BEYOND WC32-2D-SD28-WC05
Industrial 28mm 2D Indexable U-Drill | High-Speed CNC Boring Body
High-Efficiency 28mm Indexable Fast Hole Drilling
The BEYOND WC32-2D-SD28-WC05 is a professional indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 28mm cutting diameter with a 2D depth ratio and a 32mm 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.

Premium 20CrMnTi Alloy Steel Body
Durable Tool Body: Built from premium 20CrMnTi alloy steel, the body undergoes a vacuum quenching process to ensure high surface hardness and excellent core toughness. This material prevents tool deformation during high-torque metal boring and resists the high temperatures of high-speed drilling.
Optimized Spiral Flute (U-Slot): This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The precision U-groove flute geometry ensures that metal chips are broken efficiently and flushed out via internal cooling, reducing the risk of chip packing and tool breakage.
Recommended Cutting Parameters
Achieve peak efficiency for your 28mm hole making with these settings:
- Cutting Speed (Vc): 120 - 220 m/min (Depending on workpiece material).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 28}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip flushing and tool protection.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT trigon inserts with 3 usable cutting edges (High economy).
- Stable entry on curved or uneven surfaces compared to square insert types.
- Optimized for balanced cutting forces in large diameter metal boring.
- Requires high spindle torque due to the 28mm diameter.
- Hole tolerance is standard for roughing (+0.1/-0.2mm).

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, all BEYOND drill bodies include 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 28mm diameter, internal cooling is required to flush metal chips and maintain tool life.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD28 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.
