Material & Flute Geometry Analysis
Premium Alloy Steel: The 46mm U-drill body is manufactured from hardened alloy steel (20CrMnTi), featuring a nickel-plated surface to prevent chip welding and increase wear resistance during high-torque boring.
Optimized Chip-Breaker Flute: This tool utilizes a spiral flute geometry designed for efficient chip evacuation. The internal coolant channels allow high-pressure fluid to flush out metal chips directly from the cutting zone, reducing heat buildup and preventing tool failure in deep hole boring.
Recommended Cutting Parameters
For the best results with the BEYOND 46mm indexable drill, follow these baseline recommendations:
- Cutting Speed (Vc): 110 - 180 m/min (Depending on material).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 46}$$
- Coolant: Internal cooling is highly recommended for 46mm diameters.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 cutting edges (Economic choice).
- Lower cutting resistance than square insert drills.
- Stable entry on rough surfaces.
- Requires high-power CNC spindles for a 46mm cut.
- Roughing tolerance (+0.1/-0.2mm); not for precision finishing.

Frequently Asked Questions
Q: Does this drill include the carbide inserts?
A: No, this is the 46mm drill body only. Inserts must be purchased separately.
Q: Is this drill compatible with high-pressure coolant?
A: Yes, it is designed with internal cooling ports specifically for high-pressure systems to flush chips efficiently.
Q: What is the benefit of the 2D length?
A: 2D drills provide the highest rigidity, making them ideal for short, large-diameter holes where precision is key.
Pro-Tip: Choosing Drill Depth (2D vs 5D)
2D Model (This tool): Best for stability and shorter holes (up to 92mm depth). Higher resistance to deflection.
3D to 5D Models: Necessary for deep boring but requires significantly higher coolant pressure and more conservative feed rates to avoid vibration 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.
