BEYOND WC40-2D-SD48-WC08
Industrial 48mm 2D Indexable U-Drill | Precision CNC Metal Boring
Efficient 48mm Indexable Fast Hole Drilling
The BEYOND WC40-2D-SD48-WC08 is a heavy-duty indexable insert drill designed for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 48mm cutting diameter with a 2D depth ratio. This tool is engineered for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring high stability for large diameter metal boring projects. Manufactured in China with premium industrial standards for longevity and performance.

Material Integrity & Optimized Flute Design
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 48mm U-drill body offers extreme surface hardness and vibration damping. This prevents deformation under high-torque boring. The nickel-plated coating ensures rust resistance and smooth chip flow.
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 heavy CNC operations.
Recommended Cutting Parameters
Optimize your CNC lathe tool efficiency with these baseline settings for the 48mm U-drill:
- Cutting Speed (Vc): 110 - 190 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.16 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 48}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip evacuation.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 cutting edges (Economical).
- Stable entry on uneven or curved workpiece surfaces.
- Lower cutting resistance compared to square insert drills.
- Requires high spindle horsepower (kW) for 48mm diameters.
- Tolerance is roughly +0.1/-0.2mm; best for roughing applications.

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 holes.
Q: Is internal cooling necessary?
A: For a 48mm diameter, internal cooling is highly recommended to flush out heavy chips and prevent overheating.
Quick Tip: 2D vs. 5D Depth Selection
Choosing the right depth is vital. 2D drills (like this SD48 model) offer 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.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
