Deep Hole CNC Drilling Solution
The BEYOND WC40-5D-SD47-WC08 is a high-rigidity indexable insert drill designed for heavy-duty metal removal. With a 47mm cutting diameter and a 5D depth-to-diameter ratio, this tool is the industry standard for deep-hole CNC drilling. It features optimized internal coolant channels to ensure maximum tool life and superior chip evacuation in steel, alloy, and stainless steel applications.
Model Code Explanation
Metric & Imperial Comparison
| Specifications | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 47.0 mm | 1.850" |
| Shank Diameter | 40.0 mm | 1.574" |
| Max Drilling Depth | 235 mm | 9.251" |
Recommended Cutting Parameters
For optimal surface finish and tool longevity during high-speed operation:
- Cutting Speed (Vc): 100 - 170 m/min (depending on material hardness).
- Feed Rate (f): 0.06 - 0.14 mm/rev.
- Coolant Requirement: Internal High-Pressure Coolant is mandatory for 5D depth to clear chips effectively.
Advanced Material & Flute Geometry
Constructed from high-strength alloy steel with an anti-vibration design, the drill body undergoes a specialized quenching process to enhance surface hardness. The spiral flute geometry is wide-designed for "forced" chip evacuation, preventing chip-packing which is common in deep 5D holes. Utilizing WC08 carbide inserts, this holder offers four cutting edges per insert, making it a highly cost-effective CNC tool holder.

U-Drill Depth Comparison (2D to 5D)
Choosing the right length is critical for stability:
- 2D/3D: Best for high-speed, shallow holes. Offers maximum rigidity and higher feed rates.
- 4D: A balance between depth and stability for general purpose machining.
- 5D (This Model): Designed for deep-hole drilling. Requires stable spindle alignment and high-pressure internal coolant to prevent vibration and ensure accuracy.
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.
