BEYOND WC40-2D-SD45-WC08
Industrial 45mm 2D Indexable U-Drill | Precision CNC Metal Boring
Efficient 45mm Indexable Fast Hole Drilling
The BEYOND WC40-2D-SD45-WC08 is a professional-grade indexable insert drill engineered for heavy material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 45mm cutting diameter with a 2D depth ratio. This tool is optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for large diameter metal boring projects. Manufactured in China to rigorous industrial standards.

Advanced Material Integrity & Flute Geometry
Body Material: Forged from high-performance quenched alloy steel (20CrMnTi), the 45mm U-drill body offers extreme surface hardness and core toughness. This prevents deformation under high-torque metal boring. The nickel-plated coating provides excellent rust resistance.
Optimized Spiral Flute: This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The chip-breaker slot geometry ensures that chips are broken and flushed out through high-pressure internal cooling, preventing chip packing during CNC drilling operations.
Recommended Cutting Parameters
To maximize the tool life of your 45mm drill, follow these baseline parameters:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 45}$$
- Coolant Strategy: Internal cooling is mandatory. Higher pressure is better for clearing chips.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Stable entry on rough or curved surfaces.
- Lower cutting resistance compared to square insert designs.
- Requires high spindle power (kW) for 45mm diameter.
- Hole tolerance is typical for indexable drills (+0.1/-0.2mm).

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 provides a relatively flat bottom, making it perfect for blind hole boring.
Q: What is the benefit of the 2D depth ratio?
A: The 2D length (90mm for this model) provides the highest rigidity, allowing for faster feeds and better accuracy compared to longer drills.
Quick Tip: 2D-5D CNC Drill Comparison
Choosing the right depth is crucial. 2D drills (like this SD45 model) offer maximum rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and more conservative feed rates to avoid vibration and chip clogging.

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.
