Durable Alloy Steel & Efficient Spiral Flutes
Premium Body Material: This 24mm U-drill is crafted from high-strength 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-Slot): Features an enlarged spiral flute designed for rapid chip evacuation. The precision U-groove geometry works in tandem with dual internal cooling holes to flush chips out instantly, preventing heat buildup and tool deflection in shallow hole drilling.
Recommended Cutting Parameters
Baseline recommendations for the 24mm U-drill (Adjust based on material):
- Cutting Speed (Vc): 100 - 200 m/min (Material dependent).
- Feed Rate (f): 0.06 - 0.16 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 24}$$
- Internal Cooling: Mandatory for chip flushing and cooling the insert edges.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 usable cutting edges (Highly economical).
- Stable entry even on uneven or sloped workpiece surfaces.
- Balanced cutting forces reduce spindle wear on CNC lathes.
- Hole tolerance is slightly wider than solid carbide (+0.1/-0.2mm).
- Requires consistent high-pressure internal coolant.

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary high-strength insert screws and the correct Torx wrench.
Q: Can I use this for through-holes?
A: Yes, it is ideal for both through-holes and flat-bottom blind holes in steel and alloys.
Q: Is internal cooling required?
A: Yes, for indexable U-drills, internal coolant is essential for chip evacuation and maintaining hole accuracy.
Quick Tip: 2D-5D CNC Drill Selection Guide
Choosing the right depth-to-diameter ratio is critical for tool life:
- 2D (This Model): Highest rigidity. Best for high-feed roughing and shallow holes.
- 3D: Standard versatility for most general engineering tasks.
- 5D: Deep-hole specialized. Requires reduced feed rates and maximum coolant pressure to prevent 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.
