ZCC.CT TNMG160404-DM YBC151
High-Speed Steel Finishing Carbide Inserts
Product Overview
"Which carbide insert is best for high-speed finishing and medium machining of carbon and alloy steels?"
The ZCC.CT TNMG160404-DM YBC151 is a double-sided triangular (60° hexagonal) insert engineered for ISO P (Steel) applications. By combining the YBC151 grade—featuring a thick Al2O3 CVD coating—with the -DM chipbreaker, this tool provides exceptional surface finishes and precise chip control during continuous to slightly interrupted cutting at high velocities.
Core Industrial Advantages
Superior Red Hardness
The thick CVD coating maintains cutting edge integrity even at extreme temperatures, allowing for high-speed machining (Vc).
-DM Geometry
Optimized for medium-duty machining. The unique chipbreaker design ensures smooth chip evacuation and prevents workpiece scratching.
6 Cutting Edges
Double-sided negative geometry provides maximum economy with 6 usable cutting edges per insert.

Professional Machinist Reviews
Exceptional Life
"Switched to YBC151 for our steel rollers. The tool life is double compared to our previous brand."
— Michael B., USA 🇺🇸Top Finish
"The -DM breaker leaves a mirror-like finish on alloy steel shafts. Saves us a secondary grinding step."
— Hans K., Germany 🇩🇪安定性が高い (High Stability)
"Consistently good results in high-speed CNC production. Very reliable inserts."
— Sato Y., Japan 🇯🇵Technical FAQ
Q: Is YBC151 better than YBC251 for finishing?
A: Yes. YBC151 has higher red hardness and wear resistance, making it superior for continuous high-speed finishing where heat resistance is key.
Q: What is the benefit of the -DM chipbreaker?
A: The -DM (Double Medium) geometry balances edge strength with chip-breaking capability, making it the "Goldilocks" choice for medium-duty machining.
Q: Can these be used on stainless steel?
A: While possible for limited ferritic stainless cuts, we recommend the YBM series for austenitic stainless steel 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.
