ZCC.CT RCKT1606MO-DR YBC401 Milling Insert
Engineered for Maximum Reliability in Interrupted Steel Roughing
Product Overview
The ZCC.CT RCKT1606MO-DR in YBC401 grade is the industrial benchmark for heavy-duty roughing. While the "DM" geometry is for medium work, this DR (Duty Roughing) version is built with a reinforced edge land to withstand massive impact loads. The YBC401 grade is ZCC.CT's toughest CVD-coated carbide, specifically optimized for the ISO P30-P50 range. It excels where other inserts fail: namely, machining through rough scales, welded joints, and severe interrupted surfaces on large-scale steel components.
Key Performance Features
- [!] Ultra-Tough Substrate: The YBC401 grade features a specialized fine-grain substrate that absorbs mechanical shock better than any other P-series grade.
- [!] Reinforced DR Geometry: The "DR" chipbreaker is specifically designed for roughing, featuring a wider land for maximum edge security under heavy feed.
- [!] CVD Al2O3 Coating: Provides superior heat resistance, essential for dry machining and handling the high temperatures generated during heavy metal removal.

Global Machinist Feedback
"The YBC401 is bulletproof. We used it for roughing large forged plates and it didn't chip once."
— Robert S., USA 🇺🇸"DR-Geometrie ist perfekt für schwere Zerspanung. Sehr zuverlässig bei Schnittunterbrechung."
— Hans K., Germany 🇩🇪"Massima resistenza agli urti. Ideale per sgrossatura di fusioni d'acciaio."
— Fabio G., Italy 🇮🇹"Unbeatable cost-per-edge for this size. Very happy with the performance in tough steels."
— Kenji M., Japan 🇯🇵FAQ
Q: What is the difference between DM and DR chipbreakers?
A: DM is for general medium-to-roughing applications. DR is for Heavy Roughing, featuring a reinforced land and stronger cutting edge designed to take more abuse.
Q: Can I use YBC401 for finishing?
A: While you can, it is not optimized for it. Finishing requires sharper edges and higher speeds found in YBC302 or YBC152. YBC401 is built for durability in roughing.
Q: Why choose RCKT1606 over smaller sizes?
A: The larger 16mm diameter and 6.35mm thickness allow for much larger depths of cut and provide more mass to dissipate heat during heavy 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.
