BEYOND WC40-2D-SD44-WC08
Professional 44mm 2D Indexable U-Drill | High-Torque CNC Performance
Efficient 44mm Indexable Metal Boring Solution
The BEYOND WC40-2D-SD44-WC08 is an industrial-grade indexable insert drill designed for high-speed material removal. As a specialized fast hole U-drill, it features a 44mm cutting diameter with a 2D depth ratio. This tool is perfectly optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum heat dissipation for large diameter boring projects.
Model Code Specification Breakdown
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 44.0 mm | 1.732" |
| Shank Diameter | 40.0 mm | 1.575" |
| Drilling Depth (2D) | 88.0 mm | 3.464" |
| Model Reference | WC40-2D-SD44 | WC1.57-2D-SD1.73 |
Advanced Material Integrity & Flute Geometry
Hardened Body Material: Forged from high-performance quenched alloy steel (20CrMnTi), the 44mm U-drill body offers superior surface hardness and vibration resistance. This prevents deformation under high-torque boring. The nickel-plated coating provides rust resistance and smooth chip flow.
Optimized Spiral Flutes: This indexable drill body features a precision-engineered spiral flute geometry for rapid chip evacuation. The wide chip-breaker grooves ensure metal chips are broken efficiently and flushed out by internal coolant, protecting the CNC lathe tool during heavy operations.
Recommended Cutting Parameters
Maximize your CNC machining efficiency with these baseline settings for the 44mm drill:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 44}$$
- Coolant Strategy: Internal cooling is mandatory for high-pressure chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Stable entry even on uneven or curved surfaces.
- Balanced cutting forces reduce spindle vibration.
- Requires high spindle horsepower (kW) for 44mm diameters.
- Standard tolerance (+0.1/-0.2mm); best for roughing.

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, all BEYOND drill bodies include the necessary insert screws and the correct Torx wrench.
Q: Can I use this for blind holes?
A: Yes. The WC U-drill creates a relatively flat bottom, making it perfect for blind hole boring in metalwork.
Q: Is internal cooling mandatory?
A: For a 44mm diameter, internal cooling is highly recommended to flush heavy chips and prevent overheating carbide edges.
Quick Tip: 2D vs. 5D Depth Selection
Choosing the right depth is vital. 2D drills (like this SD44 model) provide the highest rigidity and are best for roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and reduced feed rates to avoid tool deflection.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
