Premium Uncoated Cermet: The Secret to Mirror-Like Surface Finishes
Product Overview
"Which insert grade is best for achieving a high-gloss finish on carbon steel while maintaining zero built-up edge at high speeds?"
The TaeguTec DCMT11T304PC CT3000 is a high-performance Cermet (Ceramic-Metallic) insert designed for precision ISO P (Steel) finishing. The CT3000 grade is an uncoated cermet that provides incredible resistance to oxidation and chemical wear, allowing it to maintain a sharp edge much longer than carbide during high-velocity finishing. The PC (Precision-Chip) chipbreaker is engineered for light depths of cut, featuring a sharp geometry that minimizes cutting forces and prevents workpiece vibration. With a 0.4mm corner radius, this insert is optimized for tight tolerances and elite Ra values.
Key Features
Uncoated cermet composition offering high hardness and superior thermal stability for high-speed finish turning.
Designed for high-precision finishing, providing clean chip breaking at low feed rates and shallow depths.
The chemical inertness of the cermet prevents the "Built-Up Edge" phenomenon, ensuring a smooth, mirror-like gloss.

Global Industry Feedback
"Like a Mirror"
Achievement of surface finish Ra 0.4 on 1018 steel was effortless with CT3000. Best cermet we've used.
— Precision Dynamics (USA)"Hervorragendes Finish"
Perfect for our automotive gears. The PC breaker controls the chip perfectly even at very low feeds.
— AutoTech GmbH (Germany)"Extremely Consistent"
Very stable dimensions over a 500-piece run. No thermal cracking at high speeds.
— Meccanica Precisione (Italy)Frequently Asked Questions
1. Should I use coolant with CT3000 cermet?
Cermets can be used dry or with coolant. However, if using coolant, ensure a constant and high-volume flow to prevent thermal shock.
2. Can I use this for interrupted cuts?
Cermet is brittle compared to carbide. It is recommended for stable, continuous finishing cuts. For heavy interruptions, use a carbide grade like TT8125.
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.
