Recommended Cutting Parameters
Achieve optimal metal boring performance with these baseline settings:
- Cutting Speed (Vc): 100 - 160 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 46}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for effective chip flushing.
Premium 20CrMnTi Steel & Optimized Flute Design
Constructed from high-performance quenched alloy steel, this WC08 insert holder ensures maximum toughness and vibration damping. The optimized spiral flute geometry is designed for efficient long-chip breaking, preventing clogging during 46mm fast drilling. The nickel-plated surface prevents corrosion and ensures smooth chip flow even in demanding metal boring environments.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 cutting edges (Excellent economy).
- Stable drilling on uneven or sloped entry surfaces.
- Lower cutting resistance compared to larger SP series.
- Requires high-pressure coolant for deep 3D depths.
- Tolerance is roughly +0.15/+0.25mm; not for high-precision H7 bores.

Frequently Asked Questions
Q: Does this include the carbide inserts?
A: No, this is the 46mm U-drill body only. WCMX/WCMT 08 inserts are sold separately.
Q: Can I use this on a conventional lathe?
A: Yes, provided you have a steady 40mm holder and high-pressure coolant supply.
Q: What is the benefit of the WC Trigon insert?
A: It provides 3 usable cutting edges, offering better cost-efficiency than 2-edged square inserts.
Pro-Tip: Choosing the Right Depth (2D to 5D)
- 2D/3D (This Model): Best for shallow to medium holes; offers maximum rigidity for very high feed rates.
- 4D: The universal standard for general industrial applications.
- 5D: Specialized long reach drilling. Requires extreme coolant pressure to maintain hole straightness.
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.
