High-Quality 20CrMnTi Alloy Steel Body
Superior Material: The BEYOND U-drill body is forged from premium quenched alloy steel (20CrMnTi). This material offers exceptional surface hardness ($$HRC 50-55$$) and core toughness, effectively dampening vibrations during heavy-duty metal boring.
Optimized Spiral Flute (U-Groove): This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The precision chip-breaker slot geometry ensures that metal chips are broken efficiently and flushed out via high-pressure internal cooling, preventing chip packing in deep holes.
Recommended Cutting Parameters
Achieve peak efficiency for your 31mm U-drill with these baseline settings:
- Cutting Speed (Vc): 120 - 220 m/min (Depending on workpiece material).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 31}$$
- Coolant Strategy: Internal cooling is mandatory for chip flushing and heat control.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT trigon inserts with 3 usable cutting edges (High economy).
- Stable entry on uneven or curved surfaces.
- Excellent performance in high-speed drilling applications.
- Requires high spindle torque due to the 31mm diameter.
- Hole tolerance is typically roughing grade (+0.1/-0.2mm).

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, all BEYOND drill bodies include the necessary insert 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 necessary?
A: Absolutely. At 31mm diameter, internal cooling is required to flush metal chips and protect the insert edges.
Pro Tip: 2D vs. 5D Depth Ratios
Choosing the right depth is crucial. 2D drills (like this SD31 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 and breakage.
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.
