BEYOND WC32-4D-SD35.5-WC06
Industrial 4D Indexable U-Drill | 35.5mm Precision CNC Machining
High-Performance 35.5mm Indexable Drilling
The BEYOND WC32-4D-SD35.5-WC06 is a professional indexable insert drill engineered for large-diameter metal removal. Featuring a 35.5mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. It is optimized for processing carbon steel, alloy steel, and stainless steel with maximum stability during heavy-duty CNC machining.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 35.5 mm | 1.397" |
| Shank Diameter | 32.0 mm | 1.260" |
| Max Drilling Depth (4D) | 142.0 mm | 5.590" |
Recommended Cutting Parameters
Optimize your CNC metalworking results by following these guidelines:
- Cutting Speed (Vc): 110 - 180 m/min (Depending on workpiece material).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant: High-pressure internal coolant is mandatory for 35.5mm diameter to flush chips effectively.
Advanced Material & Wide Spiral Flute Geometry
Constructed from high-performance alloy steel with specialized anti-vibration quenching, this WC06 insert holder ensures maximum rigidity. The wide spiral flute geometry is engineered for "forced" chip removal, preventing chip-clogging—the primary cause of failure in 35.5mm deep hole drilling. The nickel-plated body minimizes friction and prevents chip welding during high-speed operations.
WC Series U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Stable entry even on uneven surfaces.
- Ideal for large hole drilling with stable chip breaking.
- Higher torque requirements than SP series.
- Surface finish may require a finishing pass for high-tolerance bores.
Pro-Tip: Choosing Drill Depth (2D to 5D)
Selecting the right L/D ratio is critical for CNC tooling success:
- 2D/3D: Maximum rigidity; best for shallow holes and high-feed roughing.
- 4D (This Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized deep-hole drill bit. Requires extreme coolant pressure 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.
