TaeguTec DCMT11T302FA CT3000
The Pinnacle of Surface Quality: High-Speed Cermet Solution for Mirror Finishing
Product Overview
"Which precision insert should I use to achieve a mirror-like Ra finish on steel parts without frequent tool changes at high speeds?"
The TaeguTec DCMT11T302FA CT3000 is an elite turning insert engineered for the final finishing stages of ISO P (Steel) and ISO M (Stainless Steel) components. Unlike standard carbide, the CT3000 Cermet grade utilizes a titanium-based ceramic-metal composite that resists oxidation and material welding (BUE) even at extreme cutting temperatures. The FA (Finishing-Automotive) chipbreaker is ground to perfection, providing a sharp cutting edge and narrow groove geometry that guarantees stable chip evacuation during light-depth finishing, even in gummy materials.
Key Features
A TiCN-based cermet that provides incredible chemical stability, ensuring the insert edge stays sharp and avoids sticking.
Peripheral ground geometry provides a razor-sharp cut, drastically reducing tool pressure and preventing work-hardening.
Maintains hardness at high Vc (Cutting Speeds), allowing for faster cycle times without compromising surface integrity.

Compatible Toolholders
This 11-size DCMT insert is designed for standard holders like SDJCR/L 11, SDNCN 11, and S-SDUCR/L 11 boring bars.
Product Applications
- High-precision finishing of automotive crankshafts and small engine parts.
- Mirror-finish profile turning for medical-grade stainless steel components.
- Final pass machining for aerospace alloy steel fasteners and fittings.
- Excellent for Swiss-type lathes and small part turning where surface Ra is critical.
Compatibility & Equipment
The DCMT11T3 geometry is a universal standard. It is compatible with all screw-on ISO turning holders. Best performance is observed on CNC lathes with high-spindle speeds, allowing the CT3000 grade to reach its optimal thermal efficiency range.
TaeguTec Grade Comparison (Finishing)
| Grade Name | Substrate | Primary Focus |
|---|---|---|
| CT3000 (Cermet) | TiCN Cermet | Precision Ra: Best for high-gloss finishing of steel. |
| PV3010 (PVD Cermet) | Coated Cermet | Durability: Extended tool life in intermittent cuts. |
Why Choose TaeguTec?
TaeguTec, as an IMC Group brand, is a global leader in high-performance tooling. The CT3000 Cermet series represents our commitment to "Green Machining"—achieving surface finishes so perfect that secondary grinding processes can often be eliminated entirely. Unlike carbide, our cermet maintains a chemical inertness that prevents the atomic bonding of steel to the insert tip, ensuring your last part is as dimensionally perfect as the first. Choose TaeguTec for precision that defines your workshop.
Verified Global Feedback
"Mirror finish reached!"
We use these on alloy steel 4140. The Ra finish is better than we ever got with coated carbide. Saved us a grinding step.
— Precision Works (USA)"Exzellente Standzeit"
Great life at high speed. The FA chipbreaker works perfectly on light finishing cuts. No stringy chips.
— Mech-Fertigung GmbH (Germany)"Stable Precision"
Dimensions stay consistent throughout the shift. Cermet handles the heat very well during dry machining.
— K-Industry (Japan)Frequently Asked Questions
1. Why is cermet better for steel finishing than carbide?
Cermet (Ceramic-Metal) has a low affinity for steel, meaning the work material won't stick to the tool. This prevents Built-Up Edge (BUE) and results in a much smoother surface finish.
2. Can I use these for Aluminum?
No. For aluminum, we recommend uncoated sharp carbide (like TaeguTec K10). Cermet is optimized for ferrous materials like steel and stainless steel.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
