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
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.
