BEYOND WC32-2D-SD27.5-WC05
Professional 27.5mm 2D Indexable U-Drill | High-Speed CNC Metal Boring
High-Efficiency 27.5mm Indexable Fast Hole Drilling
The BEYOND WC32-2D-SD27.5-WC05 is a high-performance indexable insert drill engineered for rapid material removal in CNC machining centers. Known as a heavy-duty fast hole U-drill, it features a 27.5mm cutting diameter with a 2D depth ratio and a 32mm straight shank. This tool is optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for CNC lathe metal boring projects.
Model Code Specification Breakdown
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |

| Cutting Diameter (SD) | 27.5 mm | 1.082" |
| Shank Diameter | 32.0 mm | 1.260" |
| Drilling Depth (2D) | 55.0 mm | 2.165" |
| Model Code | WC32-2D-SD27.5 | WC1-1/4"-2D-SD1.08 |
High-Quality 20CrMnTi Alloy Steel Body
Durable Tool Body: Built from premium 20CrMnTi alloy steel, the body undergoes a rigorous vacuum quenching process to ensure high surface hardness and core toughness. This material prevents tool deformation during high-torque metal boring and provides long-term industrial reliability.
Optimized Spiral Flute (U-Groove): This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The precision chip-breaker slot geometry ensures that metal chips are broken efficiently and flushed out via internal cooling holes, preventing chip packing during high-speed drilling.
Recommended Cutting Parameters
Baseline recommendations for the 27.5mm U-drill (Adjust based on material hardness):
- Cutting Speed (Vc): 120 - 200 m/min (Steel/Alloy).
- Feed Rate (f): 0.07 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 27.5}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip removal.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 usable cutting edges (Highly economical).
- Stable entry on curved or uneven surfaces compared to twist drills.
- Lower cutting forces due to optimized insert positioning.
- Requires high spindle torque for the 27.5mm diameter.
- Roughing tolerance typically falls within (+0.1/-0.2mm).

Expert Q&A
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary 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 mandatory?
A: Yes. For a 27.5mm diameter at speed, internal coolant is essential to flush chips and prevent tool failure.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD27.5 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
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.
