High-Grade Material & Optimized Flute Design
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), this 50mm U-drill body is designed to absorb vibration and withstand massive torque during heavy machining. The surface is nickel-plated for superior corrosion resistance and anti-friction performance.
Spiral Flute Geometry: The optimized spiral flute design is engineered for efficient chip removal. Combined with internal coolant channels, the flute prevents "chip packing," ensuring continuous operation and protecting the WC08 insert holder from premature wear.
Recommended Cutting Parameters
Optimize your CNC lathe tool efficiency with these baseline settings for the 50mm U-drill:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 50}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing heavy chips.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Lowers cost-per-hole).
- Stable entry even on uneven or curved workpiece surfaces.
- Balanced cutting forces reduce machine spindle wear.
- Requires high spindle power (kW) for 50mm diameters.
- Hole tolerance is roughly +0.10mm to +0.20mm (Roughing grade).

Frequently Asked Questions
Q: Does this drill body fit other brands of WC08 inserts?
A: Yes, it is designed to standard ISO specifications and is compatible with any standard WCMX/WCMT 0804 inserts.
Q: Is this drill suitable for through-holes?
A: Yes, it is perfect for both through-holes and blind holes in CNC metal processing.
Q: What is the benefit of the 2D depth ratio?
A: The 2D length provides the highest rigidity, allowing for faster feed rates and better accuracy on shorter holes compared to 3D or 5D drills.
Quick Tip: 2D vs. 5D Depth Selection
Choosing the right depth is crucial for performance. 2D drills (like this SD50 model) offer maximum rigidity and are best for roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and more conservative feed rates to avoid vibration.
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.
