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
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.
