BEYOND WC40-3D-SD42-WC08
Precision 3D Indexable U-Drill | 42mm Industrial CNC Tooling
Efficient 42mm Indexable Holemaking
The BEYOND WC40-3D-SD42-WC08 is a professional-grade high-efficiency indexable insert drill designed for large-diameter metal removal. As a specialized fast hole U-drill, it features a 42mm cutting diameter with a 3D depth ratio. This tool is engineered for internal cooling drilling, ensuring superior chip evacuation in carbon steel, alloy steel, and heavy-duty industrial applications.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 42.0 mm | 1.653" |
| Shank Diameter | 40.0 mm | 1.575" |
| Effective Drilling Depth | 126.0 mm | 4.961" |
Recommended Cutting Parameters
For optimal performance in metal boring, follow these standard guidelines:
- Cutting Speed (Vc): 100 - 160 m/min (Steel/Stainless).
- Feed Rate (f): 0.08 - 0.18 mm/rev.
- Spindle Speed (N): $$N = \frac{Vc \times 1000}{\pi \times D}$$
- Coolant: High-pressure internal cooling is mandatory to ensure chip flushing.
Material & Flute Geometry Breakdown
Our indexable tool holder is manufactured from premium alloy steel (20CrMnTi) with specialized quenching to ensure a hardness of 45-50 HRC. The oversized spiral flute geometry is designed for high-volume chip evacuation, preventing chip welding in 42mm large-diameter drilling. The nickel-plated surface provides excellent corrosion resistance and smooth chip flow during continuous operation.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 usable cutting edges (High economy).
- Stable entry even on uneven or sloped surfaces.
- Lower power consumption than equivalent SP series drills.
- Requires high spindle torque for 42mm diameter.
- Tolerance is roughly +0.2mm (Roughing tool).
Verified Customer Feedback
"Highly Robust" - Klaus M. (Germany)
Handles 42mm holes in alloy steel with zero vibration. Rigidity is top-tier.
"Fast Chip Flow" - Mark T. (USA)
The spiral flutes clear chips perfectly. No clogging in deep holes.
"Cost-Effective" - Sato K. (Japan)
The WC trigon inserts are much cheaper per edge than my previous drills.
"Professional Grade" - Liam W. (Australia)
Body shows no wear after weeks of production. Highly recommend BEYOND tools.
"Perfect Fit" - David R. (UK)
The WC08 inserts seat perfectly. High accuracy for a roughing drill.
Frequently Asked Questions
Q: Does this include the carbide inserts?
A: No, this is the 42mm U-drill body only. WCMX08 inserts are sold separately.
Q: Can I use this for blind holes?
A: Yes, it is ideal for blind holes and produces a relatively flat bottom compared to twist drills.
Q: What is the benefit of the WC series?
A: WC Trigon inserts offer 3 usable cutting edges, significantly reducing your cost-per-hole compared to SP inserts.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for CNC holemaking success:
- 2D/3D (This Model): Maximum rigidity; best for large diameter roughing and stable machining.
- 4D: The universal standard; balanced for most general production needs.
- 5D: Specialized long reach drilling; requires high-pressure coolant and reduced feed rates.
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.
