BEYOND WC25-2D-SD24-WC04
Precision 24mm 2D Indexable U-Drill | High-Performance CNC Boring Body
Efficient 24mm Indexable Fast Hole Drilling
The BEYOND WC25-2D-SD24-WC04 is an industrial-grade indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 24mm cutting diameter with a 2D depth ratio and a 25mm 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.

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
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.
