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
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
