Professional 5D Indexable U-Drill | Deep Hole CNC Machining Specialist
High-Efficiency 23.5mm CNC Drilling Solution
The BEYOND WC25-5D-SD23.5-WC04 is an industrial-grade indexable insert drill designed for high-efficiency metal removal. With its 23.5mm cutting diameter and 5D depth-to-diameter ratio, this tool is the ultimate choice for high-speed internal cooling drilling. It provides exceptional stability and superior chip evacuation when processing carbon steel, alloy steel, and stainless steel in deep-hole CNC drilling applications.
Model Code Explained
Technical Data & Metric/Imperial Comparison
| Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 23.5 mm | 0.925" |
| Shank Diameter | 25.0 mm | 0.984" |
| Drilling Depth (5D) | 117.5 mm | 4.626" |
Recommended Cutting Parameters
Optimize your CNC machine tool settings for peak performance:
- Cutting Speed (Vc): 110 - 180 m/min (Adjust based on material hardness).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 5D depth to clear chips effectively.
Material Excellence & Slot Geometry
Constructed from premium alloy steel with specialized anti-vibration heat treatment, the BEYOND U-drill offers extreme durability. The spiral flute geometry is wide-designed for "forced" chip evacuation, which prevents chip-packing—the primary cause of tool failure in 23.5mm deep hole drilling. This WC04 insert holder is nickel-plated for superior corrosion resistance and enhanced tool life.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Better stability on uneven or curved surfaces.
- Superior chip breaking on low-carbon and alloy steels.
- Higher torque requirements than SP series drills.
- Requires precise spindle alignment for deep 5D holes.
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.
