Material Excellence & Advanced Flute Design
Durable Tool Body: Built from premium 20CrMnTi alloy steel, the body undergoes a vacuum quenching process to achieve high surface hardness and excellent core toughness. This prevents deformation during high-torque metal boring and ensures stability in high-speed drilling environments.
Optimized Spiral Flute (U-Slot): This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The precision U-groove geometry facilitates smooth chip discharge via high-pressure internal cooling, which is critical for maintaining hole accuracy and surface finish.
Recommended Cutting Parameters
Baseline recommendations for the 23.5mm U-drill (Adjust based on material):
- Cutting Speed (Vc): 100 - 180 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 23.5}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip flushing and heat control.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (High economy).
- Stable entry on curved or uneven surfaces compared to square insert types.
- Lower cutting resistance, protecting your CNC lathe spindle.
- Hole tolerance is typical for roughing (+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 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 23.5mm diameter, internal cooling is required to flush metal chips and maintain tool life.
Quick Tip: 2D-5D CNC Drill Comparison
Choosing the right depth is crucial. 2D drills (like this SD23.5 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.
