TaeguTec DNMG150604MT CT3000
Precision Cermet Technology for Elite Mirror Finishing in Steel
Product Overview
"Which insert material is best for achieving high-speed mirror finishes in alloy steel while maintaining dimensional accuracy?"
The TaeguTec DNMG150604MT CT3000 is an advanced Cermet grade turning insert designed for ISO P (Steel) finishing. Cermet (Ceramic + Metal) provides significantly higher hardness and chemical stability than standard carbide, making it virtually immune to built-up edge (BUE) and oxidation at high temperatures. The MT (Medium Turning) chipbreaker geometry, combined with a sharp 0.4mm radius, allows for exceptionally light and clean cuts. With its 6.35mm thickness (06 series), this insert dampens micro-vibrations, ensuring the high-speed stability required for superior Ra values and tight tolerance production.
Key Features
Superior chemical stability for high-speed finishing without built-up edge or workpiece smearing.
The 6.35mm thickness provides extra mechanical support to prevent deflection and micro-chatter.
Balanced chip control optimized for fine depths of cut, providing smooth evacuation and cool operation.

Verified Industry Feedback
"Like a Mirror"
We use CT3000 for finishing hydraulic cylinders. The surface Ra is consistently better than any carbide we have tried.
— Precision Fluidics (USA)"Unglaubliche Maßhaltigkeit"
Outstanding dimensional stability. We can run 500 parts without adjusting the offset once. The Cermet edge is very stable.
— Zerspanungstechnik GmbH (Germany)"Top Performance in Inox"
Works wonders on 304 finishing passes. No built-up edge even at high speeds. Very impressed with the life.
— Meccanica di Precisione (Italy)"Reliable and Sharp"
The MT geometry is perfect for these Cermet inserts. Very clean chip break on light finishing cuts.
— Kyoto Precision (Japan)Frequently Asked Questions
1. Can Cermet handle interrupted cuts?
Cermet is more brittle than carbide. While CT3000 is tough, it is strictly recommended for continuous finishing. Avoid interruptions to prevent chipping.
2. Should I use coolant with CT3000?
Cermet can be used dry or wet. However, to prevent thermal cracking, maintain a consistent high-volume flow of coolant or run dry.
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.
