Material & Flute Geometry Analysis
Premium Body Material: Constructed from high-performance quenched alloy steel (20CrMnTi), this 60mm indexable drill is built to withstand extreme torque. The surface is nickel-plated to prevent chip welding and enhance tool life.
Optimized Spiral Flute: The large-capacity spiral flute is designed for efficient "forced" chip evacuation. By utilizing a specific chip-breaker flute geometry, it prevents chip packing, which is a common failure point in large-diameter drilling.
Recommended Cutting Parameters
For optimal performance of the 60mm U-drill, please follow these baseline settings:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Spindle Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 60}$$
- Note: High-pressure internal cooling is required for a 60mm cut to ensure chip flushing.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Very economical).
- Stable entry even on rough surfaces or slanted faces.
- Lower cutting resistance compared to square insert drills.
- Requires high spindle horsepower (kW) for 60mm diameters.
- Dimensional tolerance (+0.1/-0.2mm) is for roughing before finishing.

Frequently Asked Questions
Q: Is this drill suitable for blind holes?
A: Yes, it is ideal for both through-holes and blind holes due to its flat-bottom profile and efficient chip evacuation.
Q: What machine power do I need for a 60mm U-drill?
A: A 60mm diameter requires significant torque. We recommend machines with at least 15kW spindle power for stable operation.
Q: Does the package include the screws and wrench?
A: Yes, the body comes with the insert screws and the correct Torx wrench included.
Pro-Tip: 2D vs. 5D Depth Selection
2D Drill (This Model): Offers maximum rigidity and shortest cycle times for shallow holes up to 120mm deep. Best for accuracy.
3D-5D Drills: Designed for deeper holes. They require much higher coolant pressure and slower feed rates to prevent vibration and ensure chip clearance.
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.
