BEYOND WC40-5D-SD46-WC08
High-Performance 5D Indexable U-Drill | Made in China
Deep Hole CNC Drilling Specialist
The BEYOND WC40-5D-SD46-WC08 is a professional-grade indexable insert drill engineered for heavy-duty metal removal. With a 46mm cutting diameter and a 5D length ratio, this tool is the ultimate choice for high-speed CNC drilling. Designed for stability, it features advanced internal cooling channels to optimize chip evacuation and prevent heat buildup in deep holes.
Technical Code Breakdown
Metric & Imperial Specifications
| Parameter | Metric Unit | Imperial Equivalent |
|---|---|---|
| Cutting Diameter (SD) | 46.0 mm | 1.811" |
| Shank Diameter | 40.0 mm | 1.574" |
| Effective Depth | 230.0 mm | 9.055" |
Recommended Cutting Parameters
To maximize tool life and chip control, please use these reference values:
- Cutting Speed (Vc): 110 - 160 m/min (Adjust based on material)
- Feed Rate (f): 0.07 - 0.14 mm/rev
- Internal Cooling: Mandatory (High-pressure coolant recommended for 5D depth)
Premium Material & Flute Geometry
Constructed from high-strength alloy steel with an advanced nickel-plating process, the drill body provides excellent corrosion and wear resistance. The wide-flute design and spiral geometry facilitate "forced" chip evacuation, preventing chip-packing—a common issue in deep hole drilling. The WC08 insert pocket is precision-machined to ensure rigid clamping, reducing vibration and enhancing the CNC indexable drilling accuracy.

2D-5D U-Drill Selection Guide
Selecting the right depth is crucial for stability:
- 2D/3D Drills: High rigidity, suitable for high-speed shallow holes. Maximum stability.
- 4D Drills: The versatile standard for most manufacturing tasks.
- 5D Drills (This Model): Optimized for deep-hole applications. Requires high-pressure internal coolant. Ensure the CNC spindle is perfectly aligned to avoid deflection.
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.
