BEYOND WC40-4D-SD45-WC08
Industrial 4D Indexable U-Drill | 45mm Precision CNC Machining
High-Efficiency 45mm Indexable Drilling
The BEYOND WC40-4D-SD45-WC08 is a professional-grade indexable insert drill designed for high-torque metal removal. Engineered with high-strength alloy steel and treated with an anti-vibration quenching process, this tool body provides maximum rigidity. The spiral flute geometry is specifically optimized for efficient chip evacuation, preventing chip-clogging—the leading cause of tool failure in 45mm large diameter drilling.
What the Model Number Means
Technical Specifications & Comparison
| Parameter | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Drilling Diameter (SD) | 45.0 mm | 1.772" |
| Shank Diameter (D) | 40.0 mm | 1.575" |
| Effective Drilling Depth | 180.0 mm | 7.087" |
Recommended Cutting Parameters
Achieve optimal CNC tooling results with these standard settings for steel and alloy:
- Cutting Speed (Vc): 100 - 160 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Coolant: High-pressure internal cooling is mandatory for effective chip removal at 4D depths.
WC Series U-Drill Performance
- Uses WCMX / WCMT inserts with 4 cutting edges (economical).
- Excellent performance in large hole CNC machining with stable chip breaking.
- Lower cutting resistance compared to twist drills.
- Higher spindle torque requirements for 45mm diameters.
- Surface finish may be slightly rougher than specialized reaming tools.
Pro-Tip: Choosing the Right Depth (L/D Ratio)
The U-Drill 4D ratio is the sweet spot for balance:
- 2D/3D: Maximum rigidity for high-feed rates on shallow holes.
- 4D (This Model): Universal standard for deep hole drilling without sacrificing tool life.
- 5D: Extreme reach; requires superior internal coolant drilling pressure and reduced feed rates 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.
