ZCC.CT RCKT2006MO-DM YBC401 Milling Insert
The Ultimate Roughing Powerhouse for Large-Scale Steel Components
Product Overview
The ZCC.CT RCKT2006MO-DM in YBC401 grade represents the peak of material removal capacity. Designed for ISO P30-P50 steel milling, this insert thrives in the most unstable and demanding environments. The YBC401 grade combines a high-toughness substrate with a thick CVD coating, specifically engineered to resist thermal shock and impact. The DM (Medium-Roughing) chipbreaker features a refined edge land that balances sharpness with structural strength, making it perfect for high-feed copy milling and face milling on large forged or cast steel parts.
Key Core Advantages
- [!] Extreme Impact Resistance: Optimized for heavy interrupted cuts where conventional grades chip or fracture.
- [!] Massive 20mm Profile: The RCKT2006 size provides unmatched edge strength and allows for high depths of cut (Ap) in heavy roughing.
- [!] Advanced CVD Multi-Layer Coating: Thick Al2O3 layer ensures superior heat resistance during dry machining at high loads.

Why Machinists Choose ZCC.CT
"The RCKT 20mm is a beast. YBC401 handles the impact of large forged steel blocks without any edge chipping."
— David R., USA 🇺🇸"Sehr zuverlässig. Die Standzeit bei unterbrochenem Schnitt ist beeindruckend."
— Klaus L., Germany 🇩🇪"Ottima resistenza agli urti. La geometria DM scarica bene il truciolo anche a profondità elevate."
— Marco F., Italy 🇮🇹"Consistent quality every time. Best performance-to-cost ratio for our large mold shop."
— Tanaka S., Japan 🇯🇵FAQ
Q: What is the main advantage of the YBC401 grade?
A: It is ZCC.CT's toughest CVD grade for steel milling, designed specifically to prevent fracture in heavy interrupted cuts and rough surfaces.
Q: Can I use this for stainless steel?
A: While it can cut some steel-like stainless, for optimized productivity, we recommend the YBM series specifically for M-class materials.
Q: Why choose the DM chipbreaker for 20mm inserts?
A: The DM chipbreaker provides a stable cutting edge that handles the high torque of a 20mm insert while ensuring excellent chip evacuation in roughing.
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.
