Recommended Cutting Parameters
Optimize your metal boring efficiency with these baseline settings for 38.5mm WC drills:
- Cutting Speed (Vc): 100 - 160 m/min (Material dependent).
- Feed Rate (f): 0.06 - 0.15 mm/rev.
- Rotation Speed: $$N = \frac{Vc \times 1000}{\pi \times 38.5}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing chips from 115.5mm depth.
Material Integrity & Advanced Flute Design
Crafted from high-performance 20CrMnTi alloy steel with specialized vacuum quenching, this WC06 insert holder is built to withstand extreme torque. The oversized spiral flute geometry is designed for "forced" chip removal, significantly reducing the risk of chip-packing in 38.5mm deep-hole drilling. The nickel-plated surface minimizes friction and prevents chip welding during intensive CNC lathe operations.
WC U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (High cost-efficiency).
- Balanced cutting forces reduce spindle vibration.
- Faster processing compared to traditional twist drills.
- Requires high spindle power (kW) for 38.5mm diameters.
- Final hole size may be +0.1mm to +0.2mm over nominal.

Frequently Asked Questions
Q: Does this package include the carbide inserts?
A: No, this is for the 38.5mm U-drill body only. Inserts are sold separately.
Q: Can I use this for blind holes?
A: Yes, it is ideal for both blind holes and through-holes in high-torque CNC machining.
Q: What material is the drill body made of?
A: It is made from high-strength 20CrMnTi alloy steel with a hardened nickel coating.
Pro-Tip: Choosing the Right Depth (2D to 5D)
The L/D ratio determines your CNC holemaking strategy:
- 2D/3D (This Model): Best for stability and high feed rates. Ideal for standard bores.
- 4D: Balanced for deeper holes where stability is still manageable.
- 5D: Requires reduced feed rates and maximum 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.
