Technical Data & Metric/Imperial Conversion
| Technical Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 25.5 mm | 1.004" |

| Max Drilling Depth | 127.5 mm | 5.019" |
Recommended Cutting Parameters
Maximize your CNC machine tool productivity with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Adjust based on material type).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Note: High-pressure internal coolant is mandatory for 5D depth to clear chips effectively.
Material Excellence & Spiral Flute Design
Constructed from premium alloy steel with specialized anti-vibration quenching, this tool body ensures maximum rigidity. The spiral flute geometry is wide-designed for "forced" chip evacuation, which prevents chip-packing—the primary cause of tool failure in 25.5mm deep hole drilling. This WC05 insert holder is nickel-plated for superior corrosion resistance and enhanced tool life.
WC Series U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Highly cost-effective).
- Better stability on uneven or curved entry surfaces compared to SP drills.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements than SP series drills.
- Requires precise spindle alignment for deep 5D applications.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC tooling:
- 2D/3D: Maximum rigidity. Best for high-speed shallow holes.
- 4D: The universal standard for general-purpose machining.
- 5D (This Model): Specialized deep-hole drill. It allows for deep penetration but requires high-pressure internal coolant to ensure straightness and tool longevity.
