ZCC.CT RCKT1606MO-DM YBC401 Round Milling Insert
Heavy-Duty Roughing Solution for Interrupted Steel Machining
Product Overview
The ZCC.CT RCKT1606MO-DM in YBC401 grade is a powerhouse for large-scale milling. Designed for the ISO P30-P50 range, this insert excels in tough conditions where edge security is paramount. The DM (Medium-Roughing) chipbreaker provides a reinforced edge that prevents micro-chipping, while the round geometry ensures maximum strength during high-load 3D profiling. The YBC401 grade features a thick, wear-resistant CVD coating over a high-toughness carbide substrate, making it the go-to choice for forged steel and heavy steel castings.
Core Technical Advantages
- [✓] Extreme Edge Security: The YBC401 grade is ZCC.CT's toughest CVD solution, specifically formulated to resist impact in interrupted cuts.
- [✓] Optimized DM Chipbreaker: The "DM" geometry balances sharpness with landing strength, ensuring smooth chip evacuation during heavy profiling.
- [✓] Extended Tool Life: Thick Al2O3 CVD coating provides a superior thermal barrier for high-heat steel machining.

Machinist Reviews
"The YBC401 is incredible for roughing large forged steel parts. No vibration, pure security."
— Robert D., USA 🇺🇸"Sehr gute Wendeplatte für schwere Bearbeitung. Hält den Schnitt auch bei Unterbrechungen."
— Hans W., Germany 🇩🇪"Ottimo prodotto per sgrossatura. Il truciolo si rompe bene anche con avanzamenti elevati."
— Luca P., Italy 🇮🇹"Reliable tool life in the most difficult steel castings. Highly recommend ZCC-CT."
— Tanaka Y., Japan 🇯🇵Frequently Asked Questions
Q: Is this insert suitable for dry machining?
A: Yes, the CVD coating on YBC401 provides excellent thermal protection, making it very effective for dry roughing in steel.
Q: What makes the DM chipbreaker special?
A: DM stands for Medium-Roughing. It has a reinforced land to handle high feed rates without sacrificing the smoothness of copy milling.
Q: Can I use this for stainless steel?
A: While it can handle some steel-like stainless, we recommend the YBM series for dedicated stainless steel machining to avoid 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.
