Advanced Material Integrity & Flute Geometry
Body Material: Forged from quenched alloy steel (20CrMnTi), the 59mm U-drill body offers superior surface hardness and core toughness. This prevents deformation under high-torque heavy machining. The nickel-plated coating provides excellent corrosion resistance and anti-friction properties.
Optimized Spiral Flute: This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The chip-breaker slot geometry ensures that even long-stringy chips are broken down and flushed out through high-pressure internal cooling channels.
Recommended Cutting Parameters
To maximize the tool life of your 59mm drill, follow these baseline parameters:
- Cutting Speed (Vc): 100 - 180 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 59}$$
- Coolant Strategy: Internal cooling is mandatory. Higher pressure is better for 59mm bores.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Stable entry on rough or curved surfaces.
- Lower cutting resistance compared to square insert designs.
- Requires high spindle power (kW) for 59mm diameter.
- Hole tolerance is typical for indexable drills (+0.1/-0.2mm).

Frequently Asked Questions
Q: Does this include the carbide inserts?
A: No, this is the drill body only. It includes the insert screws and the Torx wrench.
Q: Can I use this for through-holes?
A: Yes, it is ideal for both through-holes and blind holes in heavy industrial CNC machining.
Q: What is the benefit of the 2D depth ratio?
A: A 2D depth (118mm for this model) provides the highest rigidity, allowing for faster feeds and better accuracy compared to longer drills.
Quick Tip: 2D vs. 5D Depth Comparison
2D Drills: Maximum stability, best for shallow boring and high-feed roughing.
3D-5D Drills: Designed for deep hole drilling; requires high-pressure coolant and reduced feed rates to ensure proper chip evacuation and avoid tool 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.
