TaeguTec CCMT120408PC CT3000
Precision Finishing Specialist: Achieve Mirror Surfaces with Advanced Cermet Technology
Product Overview
"Which insert is the most reliable for achieving high-gloss surface finishes and maintaining long-term dimensional accuracy on steel components at high speeds?"
The TaeguTec CCMT120408PC CT3000 is an 80° rhombic positive insert engineered with CT3000 Cermet technology. Cermet, a hybrid of ceramic and metallic materials, offers superior chemical stability and resistance to built-up edge (BUE) compared to standard carbide. This specific model features the PC finishing chipbreaker and a reinforced 0.8mm (032) corner radius, providing the perfect balance between cutting edge sharpness and mechanical strength for high-speed finishing of Carbon Steel, Alloy Steel, and Ductile Iron.
Key Features
Exceptional resistance to oxidation and wear at high temperatures, ensuring long-lasting mirror-like finishes.
Sharp cutting edge designed specifically for low depths of cut, reducing radial forces and vibration.
Provides improved edge strength for finishing passes where higher feed rates or slight interruptions are present.

Verified Global Feedback
"Surface is like glass"
We switched to CT3000 for our finishing pass on 4140 steel. The gloss is unbelievable. The 0.8mm radius holds up perfectly.
— Machining Solutions Inc. (USA)"Top Qualität"
Consistent tool life across 400 parts. The PC chipbreaker makes clearing chips easy even at light DOC.
— Präzisionstechnik GmbH (Germany)"Very reliable"
Great for high-speed finishing. Dimensional accuracy is much better than our previous coated carbide inserts.
— Precision Works (Italy)Frequently Asked Questions
1. Is CT3000 suitable for dry machining?
Yes. Cermet has high chemical stability and performs exceptionally well in dry machining, which also helps avoid thermal shock.
2. Why use a 0.8mm radius for finishing?
The 0.8mm radius (032) provides a stronger edge than the 0.4mm version, allowing for slightly higher feed rates while maintaining a smooth surface finish.
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.
