BEYOND WC40-2D-SD54-WC08
Industrial 54mm 2D Indexable U-Drill | High-Torque CNC Performance
High-Efficiency 54mm Indexable Metal Boring
The BEYOND WC40-2D-SD54-WC08 is a professional-grade indexable insert drill engineered for heavy material removal in CNC machining centers. As a specialized fast hole U-drill, it features a massive 54mm cutting diameter with a 2D depth ratio. This tool is optimized for internal cooling drilling in carbon steel, alloy steel, and stainless steel, ensuring maximum productivity for industrial-scale large diameter boring. Originating from China, BEYOND tooling combines high durability with cost-effective precision.

Material Integrity & Optimized Flute Design
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), this 54mm indexable drill body is designed to absorb vibration and withstand high cutting forces. The surface is nickel-plated for superior corrosion resistance and anti-friction performance.
Large-Capacity Spiral Flutes: The optimized spiral flute geometry is specifically engineered for efficient chip removal. Combined with internal coolant ports, the flute design prevents "chip welding" and ensures continuous operation in heavy machining environments.
Recommended Cutting Parameters
Optimize your CNC lathe tool efficiency with these baseline settings for the 54mm U-drill:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 54}$$
- Coolant Strategy: High-pressure internal cooling is mandatory for clearing heavy chips.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Lowers cost-per-hole).
- Stable entry even on uneven or curved workpiece surfaces.
- Balanced cutting forces reduce machine spindle wear.
- Requires high spindle power (kW) for 54mm diameters.
- Hole tolerance is roughly +0.10mm to +0.20mm (Roughing grade).

Frequently Asked Questions
Q: Is this drill body compatible with other brands of WC08 inserts?
A: Yes, it is designed to standard ISO specifications and fits standard WCMX/WCMT 0804 inserts.
Q: Can I use this for blind holes?
A: Absolutely. The U-drill provides a relatively flat bottom, making it perfect for blind hole boring in industrial parts.
Q: Is internal cooling necessary?
A: For a 54mm diameter, internal cooling is highly recommended to flush chips and prevent heat build-up on the carbide edges.
Quick Tip: 2D vs. 5D Depth Choice
Choosing the right depth is crucial for tool life. 2D drills (like this SD54 model) offer the highest rigidity and are best for roughing and shallow holes. 3D to 5D drills allow for deeper reach but require significantly higher coolant pressure and more conservative feed rates to avoid vibration and tool failure.
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.
