BEYOND WC32-3D-SD33-WC06
Precision 3D Indexable U-Drill | 33mm Industrial CNC Tooling
High-Efficiency 33mm Indexable Holemaking
The BEYOND WC32-3D-SD33-WC06 is a professional-grade indexable insert drill engineered for rapid material removal in heavy-duty CNC machining. As a specialized fast hole U-drill, it features a 33mm cutting diameter with a 3D depth ratio. Optimized for high-speed internal cooling drilling, it provides exceptional stability and efficient chip evacuation in carbon steel, alloy steel, and stainless steel.
Model Code Specification
Technical Data & Units Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 33.0 mm | 1.299" |

| Max Drilling Depth (3D) | 99.0 mm | 3.897" |
Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 33mm WC drills:
- Cutting Speed (Vc): 100 - 160 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): $N = \frac{Vc \times 1000}{\pi \times 33}$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from depth.
Material Integrity & Optimized Spiral Flutes
Crafted from high-performance quenched alloy steel (20CrMnTi), this WC06 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 33mm 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 (Economic choice).
- Stable entry on rough or curved workpieces.
- Lower cutting resistance compared to square insert designs.
- Requires high spindle power (kW) for 33mm diameter.
- Tolerance is roughly +0.15mm; best for roughing before finishing.
Verified Customer Feedback
"Highly Robust" - M. Berger (Germany)
Handles 33mm bores in alloy steel blocks effortlessly. Body rigidity is impressive.
"Best Value U-Drill" - James S. (USA)
Switched from expensive brands to BEYOND. No loss in quality or tool life.
"Highly Recommend" - Hiroshi 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 32mm shank is robust and vibration-free.
Frequently Asked Questions
Q: Does this include the WCMX06 inserts?
A: No, this is the 33mm U-drill body only. It includes the insert screws and the Torx wrench.
Q: Can I use this for blind holes?
A: Yes, it is ideal for both through-holes and blind holes in heavy industrial 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 significantly.
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 standard 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.
