Professional 5D Indexable U-Drill | Made in China
High-Performance Indexable Drilling
The BEYOND WC40-5D-SD50-WC08 is a heavy-duty indexable insert drill designed for deep-hole drilling applications. Featuring a 5D depth-to-diameter ratio, this tool excels in creating 50mm holes with precision and speed. Engineered for CNC lathes and machining centers, it utilizes WC08 carbide inserts to ensure maximum productivity in steel, alloy, and stainless steel processing.
Understanding the Model: WC40-5D-SD50-WC08
Metric & Imperial Specifications
| Feature | Metric Unit | Imperial Equivalent |
|---|---|---|
| Cutting Diameter (SD) | 50.0 mm | 1.9685" |
| Shank Diameter | 40.0 mm | 1-1/2" (Approx) |

Recommended Cutting Parameters
To achieve the best surface finish and tool longevity, please follow these guidelines:
- Cutting Speed (Vc): 100 - 180 m/min (Material dependent)
- Feed Rate (f): 0.06 - 0.12 mm/rev
- Coolant: Internal High-Pressure Coolant is highly recommended for 5D depth to ensure chip evacuation.
*Note: Reduce feed by 30% when entering uneven surfaces.
Material & Chipbreaker Geometry
Our U-drill bodies are manufactured from premium alloy steel with high-temperature quenching, providing excellent rigidity and vibration resistance. The WC08 insert pocket is designed for WCMX/WCMT inserts, featuring a specialized chipbreaker groove that breaks long chips into small, manageable curls, preventing "bird-nesting" in deep holes.
Long-tail Keywords: 50mm large diameter U-drill, 5D deep hole indexable drill, WC08 carbide insert holder, CNC internal cooling drill bit.
Grade Comparison Pro-Tips
Choosing the right insert grade for your WC40-5D-SD50 drill:
| General Purpose: | PVD coated grades for P/K/M materials (Steel/Cast Iron/Stainless). |
| Hardened Steel: | Look for Thick CVD coatings for high heat resistance. |
| Aluminum: | Use Polished (Uncoated) inserts to prevent built-up edge (BUE). |

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.
