BEYOND WC25-2D-SD15-WC03
Precision 15mm 2D Indexable U-Drill | High-Speed CNC Boring Body
Efficient 15mm Indexable Fast Hole Drilling
The BEYOND WC25-2D-SD15-WC03 is a high-performance indexable insert drill engineered for rapid material removal in modern CNC machining. As a specialized fast hole U-drill, it features a 15mm cutting diameter with a 2D depth ratio. This internal cooling drill is optimized for CNC lathe metal boring, ensuring superior chip evacuation and thermal stability in steel, alloy, and stainless steel workpieces.

High-Strength 20CrMnTi Alloy & Spiral Flute Geometry
Durable Body Material: This indexable drill body is forged from 20CrMnTi alloy steel, treated with vacuum quenching for extreme surface hardness and a shock-absorbing core. This construction effectively dampens vibrations during shallow hole drilling, protecting your spindle and extending insert life.
Optimized Spiral Flute (U-Groove): The spiral flute geometry is precision-machined to facilitate rapid chip evacuation. Unlike standard twist drills, the enlarged U-slot combined with dual internal cooling holes flushes chips away from the cutting zone instantly, preventing chip re-cutting and heat buildup.
Recommended Cutting Parameters
Optimize your 15mm U-drill performance with these baseline settings:
- Cutting Speed (Vc): 120 - 200 m/min (Standard Steel).
- Feed Rate (f): 0.05 - 0.10 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 15}$$
- Coolant Strategy: Internal cooling is mandatory to ensure chip flushing at 15mm diameters.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 cutting edges (high cost-efficiency).
- Stable entry on curved or angled surfaces.
- Lower cutting resistance compared to square insert drills.
- Hole tolerance is roughly (+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 boring out existing holes?
A: Yes, U-drills are excellent for both starting from solid and enlarging existing holes.
Q: Is internal cooling necessary?
A: Yes, to prevent heat buildup and ensure chip clearance, internal coolant is highly recommended.
Quick Tip: 2D vs. 5D Comparison
Choosing the right depth is crucial. 2D drills (like this SD15 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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
