BEYOND WC32-4D-SD37-WC06
Precision 4D Indexable U-Drill | 37mm High-Speed CNC Tooling
Industrial 37mm Indexable Drilling Solution
The BEYOND WC32-4D-SD37-WC06 is a high-rigidity indexable insert drill engineered for heavy-duty metal removal. Featuring a 37mm cutting diameter and a 4D depth-to-diameter ratio, this tool is optimized for high-speed internal cooling drilling. It provides exceptional stability and superior chip evacuation in carbon steel, alloy steel, and stainless steel applications during large hole CNC machining.
Model Code Decoded
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model | Imperial Equivalent |
|---|---|---|
| Cutting Diameter (SD) | 37.0 mm | 1.457" |
| Shank Diameter | 32.0 mm | 1.260" |
| Drilling Depth (4D) | 148.0 mm | 5.827" |
Recommended Cutting Parameters
Maximize your WC06 insert holder performance with these settings:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.06 - 0.14 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 4D depth to flush chips effectively and protect the drill body.
Material Excellence & Spiral Flute Design
Constructed from high-strength alloy steel with specialized anti-vibration quenching, this 37mm indexable drill bit offers extreme durability. The wide spiral flute geometry is specifically engineered for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in large diameter drilling. The nickel-plated surface provides excellent 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 entry surfaces compared to SP drills.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements than SP series drills.
- Requires high-power CNC spindles for 37mm diameters.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC metalworking:
- 2D/3D: Maximum rigidity; ideal for shallow holes and high feed rates.
- 4D (This Model): The industrial standard for deep-hole drilling; provides reach without sacrificing stability.
- 5D: Extreme depth; requires very high coolant pressure and precise alignment to prevent 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.
