BEYOND WC32-4D-SD26-WC05
Precision 4D Indexable U-Drill | 26mm High-Performance CNC Machining
Industrial-Grade 26mm Indexable Drilling
The BEYOND WC32-4D-SD26-WC05 is a high-rigidity indexable insert drill engineered for rapid metal removal in modern CNC machining. Featuring a 26mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. Optimized for stability, it excels in carbon steel, alloy steel, and stainless steel applications.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 26.0 mm | 1.0236" |
| Shank Diameter | 32.0 mm | 1.2598" |
| Max Drilling Depth (4D) | 104.0 mm | 4.0945" |
Recommended Cutting Parameters
Achieve optimal metal drilling results by following these standard guidelines for the WC series rapid drill:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant Strategy: High-pressure internal cooling is mandatory for 26mm diameters to ensure effective chip evacuation and prolong tool life.
Premium Material & Optimized Flute Design
Crafted from high-performance hardened alloy steel with specialized anti-vibration quenching, this WC05 insert holder provides maximum rigidity. The wide spiral flute geometry is specifically engineered for "forced" chip removal, significantly reducing the risk of chip-packing in 26mm deep hole drilling. The nickel-plated body minimizes friction and prevents chip welding during high-speed operations.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3/4 cutting edges (Highly cost-effective).
- Stable performance on uneven or curved entry surfaces.
- Fast chip breaking on low-carbon and alloy steels.
- Requires higher spindle torque and power.
- Surface finish may require secondary finishing for high-precision 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 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.
