TaeguTec CCMT120404PC CT3000
Mastering the Mirror Finish: The Ultimate High-Speed Cermet Solution
Product Overview
"Which insert grade should I use to achieve a mirror-like Ra finish and maintain tight tolerances on steel parts during high-speed finishing operations?"
The TaeguTec CCMT120404PC CT3000 is a high-performance 80° rhombic insert crafted from CT3000 Cermet (Ceramic-Metallic). Unlike traditional carbide, Cermet provides superior chemical stability and resistance to built-up edge (BUE), making it indispensable for high-speed finishing of Carbon Steel, Alloy Steel, and ductile metals. The PC chipbreaker is precision-engineered for low depths of cut, ensuring exceptional chip evacuation and reduced cutting forces for a flawless, high-gloss surface finish.
Key Features
Exceptional heat and chemical resistance allows for ultra-high cutting speeds without edge degradation.
Designed specifically for precision finishing, reducing radial forces to eliminate tool chatter and vibration.
The non-welding properties of Cermet result in a superior surface Ra value compared to standard coated carbide.

Global Verified Feedback
"Flawless results"
We use CT3000 for our bearing housings. The surface finish is consistently under 0.8 Ra without any effort. Unbeatable for finishing.
— Precision Tooling Co. (Japan)"Top-Klasse Standzeit"
Amazing predictability on 1.0503 steel. We run this at 400 m/min and the tolerance holds for hundreds of parts.
— Metallfertigung GmbH (Germany)"Great for tight tolerances"
The PC chipbreaker really helps with chip control on small finishing passes. Very sharp and reliable.
— Advanced Machining (USA)Frequently Asked Questions
1. Should I use coolant with CT3000 Cermet?
Cermet performs best in dry machining or minimal lubrication (MQL) to prevent thermal cracking. If coolant is used, it must be high-pressure and consistent.
2. Can I use this for interrupted cuts?
Cermet is brittle compared to carbide. It is highly recommended for continuous cuts only. For heavy interruptions, use a coated 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.
