BEYOND WC32-3D-SD36.5-WC06
Precision 3D Indexable U-Drill | 36.5mm Industrial CNC Tooling
Efficient 36.5mm Indexable Holemaking
The BEYOND WC32-3D-SD36.5-WC06 is a professional-grade high-efficiency indexable insert drill designed for rapid metal removal. As a specialized fast hole U-drill, it features a 36.5mm 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 & Unit Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|

Recommended Cutting Parameters
For optimal performance in metal boring, follow these standard guidelines:
- Cutting Speed (Vc): 100 - 160 m/min (Standard Steel).
- Feed Rate (f): 0.05 - 0.14 mm/rev.
- Spindle Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 36.5}$$
- 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 36.5mm 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 (Excellent economy).
- Stable drilling entry on rough or curved surfaces.
- Lower cutting resistance compared to square insert U-drills.
- Requires stable spindle power for 36.5mm diameters.
- Standard tolerance is roughly +0.1/+0.2mm (suitable for roughing).
Verified Customer Feedback
"Solid Build" - M. Schmid (Germany)
Handles 36.5mm holes in structural steel with no issues. Very rigid body.
"Efficient Chips" - Robert L. (USA)
The internal coolant and flute design clear chips out of the 3D depth perfectly.
"Best ROI" - Kenji Y. (Japan)
The 3-edge WC inserts make our drilling costs much lower than before.
"Great Quality" - Liam G. (Australia)
BEYOND brand tools never disappoint. The nickel plating is high-end.
"Precision Fit" - D. Rossi (Italy)
The WC06 inserts fit perfectly. Highly accurate for this price range.
Frequently Asked Questions
Q: Does this include the carbide inserts?
A: No, this is the 36.5mm U-drill body only. WCMX06 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 standard 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.
