Advanced Material Integrity & Flute Geometry
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 49mm U-drill body offers superior surface hardness and vibration resistance. This prevents deformation under high-torque metal boring. The nickel-plated coating provides excellent anti-rust and anti-friction properties.
Optimized Spiral Flutes: This indexable drill body features a precision-engineered spiral flute geometry for rapid chip evacuation. The wide chip-breaker grooves ensure that metal chips are broken efficiently and flushed out by internal coolant, maintaining tool stability in CNC drilling operations.
Recommended Cutting Parameters
Maximize your CNC lathe tool efficiency with these baseline settings for the 49mm U-drill:
- Cutting Speed (Vc): 110 - 190 m/min (Depending on material).
- Feed Rate (f): 0.07 - 0.16 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 49}$$
- Coolant: High-pressure internal cooling is mandatory to clear chips effectively.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Cost-effective).
- Exceptional stability on uneven entry surfaces.
- Lower cutting resistance than square insert designs.
- Requires high spindle power (kW) for 49mm bores.
- Typical tolerance (+0.1/-0.2mm); best for roughing.

Frequently Asked Questions
Q: Does this include the Torx wrench and screws?
A: Yes, all BEYOND drill bodies come with the required insert screws and the matching Torx wrench.
Q: Can I use this for blind holes?
A: Absolutely. The WC U-drill provides a relatively flat bottom, making it perfect for blind hole boring.
Q: Is internal cooling necessary?
A: For a 49mm diameter, internal cooling is highly recommended to flush out chips and protect the carbide edges from overheating.
Quick Tip: 2D vs. 5D Depth Comparison
Choosing the right depth is crucial. 2D drills (like this SD49 model) provide the highest rigidity and are best for roughing. 3D to 5D drills allow for deeper hole reach but require much higher coolant pressure and reduced feed rates to avoid tool deflection and chip clogging.
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.
