BEYOND WC32-5D-SD37.5-WC06
Precision 5D Indexable U-Drill | High-Speed CNC Tooling
Industrial Grade Deep-Hole Drilling
The BEYOND WC32-5D-SD37.5-WC06 is a heavy-duty indexable insert drill specifically designed for high-speed internal cooling drilling. With a 37.5mm cutting diameter and a 5D depth-to-diameter ratio, this tool body provides the rigidity needed for deep hole CNC drilling in carbon steel, alloy steel, and stainless steel workpieces.
Model Nomenclature Explained
Metric vs. Imperial Specifications
| Technical Feature | Metric (mm) | Imperial (Inch Equivalent) |
|---|---|---|
| Cutting Diameter (SD) | 37.5 mm | 1.476" |
| Shank Diameter | 32.0 mm | 1.259" |
| Max Drilling Depth | 187.5 mm | 7.381" |
Recommended Cutting Parameters
Achieve peak performance for your WC06 U-drill bit with these settings:
- Cutting Speed (Vc): 100 - 160 m/min (Material dependent).
- 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 & Flute Design
This U-drill is manufactured from premium high-strength alloy steel with an anti-vibration quenching process to enhance rigidity. The spiral flute geometry is wide-designed for "forced" chip evacuation, preventing the common "chip-packing" failure in 37.5mm deep-hole drilling applications. The nickel-plated surface ensures excellent corrosion resistance.
WC Series: Advantages & Considerations
- Uses WCMX/WCMT inserts with 4 cutting edges (Cost-effective).
- Exceptional stability on uneven entry surfaces.
- Smooth chip breaking on low-carbon steels.
- Higher torque requirements than SP types.
- Strictly requires precise spindle alignment for 5D depths.
Pro-Tip: Depth Selection (2D vs 5D)
Choosing the right L/D ratio is critical for CNC tooling:
- 2D/3D: Maximum stability; best for high-speed shallow holes.
- 4D: The universal standard for general manufacturing.
- 5D (This Model): Specialized deep-hole drill. It allows for deeper penetration but requires higher coolant pressure and careful chip monitoring to avoid tool breakage.
