BEYOND WC40-5D-SD44-WC08
Professional 5D Indexable U-Drill | High-Stability Deep Hole Drilling
Deep Hole Precision Machining
The BEYOND WC40-5D-SD44-WC08 is a high-rigidity indexable insert drill engineered for demanding industrial environments. With a 44mm cutting diameter and a 5D length ratio, this tool provides the stability required for high-speed CNC drilling. It features integrated internal cooling to ensure excellent chip evacuation and heat management during extended drilling cycles.
Model Specifications Breakdown
Technical Data & Metric/Imperial Conversion
| Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|

| Shank Diameter | 40.0 mm | 1.574" |
| Max Drilling Depth | 220.0 mm | 8.661" |
Recommended Cutting Parameters
To ensure optimal tool life and effective chip control, please follow these guidelines:
- Cutting Speed (Vc): 110 - 170 m/min (depending on material hardness).
- Feed Rate (f): 0.07 - 0.14 mm/rev.
- Coolant Requirement: Internal High-Pressure Coolant is mandatory for 5D depth to clear chips effectively from the deep flute.
Advanced Material & Flute Geometry
The BEYOND U-Drill body is manufactured from premium alloy steel with an anti-vibration design and specialized quenching for enhanced surface hardness. The spiral flute geometry is wide and polished for "forced" chip evacuation, preventing chip-packing which is common in deep 5D holes. Utilizing WC08 carbide inserts, this holder offers four cutting edges, making it a highly cost-effective CNC tool holder for deep hole drilling.

Pro-Tip: Choosing Drill Depth (2D to 5D)
Selecting the correct L/D ratio is critical for performance:
- 2D/3D Drills: Maximum rigidity. Best for high-speed shallow holes and lathes with less stability.
- 4D Drills: The industry standard for versatile, general-purpose machining.
- 5D Drills (This Model): Specialist tool for deep-hole applications. It requires high-pressure internal coolant and precise spindle alignment to prevent deflection and ensure hole straightness.

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.
