Recommended Cutting Parameters
Achieve optimal metal boring results with these feed and speed recommendations:
- Cutting Speed (Vc): 100 - 160 m/min (Subject to material hardness).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Spindle Speed: $N = \frac{Vc \times 1000}{\pi \times D}$
- Coolant: High-pressure central internal cooling is required for efficient chip flushing.
Premium 20CrMnTi Alloy & Optimized Flute
Constructed from high-performance quenched alloy steel (20CrMnTi), this WC08 insert holder provides maximum toughness and vibration damping. The optimized spiral flute design with a large chip pocket is engineered for rapid chip breaking and evacuation, preventing clogging during deep hole drilling. The nickel-plated surface treatment prevents corrosion and ensures smooth chip flow in high-heat environments.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Excellent economy).
- Stable drilling on uneven surfaces due to balanced cutting forces.
- Higher feed rates than traditional twist drills.
- Requires high spindle power (kW) for 47mm diameter.
- Tolerance is roughly +0.1/+0.2mm (suitable for roughing).

Frequently Asked Questions
Q: Does this include the WCMX08 inserts?
A: No, this is the 47mm drill body only. Inserts must be ordered separately.
Q: Can I use this on a CNC Lathe?
A: Yes, it is suitable for both CNC Machining Centers and CNC Lathes with the correct 40mm holder.
Q: What coolant pressure is recommended?
A: For a 47mm U-drill, we recommend a minimum of 20 bar for optimal chip evacuation.
Pro-Tip: Choosing the Right Depth (2D vs 5D)
- 2D/3D (This Model): Maximum rigidity. Best for high-efficiency boring and stable machining.
- 4D: Balanced choice for general-purpose industrial drilling.
- 5D: Specialized for long reach drilling. Requires reduced feed rates and high-pressure coolant to prevent 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.
