BEYOND WC40-4D-SD54-WC08
Industrial 4D Indexable U-Drill | 54mm Large Diameter CNC Tooling
High-Performance 54mm Large Hole Drilling
The BEYOND WC40-4D-SD54-WC08 is a heavy-duty indexable insert drill engineered for large-diameter metal removal. With a 54mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the ultimate choice for high-speed internal cooling drilling. It provides exceptional stability and superior chip evacuation in carbon steel, alloy steel, and stainless steel applications.

Technical Data & Metric/Imperial Comparison
| Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 54.0 mm | 2.126" |

Recommended Cutting Parameters
Achieve optimal results for your 54mm indexable drill bit with these settings:
- Cutting Speed (Vc): 100 - 150 m/min (Adjust based on material type).
- Feed Rate (f): 0.08 - 0.15 mm/rev.
- Coolant: High-pressure internal coolant is mandatory for 4D depth to clear chips effectively.
Material Science & Spiral Flute Design
Constructed from high-strength alloy steel with specialized anti-vibration quenching, this WC08 insert holder ensures maximum rigidity under high torque. The wide spiral flute geometry is specifically designed for high-volume chip removal, preventing chip-packing—the primary cause of tool failure in 54mm 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.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements than SP series.
- Requires high-power CNC spindles for 54mm diameters.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC tooling:
- 2D/3D: Maximum rigidity; ideal for shallow holes and high feed rates.
- 4D (This Model): The sweet spot for industrial deep drilling; provides reach without sacrificing stability.
- 5D: Extreme depth; requires very high coolant pressure and precise alignment to prevent deflection.

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.
