BEYOND WC32-2D-SD35.5-WC06
Industrial 35.5mm 2D Indexable U-Drill | High-Torque CNC Metal Boring
Efficient 35.5mm Indexable Fast Hole Drilling
The BEYOND WC32-2D-SD35.5-WC06 is a professional-grade indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 35.5mm 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.

Advanced Material Integrity & Flute Geometry
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 35.5mm U-drill body offers extreme surface hardness and vibration resistance. This prevents tool deformation during high-torque metal boring. The nickel-plated coating provides industrial-grade rust resistance.
Optimized Spiral Flute: 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 and flushed out through high-pressure internal cooling, preventing chip packing during CNC drilling operations.
Recommended Cutting Parameters
Maximize tool life for your 35.5mm U-drill with these recommended settings:
- Cutting Speed (Vc): 120 - 220 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 35.5}$$
- Coolant Strategy: Internal cooling is mandatory to clear chips effectively.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Excellent stability when entering uneven or curved surfaces.
- Balanced cutting forces reduce spindle vibration.
- Requires high spindle torque for 35.5mm diameter holes.
- Hole tolerance is typical for indexable drills (+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 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: What is the benefit of the 2D depth ratio?
A: 2D drills offer maximum rigidity and stability, allowing for higher feed rates and better accuracy on shorter hole depths.
Quick Tip: 2D-5D CNC Drill Comparison
Choosing the right depth is crucial. 2D drills (like this SD35.5 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.
