BEYOND WC32-2D-SD28.5-WC05
Industrial 28.5mm 2D Indexable U-Drill | High-Performance CNC Boring Body
High-Speed 28.5mm Indexable Fast Hole Drilling
The BEYOND WC32-2D-SD28.5-WC05 is a premium indexable insert drill designed for high-efficiency material removal in CNC machining centers. As a specialized fast hole U-drill, it offers a 28.5mm cutting diameter with a 2D depth ratio and a 32mm shank. This tool is engineered for internal cooling drilling across carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for large diameter metal boring projects.
Model Code Specification Breakdown

| Max Drilling Depth (2D) | 57.0 mm | 2.244" |
| Product Model | WC32-2D-SD28.5 | WC1.26-2D-SD1.12 |
Material Excellence & Advanced Flute Design
Durable Tool Body: Built from premium 20CrMnTi alloy steel, the body undergoes a vacuum quenching process to achieve high surface hardness and excellent core toughness. This prevents deformation during high-torque metal boring and ensures stability in high-speed drilling environments.
Optimized Spiral Flute: This indexable drill body features an enlarged spiral flute (U-slot) designed for rapid chip evacuation. The precision U-groove geometry facilitates smooth chip discharge via high-pressure internal cooling, which is critical for maintaining hole accuracy and surface finish.
Recommended Cutting Parameters
Baseline recommendations for the 28.5mm U-drill (Adjust based on material):
- Cutting Speed (Vc): 120 - 200 m/min (Steel); 100 - 160 m/min (Alloy Steel).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 28.5}$$
- Coolant: Internal coolant is mandatory for chip flushing and heat control.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts (3 usable cutting edges for low cost-per-hole).
- Superior stability when entering uneven or inclined surfaces.
- Balanced cutting forces reduce spindle wear on CNC lathes.
- Requires high-pressure coolant for optimal performance.
- Roughing tolerance typically falls within (+0.1/-0.2mm).

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary insert screws and the correct wrench.
Q: Can I use this for through-holes?
A: Yes, it is ideal for both through-holes and flat-bottom blind holes.
Q: What is the benefit of a 32mm shank on a 28.5mm drill?
A: It provides superior clamping stability and vibration reduction compared to smaller shanks.
Quick Tip: 2D-5D CNC Drill Comparison
Choosing the right depth-to-diameter ratio is critical for tool life. 2D drills (like this SD28.5) offer the highest rigidity for high-feed roughing. 3D to 5D drills are for deeper holes but require significantly higher coolant pressure and reduced feed rates to prevent deflection and breakage.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
