Superior 20CrMnTi Alloy & Spiral Flute Design
Durable Body Material: This indexable drill body is forged from 20CrMnTi alloy steel, treated with vacuum quenching for extreme surface hardness and a shock-absorbing core. This construction effectively dampens vibrations during shallow hole drilling, protecting your spindle and extending insert life.
Optimized Spiral Flute (U-Groove): Features a precision-engineered spiral flute designed for rapid chip evacuation. The U-groove flute geometry prevents chip packing and heat buildup by utilizing dual internal cooling holes, which flush out metal chips instantly during high-speed operations.
Recommended Cutting Parameters
Baseline settings for the 15mm U-drill (Vary by workpiece material):
- Cutting Speed (Vc): 120 - 210 m/min (Standard Steel).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 15}$$
- Note: Internal high-pressure coolant is essential for tool longevity.
WC Type U-Drill: Advantages & Considerations
- Uses WC series inserts (Trigon style) with 3 cutting edges for extreme cost-efficiency.
- Stable entry on curved or angled surfaces.
- Lower spindle load compared to square-insert drills.
- Roughing tool; hole tolerance typically (+0.1 / -0.2mm).
- Coolant pressure determines chip breaking effectiveness.

Expert Q&A
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary high-strength 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. To ensure the 15mm diameter clears chips effectively and doesn't overheat, internal coolant is essential.
Quick Tip: 2D vs. 5D Performance
Choosing the right depth is crucial. 2D drills (like this SD15 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.
