TaeguTec DCMT070202FA CT3000
Thermal Stability Meets Surface Excellence: The High-Speed Cermet Solution
Product Overview
"Which insert is best for high-speed finishing of steel parts where a long tool life and high-gloss surface finish are critical?"
The TaeguTec DCMT070202FA CT3000 is an elite precision turning insert engineered for ISO P (Steel) and ISO M (Stainless Steel) finishing. Crafted from the CT3000 Cermet grade, this insert combines the hardness of ceramic with the toughness of metal, offering incredible resistance to crater wear and plastic deformation at high cutting temperatures. The FA (Finishing-Automotive) chipbreaker is specifically designed with a sharp cutting edge and narrow groove geometry to ensure excellent chip control at light depths of cut, resulting in a superior surface Ra value.
Key Features
Advanced TiCN-based cermet provides high chemical stability and superior resistance to built-up edge (BUE).
Sharp geometry designed for light finishing cycles, providing smooth chip evacuation and reducing vibration.
Maintains edge hardness at elevated speeds, making it ideal for high-speed dry or wet machining.

Compatible Toolholders
This 07-size DCMT insert is designed for standard holders like SDJCR/L 07, SDNCN 07, and S-SDUCR/L 07 boring bars.
Product Applications
- High-precision finishing of automotive engine parts and valve components.
- Mirror-finish profile turning of stainless steel medical instruments.
- Continuous high-speed finishing of small carbon steel shafts and gears.
- Excellent for finishing applications where dimensional accuracy and surface quality are paramount.
Compatibility & Equipment
The DCMT0702 geometry is compatible with all standard ISO turning holders using a screw-on clamping system. It is ideal for use on high-precision CNC lathes, Swiss-type automatic lathes, and multitask machining centers where high RPM stability is required.
TaeguTec Grade Comparison (Finishing)
| Grade Name | Material Composition | Advantage |
|---|---|---|
| CT3000 (Cermet) | TiCN + Metal Binder | Surface Finish: Best for high-gloss, high-speed steel finishing. |
| PV3010 (Coated Cermet) | PVD Coated Cermet | Tool Life: Added wear resistance for tougher alloys. |

When precision isn't just a requirement, but a signature, industry leaders trust TaeguTec.
Verified Global Feedback
"Stunning Surface Finish"
We switched to the CT3000 for our steel transmission shafts. The Ra finish is incredible; we've completely skipped the finishing grind step.
— Precision Component Mfg (USA)"Perfect for Swiss Lathes"
The 0.2mm radius and FA breaker are perfect for our small stainless parts. No burrs and very consistent sizes over long shifts.
— Med-Tech GmbH (Germany)"High Speed Stability"
Very stable performance even when we push the RPM. The cermet grade handles heat much better than our previous coated carbide.
— G-Industrial KK (Japan)Frequently Asked Questions
1. What is the main benefit of Cermet over Carbide?
Cermet has higher chemical stability and thermal resistance, which prevents the material from sticking to the edge (BUE), leading to a much better surface finish on steel.
2. Can I use this for heavy roughing?
No. Cermet is more brittle than carbide. It is specifically designed for finishing and semi-finishing at light depths of cut. For roughing, we recommend TaeguTec's TT8125 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.
