BEYOND WC40-2D-SD43-WC08
Industrial 43mm 2D Indexable U-Drill | High-Torque CNC Metal Boring
High-Efficiency 43mm Indexable Hole Boring
The BEYOND WC40-2D-SD43-WC08 is a professional-grade indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 43mm 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 boring projects.

High-Grade Material & Optimized Flute Design
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 43mm U-drill body offers superior surface hardness and vibration resistance. This prevents tool deformation during high-torque boring. The nickel-plated coating provides industrial-grade rust resistance and anti-friction properties.
Optimized Spiral Flutes: This indexable drill body features precision-engineered spiral flute geometry for rapid chip evacuation. The wide chip-breaker grooves ensure that metal chips are broken efficiently and flushed out by internal coolant, protecting the WC08 insert holder from premature wear during CNC drilling operations.
Recommended Cutting Parameters
Maximize your CNC lathe tool efficiency with these baseline settings for the 43mm U-drill:
- Cutting Speed (Vc): 120 - 210 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 43}$$
- Coolant Strategy: Internal cooling is mandatory for high-pressure chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 cutting edges (Low cost-per-hole).
- Stable entry on curved or uneven workpiece surfaces.
- Balanced cutting forces reduce spindle vibration.
- Requires high spindle power (kW) for 43mm diameters.
- Standard tolerance (+0.1/-0.2mm); typically used for roughing.

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, all BEYOND drill bodies include the required insert screws and the matching 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 in metalwork.
Q: Is internal cooling necessary?
A: For a 43mm 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 for stability. 2D drills (like this SD43 model) provide the highest rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper hole reach but require much higher coolant pressure and reduced feed rates to avoid vibration.

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.
