BEYOND WC25-3D-SD18-WC03
Precision 3D Indexable U-Drill | 18mm Industrial CNC Tooling
High-Efficiency 18mm Indexable Holemaking
The BEYOND WC25-3D-SD18-WC03 is a professional-grade indexable insert drill engineered for rapid material removal in heavy-duty CNC machining. As a specialized fast hole U-drill, it features an 18mm cutting diameter with a 3D depth ratio. Optimized for high-speed internal cooling drilling, it provides exceptional stability and efficient chip evacuation in carbon steel, alloy steel, and stainless steel.

Material Integrity & Optimized Spiral Flutes
Body Material: Crafted from high-performance quenched alloy steel (20CrMnTi), this WC03 insert holder is built to withstand extreme torque. The nickel-plated surface minimizes friction and prevents chip welding during intensive CNC lathe operations.
Spiral Flute Design: The oversized spiral flute geometry is designed for "forced" chip removal, significantly reducing the risk of chip-packing in 18mm deep-hole drilling.
Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 18mm WC drills:
- Cutting Speed (Vc): 120 - 220 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.10 mm/rev.
- Rotation Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 18}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from depth.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Economic choice).
- Stable entry on rough or curved workpieces.
- Lower cutting resistance compared to square insert designs.
- Requires high spindle power (kW) for an 18mm diameter.
- Tolerance is roughly +0.15mm; best for roughing before finishing.

Frequently Asked Questions
Q: Does this include the WCMX03 inserts?
A: No, this is the 18mm U-drill body only. It includes the insert screws and the Torx wrench.
Q: Can I use this for blind holes?
A: Yes, it is ideal for both through-holes and blind holes in industrial metal boring.
Q: What is the benefit of the WC trigon insert?
A: It provides 3 usable cutting edges per insert, reducing your cost-per-hole significantly.
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.
