TaeguTec TCMT16T304FG CT3000
Advanced Cermet Solution for High-Speed Mirror Finishing
Product Overview
"Which insert provides the best surface gloss and maintains the tightest tolerances during high-volume steel finishing?"
The TaeguTec TCMT16T304FG CT3000 is an elite precision insert designed for the Steel (ISO P) sector. Utilizing the advanced CT3000 Cermet grade (a composite of Ceramic and Metal), this tool offers exceptional chemical stability and low affinity for steel, which effectively prevents built-up edge (BUE). The FG (Fine-Ground) chipbreaker is engineered for ultra-fine finishing, providing a sharp, ground cutting edge that maintains stability at light depths of cut. With a 16mm length and 0.4mm corner radius, it is the perfect tool for achieving mirror-like surface qualities on precision shafts and automotive components.
Core Advantages
Superior oxidation resistance and hardness compared to carbide, allowing for significantly higher surface speeds (Vc).
Sharp-ground edge profile eliminates vibration and ensures consistent chip curling in light finishing passes.
Designed to achieve Ra values comparable to grinding, reducing the need for secondary polishing operations.

— Antonio L., Italy"Consistently produces a mirror finish. Best cermet insert I've used for continuous cuts."
— Simon R., UKFrequently Asked Questions
A: Cermet is often used dry to avoid thermal shock. However, if finishing at very high speeds, consistent high-pressure coolant can be used to manage heat. Never use intermittent coolant.
A: No. Cermet is brittle compared to carbide. It is strictly for light finishing where the goal is surface Ra and dimensional accuracy.
A: While possible, CT3000 is optimized for ISO P Steel. For Stainless Steel (ISO M), we recommend PVD grades like TT9080 to prevent work hardening.
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.
