BEYOND WC40-5D-SD47-WC08
Professional 5D Indexable U-Drill | Precision Engineering from China
Note: Inserts are not included (Holder Only)
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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
