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.

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.

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). |
