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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
