BEYOND WC40-3D-SD39-WC06
Precision 3D Indexable U-Drill | 39mm Industrial CNC Tooling
Efficient 39mm Indexable Holemaking
The BEYOND WC40-3D-SD39-WC06 is a professional-grade high-efficiency indexable insert drill designed for rapid metal removal. As a specialized fast hole U-drill, it features a 39mm cutting diameter with a 3D depth ratio. This tool is engineered for internal cooling drilling, ensuring superior chip evacuation in carbon steel, alloy steel, and heavy-duty industrial applications.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 39.0 mm | 1.535" |
| Shank Diameter | 40.0 mm | 1.575" |
| Effective Drilling Depth | 117.0 mm | 4.606" |
Recommended Cutting Parameters
For optimal performance in metal boring, follow these standard guidelines:
- Cutting Speed (Vc): 100 - 150 m/min (Subject to material hardness).
- Feed Rate (f): 0.06 - 0.15 mm/rev.
- Spindle Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 39}$$
- Coolant: High-pressure internal cooling is mandatory to ensure chip flushing.
Material & Flute Geometry Breakdown
Our indexable tool holder is manufactured from premium alloy steel (20CrMnTi) with specialized quenching to ensure a hardness of 45-50 HRC. The oversized spiral flute geometry is designed for high-volume chip evacuation, preventing chip welding in 39mm drilling. The nickel-plated surface provides excellent corrosion resistance and smooth chip flow during continuous operation.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Excellent economy).
- Stable drilling entry on rough or curved surfaces.
- Lower cutting resistance compared to square insert U-drills.
- Requires stable spindle power for 39mm diameters.
- Standard tolerance is roughly +0.1/+0.2mm (suitable for roughing).
Verified Customer Feedback
"Solid Build" - M. Schmid (Germany)
Handles 39mm holes in structural steel with no issues. Very rigid body.
"Efficient Chips" - Robert L. (USA)
The internal coolant and flute design clear chips out of the 3D depth perfectly.
"Best ROI" - Kenji Y. (Japan)
The 3-edge WC inserts make our drilling costs much lower than before.
"Great Quality" - Liam G. (Australia)
BEYOND brand tools never disappoint. The nickel plating is high-end.
"Precision Fit" - D. Rossi (Italy)
The WC06 inserts fit perfectly. Highly accurate for this price range.
Frequently Asked Questions
Q: Does this include the carbide inserts?
A: No, this is the 39mm U-drill body only. WCMX06 inserts are sold separately.
Q: Can I use this for blind holes?
A: Yes, it is ideal for blind holes and produces a relatively flat bottom compared to twist drills.
Q: What is the benefit of the WC series?
A: WC Trigon inserts offer 3 usable cutting edges, significantly reducing your cost-per-hole compared to SP inserts.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for CNC holemaking success:
- 2D/3D (This Model): Maximum rigidity; best for standard diameter roughing and stable machining.
- 4D: The universal standard; balanced for most general production needs.
- 5D: Specialized long reach drilling; requires high-pressure coolant and reduced feed rates.

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.
