BEYOND WC32-4D-SD27-WC05
High-Rigidity 4D Indexable U-Drill | 27mm Precision CNC Tooling
Precision 27mm Indexable Drilling Solution
The BEYOND WC32-4D-SD27-WC05 is a high-performance indexable insert drill engineered for rapid metal removal. Featuring a 27mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the ultimate 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 (mm) | Imperial (Inch Equivalent) |
|---|---|---|
| Drill Diameter (SD) | 27.0 mm | 1.063" |
| Shank Diameter | 32.0 mm | 1.260" |
| Drilling Depth (4D) | 108.0 mm | 4.252" |
Recommended Cutting Parameters
Maximize your metal holemaking efficiency with these standard guidelines for WC U-drills:
- Cutting Speed (Vc): 120 - 200 m/min (Subject to material hardness).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 27mm diameters to ensure effective chip evacuation and protect the drill body.
Premium Material & Optimized Spiral Flute
Constructed from high-performance alloy steel with specialized anti-vibration quenching, this WC05 insert holder ensures maximum rigidity. The wide spiral flute geometry is specifically engineered for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in 27mm 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 3/4 cutting edges (Cost-effective).
- Exceptional stability on uneven entry surfaces compared to SP series.
- Excellent chip breaking on low-carbon and alloy steels.
- Requires higher spindle power for 27mm bores.
- 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 (Current Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized long reach drill. Requires extreme coolant pressure and precise alignment.

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.
