BEYOND WC40-3D-SD44-WC08
Industrial 3D Indexable U-Drill | 44mm High-Speed CNC Tooling
High-Precision 44mm Indexable Holemaking
The BEYOND WC40-3D-SD44-WC08 is a heavy-duty indexable insert drill engineered for rapid material removal in high-efficiency CNC machining. As a specialized large diameter fast hole drill, it utilizes a 44mm 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 & Unit Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 44.0 mm | 1.732" |
| Shank Diameter | 40.0 mm | 1.575" |
| Effective Depth (3D) | 132.0 mm | 5.197" |
Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 44mm WC drills:
- Cutting Speed (Vc): 100 - 150 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 44}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from 132mm depth.
Material Integrity & Advanced Flute Design
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 44mm 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 cost-efficiency).
- Balanced cutting forces reduce spindle vibration.
- Faster processing compared to traditional twist drills.
- Requires high spindle power (kW) for 44mm diameters.
- Final hole size may be +0.1mm to +0.2mm over nominal.

Frequently Asked Questions
Q: Does this package include the carbide inserts?
A: No, this is for the 44mm U-drill body only. Inserts are sold separately.
Q: Can I use this for blind holes?
A: Yes, it is ideal for both blind holes and through-holes in high-torque CNC machining.
Q: What material is the drill body made of?
A: It is made from high-strength 20CrMnTi alloy steel with a hardened nickel coating.
Pro-Tip: Choosing the Right Depth (2D to 5D)
The L/D ratio determines your CNC holemaking strategy:
- 2D/3D (This Model): Best for stability and high feed rates. Ideal for standard bores.
- 4D: Balanced for deeper holes where stability is still manageable.
- 5D: Requires reduced feed rates and maximum 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.
