Superior 20CrMnTi Alloy & Spiral Flute Geometry
Durable Tool Material: This 16mm U-drill is crafted from premium 20CrMnTi alloy steel, subjected to vacuum quenching for superior surface hardness and anti-vibration performance. This ensures the indexable drill body remains stable under the high temperatures of high-speed drilling.
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 shallow hole drilling.
Recommended Cutting Parameters
Baseline settings for the 16mm U-drill (Vary by material hardness):
- Cutting Speed (Vc): 120 - 200 m/min.
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 16}$$
- Coolant Strategy: Internal cooling is mandatory for proper chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 cutting edges (Excellent economy).
- Exceptional stability on uneven or curved entry surfaces.
- Low cutting resistance; ideal for lower-power machine spindles.
- Hole tolerance is typical for indexable drills (+0.1/-0.2mm).
- Requires high-pressure coolant pump for deep holes.
Verified Customer Feedback

Frequently Asked Questions
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 16mm diameter clears chips effectively, internal coolant is essential.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD16 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.
