BEYOND WC40-5D-SD50-WC08
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) |
| Effective Depth | 250 mm | 9.842" |
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). |
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
