TaeguTec TDXU 4E-0.4 CT3000
Precision 4.0mm Cermet Solution for Mirror-Finish Steel Machining
Product Overview
"Which 4mm insert is best for achieving a mirror surface finish at high speeds in carbon steel profiling?"
The TaeguTec TDXU 4E-0.4 CT3000 is a specialized multi-directional insert designed for precision finishing. Utilizing a CT3000 Cermet (Ceramic-Metallic) substrate, this insert offers superior chemical stability and resistance to built-up edge compared to traditional carbide. The XU chipbreaker geometry is optimized for the unique flow of cermet, ensuring excellent chip control during both radial grooving and axial turning. With a 4.0mm width and a 0.4mm corner radius, it is the ideal tool for CNC operators who demand high-speed performance and tight dimensional tolerances in Steel (ISO P) applications.
Core Advantages
Uncoated cermet grade providing extreme hardness and low affinity for workpiece material, resulting in exceptional surface finishes.
Seamlessly switch from plunging to longitudinal turning. Perfect for complex profiling without tool change interruptions.
Superior resistance to oxidation and crater wear at high temperatures, ensuring long-term edge sharpness.

Why Machinists Choose CT3000
The TDXU 4E-0.4 CT3000 eliminates the need for secondary grinding in many steel applications. By utilizing cermet technology, you can achieve Ra values that standard carbide simply cannot reach, all while maintaining high production speeds.
"Surface finish is incredible. We achieve a mirror shine on 1045 steel without a grinder. CT3000 is top tier."
— Alan P., USA"Hervorragende Oberflächengüte bei hohen Geschwindigkeiten. Der XU-Spanbrecher ist sehr stabil."
— Bernd L., Germany"Finitura superficiale perfetta su acciai legati. Riduce significativamente i tempi di produzione."
— Fabio R., Italy"Excellent chemical stability. No built-up edge even after hours of high-speed turning."
— Kenji S., JapanFrequently Asked Questions
A: Cermet is more brittle than carbide. For light interruptions, it works well, but for heavy interrupted cuts, we recommend the TT9080 grade.
A: Cermet can often be run dry to avoid thermal shock, but if using coolant, ensure it is high-pressure and consistent to maintain tool life.
A: As a finishing insert, we recommend a depth of cut (Ap) between 0.2mm and 1.2mm for optimal results.

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.
