BEYOND WC32-4D-SD36-WC06
Professional 4D Indexable U-Drill | 36mm Precision CNC Machining
High-Efficiency 36mm Indexable Drilling
The BEYOND WC32-4D-SD36-WC06 is a professional indexable insert drill engineered for precision hole making. Featuring a 36mm 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 Explained
Technical Data & Metric/Imperial Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 36.0 mm | 1.417" |
| Shank Diameter | 32.0 mm | 1.260" |
| Drilling Depth (4D) | 144.0 mm | 5.669" |
Recommended Cutting Parameters
Optimize your CNC metalworking results by following these guidelines:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.06 - 0.14 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for a 36mm diameter to flush chips effectively and protect the tool body.
Material Excellence & Wide Chip Flute Geometry
Constructed from high-performance alloy steel with an anti-vibration quenching process, the WC06 insert holder offers exceptional toughness. The wide spiral flute geometry is precision-machined to ensure "forced" chip removal, significantly reducing the risk of tool breakage during large diameter drilling.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Stable entry even on uneven or curved workpiece surfaces.
- Higher feed rates than twist drills for high-speed drilling.
- Requires high spindle power for 36mm diameter.
- Surface finish may require secondary boring for high-precision bores.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for CNC tooling stability:
- 2D/3D: Highest rigidity; ideal for shallow holes and high-feed roughing.
- 4D (This Model): The versatile standard for deep-hole machining.
- 5D: Maximum reach; requires extreme coolant pressure and lower feed rates to maintain straightness.
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.
