Material Excellence & Advanced Flute Geometry
Superior Body Material: Forged from high-strength 20CrMnTi alloy steel, the body is vacuum-quenched to achieve a balance of surface hardness and core toughness. This prevents deformation during high-torque metal boring and resists the wear and tear of continuous industrial use.
Precision Spiral Flute: This indexable drill body features an optimized spiral flute designed for rapid chip evacuation. The specific U-groove flute geometry reduces friction and facilitates the smooth discharge of chips through internal coolant channels, crucial for maintaining accuracy in CNC drilling operations.
Recommended Cutting Parameters
Baseline recommendations for the 31.5mm U-drill (Adjust based on machine rigidity):
- Cutting Speed (Vc): 120 - 200 m/min (Mild Steel); 100 - 160 m/min (Alloy Steel).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 31.5}$$
- Coolant: Internal coolant supply is mandatory for heat dissipation and chip flushing.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts (3 cutting edges for high cost-efficiency).
- Exceptional stability when drilling through uneven or curved surfaces.
- Better balanced cutting forces compared to square insert drills.
- Requires higher spindle power for 31.5mm diameters.
- Hole tolerance is generally (+0.1/-0.2mm); not for precision reaming.

Frequently Asked Questions
Q: Is this drill body suitable for 31.5mm through-holes?
A: Yes, it is excellent for both through-holes and blind-holes in all standard CNC metal boring tasks.
Q: Does it include the insert screws?
A: Yes, each BEYOND drill body comes with the necessary Torx screws and wrench.
Q: Can I use this on a manual lathe?
A: It is recommended for CNC machines due to the feed rate and internal cooling requirements needed for 31.5mm diameters.
Selection Guide: 2D-5D CNC Drill Comparison
Rigidity decreases as depth increases. 2D drills (like this SD31.5) offer maximum rigidity, allowing for the highest feed rates. 3D to 5D drills are used for deeper cavities but require higher coolant pressure and reduced feed rates to prevent 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.
