BEYOND WC40-2D-SD41-WC06
Industrial 41mm 2D Indexable U-Drill | Precision CNC Fast Hole Boring
Efficient 41mm Indexable Metal Boring Solution
The BEYOND WC40-2D-SD41-WC06 is a heavy-duty indexable insert drill engineered for rapid material removal in CNC machining centers. As a specialized fast hole U-drill, it features a 41mm 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 heat dissipation for large diameter metal boring projects.

High-Grade Material & Optimized Flute Design
Premium Body Material: Forged from high-strength quenched alloy steel (20CrMnTi), the 41mm U-drill body offers superior surface hardness and vibration resistance. This prevents deformation under high-torque boring. The nickel-plated coating provides rust resistance and smooth chip evacuation.
Optimized Spiral Flutes: This indexable drill body features precision-engineered spiral flute geometry for rapid chip flow. The wide chip-breaker grooves ensure that metal chips are broken efficiently and flushed out by internal coolant, protecting the WC06 insert holder from premature wear during CNC drilling operations.
Recommended Cutting Parameters
Maximize your CNC lathe tool efficiency with these baseline settings for the 41mm U-drill:
- Cutting Speed (Vc): 120 - 220 m/min (Material dependent).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 41}$$
- Coolant Strategy: Internal cooling is mandatory for high-pressure chip flushing.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 3 cutting edges (Economical).
- Stable entry on uneven or curved workpiece surfaces.
- Balanced cutting forces reduce spindle vibration.
- Requires high spindle power for 41mm diameters.
- Standard 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 include the necessary insert screws and the correct Torx wrench.
Q: Can I use this for blind holes?
A: Yes. The WC U-drill provides a relatively flat bottom, making it perfect for blind hole boring in metalwork.
Q: Is internal cooling mandatory?
A: For a 41mm diameter, internal cooling is highly recommended to flush heavy chips and protect carbide edges.
Quick Tip: 2D vs. 5D Depth Selection
Choosing the right depth is vital for stability. 2D drills (like this SD41 model) provide the highest rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper hole reach but require much higher coolant pressure and reduced feed rates to avoid vibration.
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.
