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
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.
