TaeguTec DNMG150404R-VF CT3000
Mirror Finish Precision: The Cermet Professional Choice for Steel Finishing
Product Overview
"Which insert grade is most effective for achieving a high-gloss surface finish on steel while maintaining extreme dimensional accuracy?"
The TaeguTec DNMG150404R-VF CT3000 is a high-performance Cermet (Ceramic-Metallic) insert designed for finishing operations. The CT3000 grade offers superior oxidation resistance and lower affinity to workpiece materials compared to standard carbide, effectively eliminating built-up edge (BUE). Paired with the VF (Very Fine) chipbreaker, this insert excels at high cutting speeds and low feed rates, delivering exceptional chip breaking even at extremely shallow depths of cut. This is the ultimate tool for CNC operators requiring precision tolerances and high-quality aesthetic finishes.
Key Features
Uncoated cermet provides high hardness and chemical stability for superior surface integrity and long edge life.
The Very Fine chipbreaker is optimized for light finishing passes, ensuring stable chip evacuation.
Maintains sharp cutting edges longer than carbide in finishing, reducing the need for frequent offsets.

Verified Global Feedback
"Stunning Surface Finish"
We use CT3000 for finishing valve stems. The surface is so smooth we've been able to eliminate the grinding stage. Truly impressive.
— Precision Components (USA)"Sehr Präzise"
Outstanding dimensional stability. The VF chipbreaker works perfectly at 0.1mm depth of cut. Very consistent results.
— Schmidt Feinmechanik (Germany)"Finitura a Specchio"
The cermet grade is fantastic. No built-up edge even on softer steels. Surface finish is like a mirror.
— Officina Meccanica Rossi (Italy)"Excellent Performance"
Great tool life at high RPM. The R-VF geometry is very sharp and reliable for finishing passes.
— Tanaka Manufacturing (Japan)Frequently Asked Questions
1. Can I use CT3000 for roughing?
No. Cermet is brittle compared to carbide. CT3000 is strictly for finishing passes with light depths of cut and high speeds.
2. Does this insert require coolant?
Cermet can be used dry or wet. However, for the best surface finish and to prevent thermal shock, consistent coolant flow or dry cutting is recommended over intermittent cooling.

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.
