High-Performance 5D Indexable U-Drill | Precision CNC Drilling
Deep Hole CNC Drilling Specialist
The BEYOND WC40-5D-SD42-WC08 is a premium indexable insert drill engineered for heavy-duty metal removal. Featuring a 42mm cutting diameter and a 5D depth-to-diameter ratio, this tool is the ultimate choice for high-speed internal cooling drilling. Designed for maximum rigidity, it excels in processing carbon steel, alloy steel, and stainless steel with superior hole accuracy.
Model Specifications Decoded
Technical Data & Metric/Imperial Conversion
| Technical Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 42.0 mm | 1.653" |
| Shank Diameter | 40.0 mm | 1.574" |

Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.07 - 0.15 mm/rev.
- Coolant Requirement: High-pressure internal cooling is mandatory for 5D depth to ensure effective chip evacuation.
Advanced Material & Flute Geometry
Constructed from high-strength alloy steel with specialized anti-vibration quenching, the BEYOND U-Drill offers exceptional durability. The spiral flute geometry is wide-designed for "forced" chip removal, preventing chip-packing during deep hole drilling. Using WC08 carbide inserts, this holder features four cutting edges per insert, making it a highly cost-effective CNC tooling solution.
WC Type U-Drill: Pros & Cons
- 4 cutting edges per insert (Economic).
- Better stability on uneven entry surfaces.
- Widely available WCMX/WCMT insert compatibility.
- Slightly lower feed rates than SP types.
- Higher thrust requirements for large diameters.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range:
- 2D/3D: Maximum rigidity. Best for high-speed shallow holes.
- 4D: The universal standard for general-purpose machining.
- 5D (This Model): Specialized deep-hole drill. Requires high-pressure internal coolant and precise spindle alignment to ensure 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.
