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.

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.
