BEYOND WC40-2D-SD47-WC08
Industrial 47mm 2D Indexable U-Drill | High-Torque CNC Metal Boring
Efficient 47mm Indexable Fast Hole Drilling
The BEYOND WC40-2D-SD47-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 47mm 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 industrial large diameter boring projects. Manufactured in China with premium industrial standards.

Material Integrity & Optimized Flute Design
Premium Body Material: Forged from high-performance quenched alloy steel (20CrMnTi), the 47mm U-drill body offers extreme surface hardness and core toughness. This prevents deformation under high-torque boring. The nickel-plated coating ensures rust resistance and smooth chip flow during heavy machining.
Spiral Flute Geometry: This indexable drill body features precision-engineered spiral flute geometry. The wide chip-breaker grooves ensure metal chips are broken efficiently and flushed out by internal coolant, preventing chip packing during high-feed CNC operations.
Recommended Cutting Parameters
Optimize your CNC lathe tool efficiency with these baseline settings for the 47mm U-drill:
- Cutting Speed (Vc): 110 - 190 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.16 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 47}$$
- Coolant Strategy: Internal cooling is mandatory to clear chips and protect carbide edges.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Economic choice).
- Stable entry even on uneven or curved workpiece surfaces.
- Reduced cutting torque compared to square insert drills.
- Requires high spindle horsepower (kW) for 47mm diameters.
- Tolerance is roughly +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 suitable for blind hole boring in CNC metal parts.
Q: Is internal cooling required?
A: For a 47mm diameter, internal cooling is highly recommended to flush heavy chips and prevent overheating carbide edges.
Quick Tip: 2D vs. 5D Depth Comparison
Choosing the right depth is vital for tool life. 2D drills (like this SD47 model) provide the highest stability 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 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.
