TaeguTec DCMT11T308PC CT3000
High-Gloss Cermet Excellence: Engineered for High-Speed Precision Finishing
Product Overview
"Which insert grade is most effective for achieving a mirror-like gloss on alloy steel parts while maintaining high edge sharpness?"
The TaeguTec DCMT11T308PC CT3000 is a specialized Cermet (Ceramic-Metallic) turning insert designed for high-precision ISO P (Steel) finishing. The CT3000 grade offers incredible thermal and chemical stability, which prevents the "Built-Up Edge" (BUE) common in traditional carbide inserts. The PC (Precision-Chip) chipbreaker is optimized for small depths of cut, featuring a sharp cutting edge that minimizes tool pressure and workpiece deflection. With a 0.8mm corner radius, this insert provides enhanced edge strength for stable high-speed finishing across a variety of steel components.
Key Features
A specialized ceramic-metallic substrate that maintains a razor-sharp edge and resists oxidation at extreme cutting temperatures.
Sharp geometry designed for precision finishing, ensuring perfect chip fragments at light feed rates to prevent surface scratches.
Exceptional chemical stability ensures zero chemical reaction with the workpiece, resulting in superior Ra values.

Global Industry Feedback
"Perfect Ra Results"
Achievement of a mirror finish on 1045 steel was effortless. Tool life is much longer than standard carbide at high speeds.
— Precision Machining Co. (USA)"Keine Aufbauschneide"
Zero built-up edge issues. The PC chipbreaker works perfectly for our precision finishing passes.
— Müller CNC-Technik (Germany)"Consistent Quality"
Holds dimensions across 500+ parts with no significant wear. Highly recommended for automotive shafts.
— Meccanica S.r.l (Italy)Frequently Asked Questions
1. Should I use coolant with CT3000 cermet?
Cermets can be used dry or with coolant. If using coolant, ensure a constant and high-volume flow to avoid thermal shock/cracking.
2. How does CT3000 compare to carbide?
CT3000 (Cermet) offers higher chemical stability and heat resistance, making it superior for high-speed finishing where gloss is required.
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.
