TaeguTec TCMT16T304MT CT3000
Mastering Surface Perfection: High-Speed Cermet for Elite Steel Finishing
Product Overview
"Which insert is best for high-speed finishing to achieve a mirror surface on alloy steel parts?"
The TaeguTec TCMT16T304MT CT3000 is a high-tech 16mm triangular turning insert crafted from the advanced CT3000 Cermet grade. Cermet (Ceramic-Metal composite) provides exceptional chemical stability and resistance to oxidation at high temperatures, making it the ultimate choice for finishing Steel (ISO P). The MT (Medium Turning) chipbreaker is uniquely optimized for low cutting depths, ensuring sharp shearing action that prevents smearing and edge build-up. For manufacturers requiring high dimensional precision and superior aesthetic finishes, CT3000 delivers unparalleled results without the need for secondary grinding.
Core Advantages
The low affinity for steel prevents workpiece welding, resulting in superior Ra values and a brilliant finish.
CT3000 cermet maintains edge sharpness longer than traditional carbide during high-velocity continuous cutting.
Engineered for high-speed finishing, providing excellent chip control at light depths of cut (Ap).

"CT3000 is incredible. Our steel shafts come out with a mirror finish. No grinding needed."
— Michael B., Germany"Fast shipping to Michigan. The MT breaker is perfect for precision finishing of gear blanks."
— James W., USA"Excellent dimensional stability even in long finishing runs. Highly recommend for CNC lathes."
— Sato T., Japan"Ottima qualità superficiale su acciaio C45. Molto soddisfatto della durata."
— Giuseppe L., Italy"Switched from standard carbide to this cermet for our finishing passes. The difference is night and day."
— Chris P., USAFrequently Asked Questions
A: Cermet has excellent heat resistance. It is often recommended to run dry in continuous cuts to avoid thermal shock, though high-pressure coolant can be used if thermal stability is maintained.
A: Coated carbide is for bulk material removal and speed. CT3000 Cermet is for surface quality. Cermet does not weld to steel, preventing the 'dull' look often seen with carbide.
A: For finishing with a 0.4mm radius, keep the feed below 0.15 mm/rev to maintain the best surface Ra values.
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.
