BEYOND WC32-4D-SD38.5-WC06
Industrial 4D Indexable U-Drill | 38.5mm Precision CNC Machining
High-Efficiency 38.5mm Indexable Drilling
The BEYOND WC32-4D-SD38.5-WC06 is a professional indexable insert drill engineered for high-performance metal removal. Featuring a 38.5mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. Optimized for large hole CNC machining, it provides exceptional stability in carbon steel, alloy steel, and stainless steel applications.
What the Model Number Means
Technical Specifications & Unit Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 38.5 mm | 1.516" |
| Shank Diameter | 32.0 mm | 1.260" |
| Drilling Depth (4D) | 154.0 mm | 6.063" |
Recommended Cutting Parameters
Maximize your WC06 insert holder performance with these settings:
- Cutting Speed (Vc): 110 - 170 m/min (Subject to material hardness).
- Feed Rate (f): 0.06 - 0.12 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 38.5mm diameter to flush chips effectively and ensure tool longevity.
Material Excellence & Spiral Flute Geometry
Constructed from high-performance alloy steel with specialized anti-vibration quenching, this indexable drill bit ensures maximum rigidity. The wide spiral flute geometry is precision-machined for "forced" chip removal, significantly reducing chip-packing in 38.5mm deep hole drilling. The nickel-plated body provides excellent corrosion resistance and reduces friction during high-speed operations.
WC Series U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Highly cost-effective).
- Stable entry even on uneven or curved workpiece surfaces.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements compared to SP series drills.
- Surface finish may require a finishing pass for high-tolerance bores.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for CNC tooling success:
- 2D/3D: Maximum rigidity; best for shallow holes and high-feed rates.
- 4D (This Model): The balanced industrial standard for deep-hole machining.
- 5D: Specialized deep-hole drill bit. Requires extreme coolant pressure and precise feed control to maintain hole straightness.

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.
