BEYOND WC40-5D-SD39-WC06
Professional 5D Indexable U-Drill | Precision Deep Hole Tooling
High-Efficiency CNC Drilling Solution
The BEYOND WC40-5D-SD39-WC06 is a high-rigidity indexable insert drill engineered for large-scale metal removal. Featuring a 39mm cutting diameter and a 5D depth ratio, this tool is the professional choice for high-speed CNC drilling. Designed for maximum chip evacuation, it excels in processing steel, alloys, and stainless steel with superior stability.
Model Code Explained
Technical Data & Conversion
| Technical Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 39.0 mm | 1.535" |
| Shank Diameter | 40.0 mm | 1.574" |
| Max Drilling Depth | 195.0 mm | 7.677" |
Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Adjust based on material).
- Feed Rate (f): 0.06 - 0.12 mm/rev.
- Coolant Requirement: Internal High-Pressure Coolant is mandatory for 5D depth to clear chips effectively.
WC Type U-Drill: Pros & Cons
- 4 cutting edges per insert (Cost-effective).
- Better stability on uneven entry surfaces.
- Uses widely available WCMX / WCMT inserts.
- Slightly lower feed rates compared to SP series.
- Requires higher torque for deep hole operations.
Material & Flute Geometry
Constructed from high-strength alloy steel with specialized anti-vibration heat treatment. The spiral flute geometry is wide-designed for "forced" chip evacuation, preventing chip-packing—the primary cause of tool breakage in deep hole drilling. This WC06 insert holder is nickel-plated for superior corrosion resistance and prolonged tool body life.
Pro-Tip: Choosing Drill Depth (2D to 5D)
Selecting the correct L/D ratio is critical for CNC tooling performance:
- 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. It requires high-pressure internal coolant and precise spindle alignment to ensure straightness and tool longevity.

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.
