BEYOND WC32-4D-SD29-WC05
Precision 4D Indexable U-Drill | 29mm High-Performance CNC Drilling
Industrial 29mm Indexable Drilling Solution
The BEYOND WC32-4D-SD29-WC05 is a high-rigidity indexable insert drill engineered for rapid metal removal in CNC environments. Featuring a 29mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. It is optimized for processing carbon steel, alloy steel, and stainless steel with maximum stability during heavy-duty CNC machining.
Model Code Specification
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 29.0 mm | ~1.142" |
| Shank Diameter | 32.0 mm | 1-1/4" (Approx.) |

Recommended Cutting Parameters
Optimize your CNC holemaking with these standard guidelines for WC U-drills:
- Spindle Speed (V): 120 - 200 m/min (Subject to material hardness).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for effective chip evacuation and protecting the fast hole drill body.
Premium Material & Optimized Spiral Flute
Constructed from high-performance hardened alloy steel with specialized anti-vibration quenching, this WC05 insert holder ensures maximum rigidity. The large spiral flute geometry is specifically engineered for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in 29mm deep hole drilling. The nickel-plated body minimizes friction and prevents chip welding during high-speed operations.
WC Series U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (High cost-efficiency).
- Stable performance on uneven entry surfaces compared to SP series.
- Excellent chip breaking on low-carbon and alloy steels.
- Requires higher spindle torque and power.
- Surface finish may require a secondary finishing pass for high-precision bores.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for CNC tooling success:
- 2D/3D: Maximum rigidity; best for shallow holes and high-feed roughing.
- 4D (This Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized long reach drill. Requires extreme coolant pressure and precise alignment.
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.
