TaeguTec DCMT11T304MT CT3000
Elite Cermet Technology: Achieving Mirror-Like Surface Finishes in Steel
Product Overview
"Which insert grade is most effective for high-gloss finishing and semi-finishing in carbon and alloy steels without the need for secondary grinding?"
The TaeguTec DCMT11T304MT CT3000 is the ultimate solution for ISO P (Steel) precision turning. The CT3000 Cermet grade (Ceramic + Metal) provides significantly higher thermal stability than tungsten carbide, allowing it to withstand high cutting temperatures while resisting built-up edge (BUE). The MT (Medium-Turning) chipbreaker features a versatile geometry that bridges the gap between light finishing and semi-roughing, ensuring controlled chip breaking and preventing long, stringy chips that can damage the workpiece surface. With a 0.4mm corner radius, this insert provides the perfect balance of edge precision and toughness for intricate profile turning.
Key Features
A micro-grain cermet structure that offers incredible hardness and high-temperature chemical stability for a superior surface gloss.
Designed for semi-finishing applications, the MT breaker provides reliable chip control at moderate depths of cut and feed rates.
Cermet's low affinity for steel prevents workpiece welding, ensuring sub-micron surface Ra values and high dimensional accuracy.

Global Industry Feedback
"Eliminated Grinding"
The CT3000 cermet finish is so good we were able to eliminate the secondary grinding step on our shaft production. Incredible results.
— Precision Dynamics (USA)"Perfekte Oberfläche"
Super stable chip control with the MT breaker. The dimensions don't drift at all even after hundreds of parts.
— Werkzeug Technik (Germany)"Solid Cermet Performer"
Very clean cuts in alloy steel. The 0.4mm radius is perfect for fine detailing. Highly recommended for finish passes.
— Precisione Meccanica (Italy)Frequently Asked Questions
1. Is Cermet better than Carbide for all steel turning?
Cermet is superior for high-speed finishing because it resists chemical wear and heat better. However, for heavy roughing or interrupted cuts, Tungsten Carbide is tougher and more durable.
2. Can I use the MT breaker for light finishing?
Yes. The MT breaker is an all-rounder. While the FG is specifically for ultra-light finishing, the MT handles both finishing and semi-finishing with great stability.
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.
