BEYOND WC25-4D-SD22-WC04
Professional 4D Indexable U-Drill | 22mm Precision CNC Drilling
High-Performance 22mm Indexable Drilling
The BEYOND WC25-4D-SD22-WC04 is a high-rigidity indexable insert drill engineered for rapid metal removal in modern CNC machining. Featuring a 22mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the ultimate choice for high-speed internal cooling drilling. Optimized for stability, it excels in carbon steel, alloy steel, and stainless steel applications.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 22.0 mm | 0.866" |
| Shank Diameter | 25.0 mm | 0.984" |
| Max Drilling Depth (4D) | 88.0 mm | 3.464" |
Cutting Parameters Recommendation
Optimize your metal drilling results with these baseline settings for the WC series rapid drill:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant Strategy: High-pressure internal cooling is mandatory for 22mm diameters to ensure effective chip evacuation and prevent thermal fatigue.
Material Integrity & Advanced Flute Geometry
Crafted from high-performance quenched alloy steel, this WC04 insert holder is built to withstand extreme centrifugal forces. The large-capacity spiral flute is designed for "forced" chip removal, significantly reducing the risk of chip-packing in 22mm deep hole drilling. The tool surface is treated with a specialized coating to minimize friction and prevent chip welding during high-speed feed cycles.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Highly cost-effective).
- Superb performance on uneven entry surfaces.
- Excellent chip breaking on low-carbon and alloy steels.
- Requires higher spindle power compared to standard drills.
- Slightly lower surface finish precision compared to reaming.
Trusted by Global CNC Operators
"The stability of the 4D length on my Haas machine is impressive. Best value 22mm drill I've found."
— Jurgen K., Germany ⭐⭐⭐⭐⭐"Fast shipping to the US. The internal coolant ports are perfectly aligned. Using WC04 inserts."
— Mike R., USA ⭐⭐⭐⭐⭐"Very rigid body. We use this for batch processing 4140 steel. Exceptional tool life."
— Hiroshi S., Japan ⭐⭐⭐⭐⭐Questions & Answers
Q: Does this include the carbide inserts?
A: No, this is the tool holder body only. It includes the insert screws and the Torx wrench.
Q: Can this be used for through-hole drilling?
A: Absolutely. It is designed for both through-hole and blind-hole high-speed CNC machining.
Q: What is the benefit of the 4D ratio?
A: It allows you to drill up to 4 times the diameter (88mm) while maintaining structural integrity.
Pro-Tip: Choosing Drill Depth (2D to 5D)
- 2D/3D: Maximum rigidity; best for shallow holes and high-feed roughing.
- 4D (This Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized deep-hole drill bit. Requires extremely high 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.
