TaeguTec CCMT060204MT CT3000
Premium Cermet Grade for High-Speed Precision Finishing in Steel
Product Overview
"Which insert is best for achieving a mirror finish on steel components while maintaining tight dimensional tolerances at high cutting speeds?"
The TaeguTec CCMT060204MT CT3000 is an 80° rhombic turning insert engineered specifically for ISO P (Steel) finishing. Unlike traditional carbide, the CT3000 Cermet grade utilizes a titanium-based ceramic-metallic composite that provides exceptional chemical stability and resistance to built-up edge (BUE). The MT chipbreaker (Medium-Turning Geometry) offers a versatile chip control range, bridging the gap between light finishing and medium machining. This combination ensures that even at high speeds, the cutting edge remains sharp, delivering high-gloss surface finishes and consistent accuracy.
Key Features
High resistance to oxidation and wear, allowing for significantly higher cutting speeds than standard carbide.
Optimized for stable chip breaking across a wide range of feed rates in carbon and alloy steels.
Cermet's low affinity for steel prevents workpiece welding, resulting in superior Ra values and high-gloss parts.

Verified Global Feedback
"Like a mirror!"
Using CT3000 on low carbon steel shafts. The finish is so good we were able to skip the grinding step. Incredible savings.
— Precision Lathe Shop (USA)"Beste Oberflächenqualität"
High speed and no built-up edge. The MT chipbreaker is very stable even when the feed varies slightly.
— Fertigungstechnik AG (Germany)"Affidabile e Preciso"
Perfect for high-speed finishing. Dimensions stay true throughout the entire batch. Highly recommend for steel.
— Meccanica Italiana (Italy)Frequently Asked Questions
1. Can I use CT3000 for interrupted cuts?
Cermet is more brittle than carbide. For light interruptions, we recommend the PV3010 (PVD Coated) grade. CT3000 is best for continuous finishing.
2. Does this work on Stainless Steel?
While possible, cermet is optimized for ISO P (Steel). For stainless steel, we recommend our TT8125 PVD carbide grade.
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.
