BEYOND WC40-2D-SD49-WC08
Industrial 49mm 2D Indexable U-Drill | High-Torque CNC Performance
High-Efficiency 49mm Indexable Metal Boring
The BEYOND WC40-2D-SD49-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 49mm 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.

Advanced Material Integrity & Flute Geometry
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 49mm U-drill body offers superior surface hardness and vibration resistance. This prevents deformation under high-torque metal boring. The nickel-plated coating provides excellent anti-rust and anti-friction properties.
Optimized Spiral Flutes: This indexable drill body features a 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, maintaining tool stability in CNC drilling operations.
Recommended Cutting Parameters
Maximize your CNC lathe tool efficiency with these baseline settings for the 49mm U-drill:
- Cutting Speed (Vc): 110 - 190 m/min (Depending on material).
- Feed Rate (f): 0.07 - 0.16 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 49}$$
- Coolant: High-pressure internal cooling is mandatory to clear chips effectively.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Exceptional stability on uneven entry surfaces.
- Lower cutting resistance than square insert designs.
- Requires high spindle power (kW) for 49mm bores.
- Typical 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 come with the required insert screws and the matching Torx wrench.
Q: Can I use this for blind holes?
A: Absolutely. The WC U-drill provides a relatively flat bottom, making it perfect for blind hole boring.
Q: Is internal cooling necessary?
A: For a 49mm diameter, internal cooling is highly recommended to flush out chips and protect the carbide edges from overheating.
Quick Tip: 2D vs. 5D Depth Comparison
Choosing the right depth is crucial. 2D drills (like this SD49 model) provide the highest rigidity and are best for roughing. 3D to 5D drills allow for deeper hole reach but require much higher coolant pressure and reduced feed rates to avoid tool deflection 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.
