BEYOND WC40-3D-SD59-WC08
Heavy-Duty 3D Indexable U-Drill | 59mm Industrial CNC Tooling
Large Diameter 59mm Indexable Holemaking
The BEYOND WC40-3D-SD59-WC08 is a high-torque indexable insert drill engineered for massive material removal in heavy-duty CNC machining. As a specialized large diameter fast hole drill, it utilizes a 59mm cutting diameter with a 3D depth ratio. This tool is the premier choice for high-speed internal cooling drilling, ensuring superior stability and efficiency in carbon steel, alloy steel, and cast iron.
Model Code Specification
Technical Data & Units Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 59.0 mm | 2.322" |
| Shank Diameter | 40.0 mm | 1.574" |
| Effective Depth (3D) | 177.0 mm | 6.968" |
Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 59mm WC drills:
- Cutting Speed (Vc): 100 - 150 m/min (Material dependent).
- Feed Rate (f): 0.10 - 0.22 mm/rev.
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from a 177mm depth.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 59}$$
Material Integrity & Large-Capacity Spiral Flutes
Crafted from high-performance 20CrMnTi alloy steel with specialized vacuum quenching, this WC08 insert holder is built to withstand extreme torque. The oversized spiral flute geometry is designed for "forced" chip removal, significantly reducing the risk of chip-packing in 59mm deep-hole drilling. The nickel-plated surface minimizes friction and prevents chip welding during intensive CNC lathe operations.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Highly cost-efficient).
- Stable entry on rough or curved workpieces.
- Higher feed rates than traditional spade drills.
- Requires high spindle power (kW) for 59mm diameter.
- Tolerance is roughly +0.2mm; usually requires a finishing pass.
Verified Customer Feedback
"Massive Performance" - Klaus M. (Germany)
Handles 59mm bores in forged steel blocks effortlessly. Body rigidity is impressive.
"Best Value U-Drill" - Mark S. (USA)
Switched from expensive brands to BEYOND. No loss in hole quality or tool life.
"Highly Recommend" - Sato T. (Japan)
Excellent internal cooling design. The chips break perfectly in cast iron.
"Fast Shipping" - Liam O. (Australia)
Arrived quickly. The nickel coating is top quality. Very professional tool.
"Industrial Toughness" - Luca R. (Italy)
Using this on a large CNC lathe. The 40mm shank is robust and vibration-free.
Frequently Asked Questions
Q: Does this include the WCMX08 inserts?
A: No, this is the 59mm U-drill body only. It includes the insert screws and the Torx wrench.
Q: Can I use this for through-holes?
A: Yes, it is ideal for both through-holes and blind holes in heavy CNC machining.
Q: What is the benefit of the WC trigon insert?
A: It provides 3 usable cutting edges per insert, reducing your cost-per-hole compared to square inserts.
Pro-Tip: Choosing the Right Depth (2D to 5D)
The L/D ratio is critical for CNC holemaking success:
- 2D/3D (This Model): Maximum rigidity; best for large diameters and machines with high torque but lower RPM.
- 4D: The universal standard for general purpose drilling.
- 5D: Specialized long reach drilling. Requires extreme coolant pressure to maintain 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.
