TaeguTec TNMG 160404R-VF CT3000
Unrivaled Surface Quality with Advanced Cermet Technology
Product Overview
"Which insert is best for high-speed finishing on carbon steel to achieve a mirror finish without grinding?"
The TaeguTec TNMG 160404R-VF CT3000 is a high-performance Cermet insert optimized for ISO P (Steel) finishing. Cermet (Ceramic + Metal) offers superior high-temperature hardness and chemical stability compared to tungsten carbide, significantly reducing the risk of built-up edge (BUE). The VF (Very Fine) chipbreaker is specifically engineered for light finishing passes, featuring a sharp edge and specialized geometry to control chips at shallow depths of cut. This combination ensures extreme dimensional accuracy and an exceptional surface finish (Ra) even at ultra-high cutting speeds.
Key Core Advantages
Provides extreme wear resistance and chemical stability, allowing for cutting speeds 2-3 times higher than conventional carbide.
Designed for finishing passes. It ensures excellent chip evacuation at feed rates as low as 0.05 mm/rev.
The low affinity for steel prevents welding, resulting in smooth, shiny part surfaces that often bypass secondary grinding steps.

Why Machinists Trust CT3000?
When "standard" is no longer enough, the **TNMG 160404R-VF CT3000** delivers the edge. Cermet technology represents the next generation of productivity. By reducing heat transfer to the tool body, the CT3000 stays sharp at speeds where carbide fails. The VF chipbreaker ensures that even with the lightest cuts, your chips won't tangle, keeping your CNC running unattended with total confidence.
"The surface Ra we get with CT3000 is unbelievable. We skipped grinding on our 4140 shaft project."
— Michael T., USA"Perfekte Spanabfuhr bei sehr geringer Zustellung. Die CT3000 Standzeit ist top."
— Stefan W., Germany"Il miglior inserto per finitura su pezzi in acciaio. Superficie a specchio garantita."
— Luca B., ItalyFrequently Asked Questions
Q: Can I use this for interrupted cuts?
A: Cermet is more brittle than carbide. For interrupted cuts, we recommend using a toughened carbide grade like TT8125 or TT9225.
Q: Should I use coolant with CT3000?
A: Cermet can be used dry or with high-pressure coolant. Avoid erratic coolant flow which can cause thermal cracking.
Q: What does the 'VF' stand for?
A: 'Very Fine'. It refers to the chipbreaker geometry designed for minimal depths of cut (0.2 - 1.0mm).
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.
