BEYOND WC40-3D-SD43-WC08
High-Performance 3D Indexable U-Drill | 43mm Industrial CNC Tooling
Precision 43mm Indexable Holemaking
The BEYOND WC40-3D-SD43-WC08 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 43mm 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 stainless steel workpieces.
Model Code Specification
Technical Data & Units Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 43.0 mm | 1.693" |
| Shank Diameter | 40.0 mm | 1.575" |
| Effective Depth (3D) | 129.0 mm | 5.078" |
Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 43mm WC drills:
- Cutting Speed (Vc): 100 - 160 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 43}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from 129mm depth.
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 43mm 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 (High economy).
- Stable entry on rough or curved surfaces.
- Lower power consumption than SP series for the same diameter.
- Requires high spindle torque for 43mm diameter.
- Tolerance is roughly +0.15mm; usually requires a finishing pass.
Verified Customer Feedback
"Highly Robust" - Hans W. (Germany)
Handles 43mm bores in alloy steel blocks effortlessly. Rigidity is world-class.
"Excellent Chip Flow" - Jason P. (USA)
The spiral flutes clear chips perfectly. No clogging at 3D depth.
"Professional Tooling" - Sato R. (Japan)
Great internal cooling design. The nickel coating is very durable.
"Fast Delivery" - Liam N. (Australia)
Arrived quickly. Excellent packaging. Works great on our large CNC lathe.
"Perfect Fit" - Alessandro T. (Italy)
The 40mm shank is precise. Using it with WCMX08 inserts with zero issues.
Frequently Asked Questions
Q: Does this include the WCMX08 inserts?
A: No, this is the 43mm U-drill body only. WCMX/WCMT08 inserts are sold separately.
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.
Q: Is this drill body through-coolant compatible?
A: Yes, it features dual internal coolant channels for high-pressure cooling.
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 high feed rates.
- 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.
