BEYOND WC25-3D-SD25-WC05
High-Performance 3D Indexable U-Drill | 25mm Precision Tooling
Industrial 25mm Indexable Holemaking Solution
The BEYOND WC25-3D-SD25-WC05 is a premium indexable insert drill engineered for rapid material removal in CNC machining. As a specialized fast hole U-drill, it features a 25mm cutting diameter with a 3D depth ratio. Optimized for high-speed internal cooling drilling, it provides exceptional stability and efficient chip evacuation when working with carbon steel, alloy steel, and stainless steel.
Understanding the Model Code
| WC: | Compatible with WC (Trigon) style indexable inserts. |
| 25: | Shank Diameter (25mm) for standard CNC tool holders. |
| 3D: | Drilling Depth is 3 times the diameter (3 x 25mm = 75mm). |
| SD25: | Cutting Diameter (Size Diameter) is 25mm. |
| WC05: | Specifically designed to fit WC05 series inserts. |
Technical Data & Units Comparison
| Parameter | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter | 25.00 mm | 0.984" |
| Shank Diameter | 25.00 mm | 0.984" |
| Max Drilling Depth | 75.00 mm | 2.953" |
Material & Flute Geometry
Body Material: Crafted from high-strength quenched alloy steel (20CrMnTi), this WC05 insert holder is built to withstand extreme torque and high temperatures. The surface is treated with a specialized coating to prevent corrosion and chip welding.
Spiral Flute Design: The optimized spiral chip flute geometry is designed for "forced" chip removal. By widening the evacuation path, it significantly reduces the risk of chip-packing in 25mm deep-hole drilling, ensuring smoother metal boring and preventing tool breakage.
Recommended Cutting Parameters
Optimize your CNC lathe drilling efficiency with these baseline settings:
- Cutting Speed (Vc): 100 - 180 m/min (Material dependent)
- Feed Rate (f): 0.05 - 0.15 mm/rev
- Rotation Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 25}$$
- Note: Always use high-pressure internal coolant to ensure chip clearance.
Pros & Cons of WC U-Drills
- Trigon WCMX / WCMT inserts provide 3 usable cutting edges, lowering cost-per-hole.
- Excellent stability even when drilling on irregular or curved surfaces.
- Lower cutting resistance compared to square insert drills.
- Requires high spindle power; not suitable for low-torque machines.
- Standard tolerance is approx. +0.1mm to +0.2mm (Roughing tool).

Frequently Asked Questions
Q: Can this 25mm U-drill be used on a manual lathe?
A: It is primarily designed for CNC machines with high-pressure internal cooling. Manual lathes often lack the RPM and coolant pressure required for optimal chip evacuation.
Q: Which inserts should I use for aluminum?
A: We recommend using polished WCMX05 inserts specifically graded for non-ferrous materials for the best surface finish.
Pro-Tip: Choosing the Right Depth Ratio
The L/D ratio (Length to Diameter) is critical for industrial drilling success:
- 2D/3D (This Model): Provides maximum rigidity; best for most general-purpose CNC machining and stable holemaking.
- 4D/5D: Ideal for long reach drilling. Requires specialized deep hole drilling cycles and much higher coolant pressure to prevent chip buildup.
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.
