TaeguTec DCMT070204FG CT3000
Master of Mirror Finishes: High-Speed Uncoated Cermet for Precision Turning
Product Overview
"Which cermet insert is best for achieving a mirror Ra finish on carbon steel at high cutting speeds?"
The TaeguTec DCMT070204FG CT3000 is a high-performance finishing specialist designed for ISO P (Steel) and ISO K (Cast Iron). The CT3000 grade is an uncoated cermet, which boasts a high resistance to oxidation and a low affinity for workpiece materials, virtually eliminating built-up edge (BUE). The FG (Finishing-General) chipbreaker features a Sharp-Edge design that excels in light-duty finishing, providing consistent chip evacuation and superior surface integrity. With a 0.4mm (1/64") radius, it strikes the ideal balance between edge strength and precision detail.
Key Features
A TiCN-based cermet that maintains edge sharpness longer than carbide in high-speed finishing environments.
Specifically engineered for small depths of cut, ensuring smooth chip flow and preventing surface scratching.
The uncoated surface reduces friction and thermal deformation, ensuring micron-level dimensional accuracy.

Global Industry Feedback
"Eliminated Secondary Polishing"
Using CT3000 on 1045 steel. The finish is so bright we skipped the polishing step. Incredible Ra values.
— Precision Dynamics (USA)"Top für kleine Bohrungen"
Great for small boring bars. Chip control is very stable even at 0.1mm DOC.
— Zerspanung GmbH (Germany)"Consistent in Cast Iron"
Excellent dimensional stability. Dimensions stay consistent across 500+ parts.
— Moto-Tech (Italy)Frequently Asked Questions
1. Should I use coolant with CT3000 cermet?
Cermet can be used dry or wet. However, for the best surface finish and to prevent thermal shock, high-pressure continuous coolant or MQL is recommended.
2. Is the FG breaker suitable for roughing?
No. The FG chipbreaker is optimized for finishing cycles (DOC < 1.0mm). For heavier cuts, look for the TaeguTec MT or PC chipbreakers.

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.
