaker is designed for semi-finishing and finishing. For roughing, a specialized carbide grade with a heavier geometry is recommended.
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.
