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
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
