Superior 20CrMnTi Alloy & Spiral Flute Geometry
Durable Tool Material: This 16mm U-drill is crafted from premium 20CrMnTi alloy steel, subjected to vacuum quenching for superior surface hardness and anti-vibration performance. This ensures the indexable drill body remains stable under the high temperatures of high-speed drilling.
Optimized Spiral Flute (U-Groove): Features a precision-engineered spiral flute designed for rapid chip evacuation. The U-groove flute geometry prevents chip packing and heat buildup by utilizing dual internal cooling holes, which flush out metal chips instantly during shallow hole drilling.
Recommended Cutting Parameters
Baseline settings for the 16mm U-drill (Vary by material hardness):
- Cutting Speed (Vc): 120 - 200 m/min.
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 16}$$
- Coolant Strategy: Internal cooling is mandatory for proper chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 cutting edges (Excellent economy).
- Exceptional stability on uneven or curved entry surfaces.
- Low cutting resistance; ideal for lower-power machine spindles.
- Hole tolerance is typical for indexable drills (+0.1/-0.2mm).
- Requires high-pressure coolant pump for deep holes.

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary high-strength screws and the correct Torx wrench.
Q: Can I use this for blind holes?
A: Yes. The WC U-drill provides a relatively flat bottom, perfect for blind hole boring in CNC operations.
Q: Is internal cooling mandatory?
A: Yes. To ensure the 16mm diameter clears chips effectively, internal coolant is essential.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD16 model) offer maximum rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and reduced feed rates to avoid tool deflection.
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.
