BEYOND WC32-5D-SD27-WC05
Professional 5D Indexable U-Drill | High-Stability Deep Hole Tooling
Industrial Precision 27mm Deep Hole Drilling
The BEYOND WC32-5D-SD27-WC05 is a high-performance indexable insert drill designed for high-efficiency metal removal. Featuring a 27mm cutting diameter and a 5D depth-to-diameter ratio, this tool is the professional choice for high-speed internal cooling drilling. Engineered for extreme rigidity, it provides efficient chip evacuation in carbon steel, alloy steel, and stainless steel CNC applications.
Model Code Decoded
Metric vs. Imperial Specifications
| Technical Feature | Metric (mm) | Imperial (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 27.0 mm | 1.063" |

Recommended Cutting Parameters
Achieve peak performance for your 27mm indexable drill bit with these settings:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant: High-pressure internal coolant is mandatory for 5D depth to clear chips and protect the WC05 insert holder.
Material Science & Spiral Flute Geometry
Constructed from premium alloy steel with specialized anti-vibration quenching, this tool body ensures maximum rigidity. The wide spiral flute geometry is designed for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in 27mm deep hole drilling. This WC05 insert holder is nickel-plated for superior corrosion resistance and a longer lifespan in harsh CNC tooling environments.
WC Series U-Drill: Pros & Cons
- Uses WCMX/WCMT inserts with 4 cutting edges (Highly cost-effective).
- Exceptional stability on irregular or curved entry surfaces.
- Superior chip breaking on low-carbon and alloy steels.
- Higher torque requirements compared to SP series drills.
- Sensitive to spindle alignment in deep 5D drilling applications.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for successful CNC drilling:
- 2D/3D: Maximum rigidity; ideal for high-speed shallow holes.
- 4D: The universal standard for general manufacturing.
- 5D (This Model): Specialized deep-hole U-drill. Requires high-pressure coolant and precise alignment to maintain hole straightness and 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.
