BEYOND WC25-2D-SD19-WC03
Precision 19mm 2D Indexable U-Drill | High-Performance CNC Boring Body
High-Efficiency 19mm Indexable Fast Hole Drilling
The BEYOND WC25-2D-SD19-WC03 is a professional-grade indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 19mm cutting diameter with a 2D depth ratio and a 25mm straight shank. This tool is optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for large diameter metal boring projects.

Advanced 20CrMnTi Alloy & Spiral Flute Geometry
Durable Tool Body: Manufactured from premium 20CrMnTi alloy steel, this indexable drill body undergoes vacuum quenching to ensure high surface hardness and core toughness. This material prevents tool deformation during high-torque metal boring and provides superior vibration resistance.
Optimized Spiral Flute (U-Slot): Features an enlarged spiral flute designed for rapid chip evacuation. The precision U-groove geometry facilitates smooth chip discharge via internal cooling holes, which is critical for preventing heat buildup and tool breakage during high-speed drilling.
Recommended Cutting Parameters
Optimize your 19mm U-drill performance with these baseline settings:
- Cutting Speed (Vc): 120 - 200 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 19}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WC03 inserts (3 usable cutting edges = high economy).
- Stable entry on curved or uneven surfaces.
- Lower cutting resistance compared to square insert drills.
- Roughing tolerance typically falls within (+0.1/-0.2mm).
- Requires stable internal coolant pressure.

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.
Q: Is internal cooling necessary?
A: Absolutely. At 19mm, internal cooling is required to flush chips and protect the insert life.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD19 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.
