BEYOND WC40-3D-SD58-WC08
Heavy-Duty 3D Indexable U-Drill | 58mm Industrial CNC Tooling
Large Diameter 58mm Indexable Holemaking
The BEYOND WC40-3D-SD58-WC08 is a high-torque indexable insert drill engineered for massive material removal in heavy-duty CNC machining. As a specialized large diameter fast hole drill, it utilizes a 58mm cutting diameter with a 3D depth ratio. This tool is the premier choice for high-speed internal cooling drilling, ensuring superior stability and efficiency in carbon steel, alloy steel, and cast iron.
Model Code Specification
Technical Data & Units Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 58.0 mm | 2.283" |

Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 58mm WC drills:
- Cutting Speed (Vc): 100 - 150 m/min (Material dependent).
- Feed Rate (f): 0.10 - 0.22 mm/rev.
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from 174mm depth.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 58}$$
Material Integrity & Large-Capacity Spiral Flutes
Crafted from high-performance 20CrMnTi alloy steel with specialized vacuum quenching, this WC08 insert holder is built to withstand extreme torque. The oversized spiral flute geometry is designed for "forced" chip removal, significantly reducing the risk of chip-packing in 58mm deep-hole drilling. The nickel-plated surface minimizes friction and prevents chip welding during intensive CNC lathe operations.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Highly cost-efficient).
- Stable entry on rough or curved workpieces.
- Higher feed rates than traditional spade drills.
- Requires high spindle power (kW) for 58mm diameter.
- Tolerance is roughly +0.2mm; usually requires a finishing pass.

Frequently Asked Questions
Q: Does this include the WCMX08 inserts?
A: No, this is the 58mm U-drill body only. It includes the insert screws and the Torx wrench.
Q: Can I use this for through-holes?
A: Yes, it is ideal for both through-holes and blind holes in heavy CNC machining.
Q: What is the benefit of the WC trigon insert?
A: It provides 3 usable cutting edges per insert, reducing your cost-per-hole compared to square inserts.
Pro-Tip: Choosing the Right Depth (2D to 5D)
The L/D ratio is critical for CNC holemaking success:
- 2D/3D (This Model): Maximum rigidity; best for large diameters and machines with high torque but lower RPM.
- 4D: The universal standard for general purpose drilling.
- 5D: Specialized long reach drilling. Requires extreme coolant pressure to maintain hole straightness.
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.
